This is where layout comes into play.<\/p>\n<p class=\"wp-block-paragraph\">Good layout in newsletters has a significant impact on brand perception, open rate, click rate and, ultimately, the effectiveness of your email marketing campaign.<\/p>\n<p class=\"wp-block-paragraph\">Some of the key aspects of effective layout include a simple, clean design, mobile adaptability, optimized loading time and the correct presentation of images and visual elements.<\/p>\n<h2 class=\"wp-block-heading\">Things to Keep in Mind When Designing an Email<\/h2>\n<p class=\"wp-block-paragraph\">Let&#8217;s get straight to the point and dive right in.<\/p>\n<p class=\"wp-block-paragraph\"><span style=\"text-decoration: underline;\">I&#8217;m going to tell you right now a few things you need to keep in mind that will be vital so that the emails you send from now on help you convert more:<\/span><\/p>\n<h3 class=\"wp-block-heading\">\ud83d\udccc Watch the weight of your images<\/h3>\n<p class=\"wp-block-paragraph\">Images are heavy. Don&#8217;t doubt that for a second. Optimizing images for email marketing is crucial so that your sends don&#8217;t slow down.<\/p>\n<p class=\"wp-block-paragraph\">If they slow down, it can hurt the email&#8217;s visibility (or it may simply not display at all), and that can be a serious problem, especially for conversions.<\/p>\n<p class=\"wp-block-paragraph\">There are many <a href=\"https:\/\/mailrelay.com\/en\/blog\/2023\/06\/06\/email-marketing-the-best-tool-to-optimize-your-campaigns\/\" target=\"_blank\" rel=\"noopener\"><strong>email marketing tools<\/strong><\/a> that can help you with this task. Use them and optimize your images right away.<\/p>\n<h3 class=\"wp-block-heading\">\ud83d\udccc Insert images that match the content of the email<\/h3>\n<p class=\"wp-block-paragraph\">They say a picture is worth a thousand words. And although I don&#8217;t entirely agree, it&#8217;s true that images help a lot.<\/p>\n<p class=\"wp-block-paragraph\">If you use images that match the text of the email, such as:<\/p>\n<ul class=\"wp-block-list\">\n<li>An image of a beautiful valley if you want people to book a room at a mountain hotel<\/li>\n<li>An image of a surfer to promote a city, a town or a hotel for summer vacations<\/li>\n<li>Different images of pants, dresses or shirts if you&#8217;re promoting a store&#8217;s products<\/li>\n<li>Etc., etc.<\/li>\n<\/ul>\n<p class=\"wp-block-paragraph\">You&#8217;ll most likely grab more attention and your conversions will be higher.<\/p>\n<h3 class=\"wp-block-heading\">\ud83d\udccc Write eye-catching text<\/h3>\n<p class=\"wp-block-paragraph\">Following on from the previous point, if you insert images that match the content of your email, the text should be eye-catching too.<\/p>\n<p class=\"wp-block-paragraph\">It&#8217;s the best way for both the images and the text to grab the subscriber&#8217;s attention. As a result, you can get better outcomes, because <a href=\"https:\/\/mailrelay.com\/en\/blog\/2017\/03\/14\/5-persuasion-techniques-you-need-to-use-in-your-content\/\" target=\"_blank\" rel=\"noopener\">persuasion<\/a> comes into play here.<\/p>\n<p class=\"wp-block-paragraph\">And when I say text, I mean all of the content itself: from the headline to the last full stop you write.<\/p>\n<p class=\"wp-block-paragraph\">That said, to get the subscriber in the right mood, it&#8217;s best for the headline to be highly visible and contain a clear, concise message that highlights the strongest points of your promotion.<\/p>\n<h3 class=\"wp-block-heading\">\ud83d\udccc Simple design works too<\/h3>\n<p class=\"wp-block-paragraph\">In the last two sections I&#8217;ve highlighted how important images are. That&#8217;s really true. However, <span style=\"text-decoration: underline;\">simple designs, that is, without images, also work<\/span>.<\/p>\n<p class=\"wp-block-paragraph\">Why? Because, depending on your intentions, it&#8217;s better to do one thing or the other.<\/p>\n<p class=\"wp-block-paragraph\">For example, in promotional sends it&#8217;s ideal for the email to be very visual, because the goal is to persuade the subscriber to then make a purchase, sign up or make a booking.<\/p>\n<p class=\"wp-block-paragraph\">However, if what you&#8217;re looking for is closeness, talking directly to the reader or expressing an idea of your own, simplicity is key.<\/p>\n<p class=\"wp-block-paragraph\">You don&#8217;t need to persuade with images; you already do that with words.<\/p>\n<p class=\"wp-block-paragraph\">In this case, <strong>a simple design can be ideal for bloggers<\/strong> although, naturally, everyone can have their own point of view.<\/p>\n<h3 class=\"wp-block-heading\">\ud83d\udccc Structure of the ideal newsletter<\/h3>\n<p class=\"wp-block-paragraph\">All the previous tips are worth their weight in gold because they can make the difference in the newsletter you create.<\/p>\n<p class=\"wp-block-paragraph\">However, <strong>its structure is decisive<\/strong>. It&#8217;s what will help the subscriber understand, from the very first moment, the message you want to get across.<\/p>\n<p class=\"wp-block-paragraph\">To do this, you can follow some established guidelines that will help you create the ideal newsletter:<\/p>\n<ul class=\"wp-block-list\">\n<li>Write an eye-catching headline<\/li>\n<li>Write a brief, concise description<\/li>\n<li>Write content that hooks readers from the very first moment<\/li>\n<li>Insert images or not, depending on your intentions<\/li>\n<\/ul>\n<p class=\"wp-block-paragraph\">That said, there&#8217;s no point in creating a great newsletter <strong>if you then don&#8217;t have your subscribers properly segmented<\/strong>.<\/p>\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"630\" height=\"340\" src=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2017\/05\/como-hacer-una-newsletter.jpg\" alt=\"Choose simple, responsive, lightweight designs\" class=\"wp-image-34229\" srcset=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2017\/05\/como-hacer-una-newsletter.jpg 630w, https:\/\/mailrelay.com\/wp-content\/uploads\/2017\/05\/como-hacer-una-newsletter-300x162.jpg 300w, https:\/\/mailrelay.com\/wp-content\/uploads\/2017\/05\/como-hacer-una-newsletter-110x59.jpg 110w\" sizes=\"auto, (max-width: 630px) 100vw, 630px\"><\/figure>\n<p class=\"wp-block-paragraph\">\n<h2 class=\"wp-block-heading\"><strong>10 Tips for Laying Out Your Newsletters<\/strong>: Dimensions, Sizes\u2026<\/h2>\n<h3 class=\"wp-block-heading\"><strong>1- Choose simple, responsive, lightweight designs<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">Newsletters should have a simple design that displays correctly in all email clients, as well as on different platforms.<\/p>\n<p class=\"wp-block-paragraph\">When laying out your newsletter, we recommend using standard fonts and flat background colors, and reducing the use of images in favor of text.<\/p>\n<p class=\"wp-block-paragraph\">Remember that the lighter your newsletters are, the faster they will download. It&#8217;s best not to let your HTML weigh more than 1 MB.<\/p>\n<h4 class=\"wp-block-heading\"><strong>\u25ba The importance of simplicity in design<\/strong><\/h4>\n<p class=\"wp-block-paragraph\">Simplicity in a newsletter&#8217;s design is crucial to hold the reader&#8217;s attention and ensure easy, comfortable reading.<\/p>\n<p class=\"wp-block-paragraph\">A simple, clean design makes it easier to identify the key elements of the content and avoids the visual overload that can lead recipients to stop reading or even unsubscribe.<\/p>\n<p class=\"wp-block-paragraph\">In addition, a simple design is usually easier to adapt to different devices and email clients.<\/p>\n<h4 class=\"wp-block-heading\"><strong>\u25ba Ensuring compatibility on mobile devices<\/strong><\/h4>\n<p class=\"wp-block-paragraph\">More and more people access their email on mobile devices, so it&#8217;s essential to make sure newsletters look good on phones and tablets.<\/p>\n<p class=\"wp-block-paragraph\">A responsive design automatically adapts to different screen sizes, ensuring an optimal reading experience for all users.<\/p>\n<p class=\"wp-block-paragraph\"><strong>To achieve this, it&#8217;s important to use a fluid layout, use legible font sizes and avoid elements that can cause problems on mobile devices<\/strong>, such as large images or complex interactive elements.<\/p>\n<h4 class=\"wp-block-heading\"><strong>\u25ba Reducing loading time<\/strong><\/h4>\n<p class=\"wp-block-paragraph\">Loading time is a critical factor in the user experience and can affect open rates and engagement with the newsletter.<\/p>\n<p class=\"wp-block-paragraph\">A simple, lightweight design, with optimized images and no unnecessary elements, helps reduce loading time.<\/p>\n<p class=\"wp-block-paragraph\">This is especially important on mobile devices, where the internet connection can be slower and users tend to be less tolerant of waiting for content to load.<\/p>\n<p class=\"wp-block-paragraph\"><strong>To reduce loading time, it&#8217;s important to minimize the use of large images, avoid multimedia files and compress the HTML code whenever possible.<\/strong><\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"250\" src=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-1.jpg\" alt=\"Use responsive designs\" class=\"wp-image-6535\" title=\"Use responsive designs\" srcset=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-1.jpg 600w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-1-300x125.jpg 300w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-1-110x46.jpg 110w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\"><\/figure>\n<\/div>\n<p class=\"wp-block-paragraph\">\n<h3 class=\"wp-block-heading\"><strong>2- Use pure HTML<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">The HTML you use should be as simple as possible, avoiding scripts, styles, effects, forms, etc.<\/p>\n<p class=\"wp-block-paragraph\">Your newsletters should include both HTML and plain-text versions in the message.<\/p>\n<p class=\"wp-block-paragraph\">By default, the <strong>Mailrelay<\/strong> system generates the plain-text message from the HTML message, which is more effective, since a difference between the two texts can lead to a higher spam score.<\/p>\n<h4 class=\"wp-block-heading\"><strong>\u25ba Advantages of using pure HTML in newsletters<\/strong><\/h4>\n<p class=\"wp-block-paragraph\">Using pure HTML in newsletters offers several advantages that contribute to greater compatibility and deliverability across different email clients and devices. <strong>Some of these advantages include:<\/strong><\/p>\n<ul class=\"wp-block-list\">\n<li><strong>Compatibility:<\/strong> Pure HTML is widely supported by most email clients, which ensures that your newsletter displays correctly on a wide variety of platforms and devices.<\/li>\n<li><strong>Control:<\/strong> When you use pure HTML, you have greater control over the look and design of your newsletter, which lets you fine-tune and optimize it to your audience&#8217;s needs.<\/li>\n<li><strong>Deliverability:<\/strong> Using pure HTML instead of external CSS and JavaScript reduces the likelihood that your newsletter will be flagged as spam or blocked by email filters. This improves deliverability rates and increases the chances that your message will reach your subscribers&#8217; inbox.<\/li>\n<li><strong>Loading time:<\/strong> Pure HTML generally has a smaller file size than emails that use external CSS and JavaScript. This means your newsletter will load faster in your subscribers&#8217; inbox, which will improve the user experience and increase the chances that they&#8217;ll interact with your content.<\/li>\n<\/ul>\n<h4 class=\"wp-block-heading\"><strong>\u25ba Avoiding external CSS and JavaScript<\/strong><\/h4>\n<p class=\"wp-block-paragraph\">Although using CSS and JavaScript can offer advantages in terms of design and functionality, it can also cause problems in newsletters for the following reasons:<\/p>\n<ul class=\"wp-block-list\">\n<li><strong>Incompatibility:<\/strong> Some email clients don&#8217;t fully support CSS and JavaScript, which can result in your newsletter displaying incorrectly or incompletely.<\/li>\n<li><strong>Deliverability:<\/strong> Emails that use external CSS and JavaScript may be more likely to be flagged as spam or blocked by email filters, which negatively affects deliverability rates.<\/li>\n<li><strong>Loading time:<\/strong> External CSS and JavaScript files can increase your newsletter&#8217;s file size, resulting in longer loading times and a worse user experience.<\/li>\n<li><strong>Security:<\/strong> Some email clients may automatically block active content, such as JavaScript, for security reasons, which affects your newsletter&#8217;s functionality.<\/li>\n<\/ul>\n<p class=\"wp-block-paragraph\">In short, it&#8217;s advisable to avoid external CSS and JavaScript in newsletters and opt for pure HTML whenever possible to ensure greater compatibility, deliverability and a better user experience.<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"250\" src=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-2.jpg\" alt=\"Take advantage of HTML\" class=\"wp-image-6537\" title=\"Take advantage of HTML\" srcset=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-2.jpg 600w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-2-300x125.jpg 300w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-2-110x46.jpg 110w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\"><\/figure>\n<\/div>\n<p class=\"wp-block-paragraph\">\n<h3 class=\"wp-block-heading\"><strong>3- Lay out your newsletter using tables<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">Despite the progress that HTML5 and CSS3 brought, email clients still haven&#8217;t fully adopted these technologies and <strong>continue to use tables<\/strong> in HTML coding.<\/p>\n<p class=\"wp-block-paragraph\">That&#8217;s why we recommend that you always lay out your newsletter using tables, to avoid unexpected results.<\/p>\n<h4 class=\"wp-block-heading\"><strong>\u25ba Why use tables instead of divs<\/strong><\/h4>\n<p class=\"wp-block-paragraph\">Although in modern web design divs and cascading style sheets (CSS) are preferable for their flexibility and ease of maintenance, in the case of newsletters, tables remain the most reliable option.<\/p>\n<p class=\"wp-block-paragraph\">The main reason is compatibility and consistency across different email clients and devices.<\/p>\n<p class=\"wp-block-paragraph\"><strong>Some of the benefits of using tables instead of divs in newsletters include:<\/strong><\/p>\n<ul class=\"wp-block-list\">\n<li><strong>Compatibility:<\/strong> Tables are supported by practically all email clients, including those with limited CSS support. This ensures that your newsletter displays consistently on all devices and platforms.<\/li>\n<li><strong>Structure:<\/strong> Tables provide a clear, easy-to-follow structure for laying out your newsletter. This makes it easier to create organized, easy-to-read designs for your subscribers.<\/li>\n<li><strong>Width control:<\/strong> Using tables lets you control the width of your newsletter effectively. This is especially useful to ensure your design looks good on mobile devices and adjusts properly to different screen sizes.<\/li>\n<\/ul>\n<h4 class=\"wp-block-heading\"><strong>\u25ba Tips for using tables efficiently in layout<\/strong><\/h4>\n<p class=\"wp-block-paragraph\">To get the most out of tables when laying out newsletters, keep the following tips in mind:<\/p>\n<ul class=\"wp-block-list\">\n<li><strong>Nest tables:<\/strong> If you need a more complex structure, you can nest tables inside other tables. However, try not to nest too many tables, to avoid complications and ensure good readability.<\/li>\n<li><strong>Use empty cells:<\/strong> If you need to add white space between elements, you can use empty cells instead of adding margins or padding with CSS. This will ensure the white space displays correctly in all email clients.<\/li>\n<li><strong>Inline styles:<\/strong> Apply inline styles to your tables and cells instead of using external cascading style sheets. This will help ensure your styles display correctly in all email clients.<\/li>\n<li><strong>Alignment and text wrapping:<\/strong> Use alignment and text-wrapping attributes in your table cells to control the position of the content effectively and ensure a tidy, consistent appearance.<\/li>\n<li><strong>Keep accessibility in mind:<\/strong> Make sure your newsletter is accessible to all users, including those with visual impairments or who use screen readers. To do this, add descriptive <strong>\u2018alt\u2019<\/strong> attributes to images and use heading tags and clear text to structure your content.<\/li>\n<\/ul>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"250\" src=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-3.jpg\" alt=\"Use tables in your layouts\" class=\"wp-image-6538\" title=\"Use tables in your layouts\" srcset=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-3.jpg 600w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-3-300x125.jpg 300w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-3-110x46.jpg 110w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\"><\/figure>\n<\/div>\n<p class=\"wp-block-paragraph\">\n<h3 class=\"wp-block-heading\"><strong>4- Dimensions and size: Don&#8217;t exceed 600px in width<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">Many email clients don&#8217;t display your email full screen, but through a preview pane that is approximately 600 px wide.<\/p>\n<p class=\"wp-block-paragraph\">You should also keep in mind that wider images are more likely to be <a href=\"https:\/\/mailrelay.com\/en\/blog\/2023\/02\/21\/what-is-spam-how-to-prevent-emails-from-landing-in-the-spam-folder\/\" target=\"_blank\" rel=\"noopener\">considered spam<\/a>.<\/p>\n<p class=\"wp-block-paragraph\">It&#8217;s important that you respect that measurement, so that your newsletters can be displayed correctly.<\/p>\n<h4 class=\"wp-block-heading\"><strong>\u25ba Adaptability to different devices and email clients<\/strong><\/h4>\n<p class=\"wp-block-paragraph\">The main reason for not exceeding 600px in width is adaptability.<\/p>\n<p class=\"wp-block-paragraph\">Most email clients and mobile devices, such as phones and tablets, have limitations on the maximum width they can display.<\/p>\n<p class=\"wp-block-paragraph\">By keeping your newsletter within 600px in width, you make sure it&#8217;s compatible with most platforms and displays correctly on all devices, avoiding horizontal scrolling problems and ensuring an optimal user experience.<\/p>\n<h4 class=\"wp-block-heading\"><strong>\u25ba Readability and user experience<\/strong><\/h4>\n<p class=\"wp-block-paragraph\">Another reason to keep your newsletter&#8217;s width below 600px is readability and user experience.<\/p>\n<p class=\"wp-block-paragraph\">A narrower design makes content easier to read on both mobile and desktop devices, since users won&#8217;t have to scroll horizontally to read all of the content.<\/p>\n<p class=\"wp-block-paragraph\">In addition, by limiting the width, you can better control the design and arrangement of the elements in your newsletter, which makes it easier to create a clean, organized design that&#8217;s easy for your subscribers to follow.<\/p>\n<p class=\"wp-block-paragraph\"><strong>Ultimately, keeping your newsletter&#8217;s width within 600px improves readability<\/strong> and ensures a pleasant user experience for your subscribers.<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"250\" src=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-4.jpg\" alt=\"Don't exceed 600px in width\" class=\"wp-image-6539\" title=\"Don't exceed 600px in width\" srcset=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-4.jpg 600w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-4-300x125.jpg 300w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-4-110x46.jpg 110w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\"><\/figure>\n<\/div>\n<p class=\"wp-block-paragraph\">\n<h3 class=\"wp-block-heading\"><strong>5- Use inline styles<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">Some email clients don&#8217;t support the style tag in the email header.<\/p>\n<p class=\"wp-block-paragraph\">To avoid this problem, it would be best to use inline styles.<\/p>\n<h4 class=\"wp-block-heading\"><strong>\u25ba Benefits of inline styles in newsletters<\/strong><\/h4>\n<p class=\"wp-block-paragraph\">Inline styles offer several benefits compared to using external or internal cascading style sheets (CSS):<\/p>\n<ul class=\"wp-block-list\">\n<li><strong>Greater compatibility:<\/strong> Some email clients may not interpret CSS style sheets correctly, especially if they&#8217;re linked externally.

By using inline styles, you reduce the likelihood of your email being flagged as spam.<\/li>\n<li><strong>Smaller file size:<\/strong> By applying inline styles, you eliminate the need to load additional CSS files, which reduces the total size of the email and speeds up loading time.<\/li>\n<\/ul>\n<h4 class=\"wp-block-heading\"><strong>\u25ba How to apply inline styles in HTML<\/strong><\/h4>\n<p class=\"wp-block-paragraph\">To apply inline styles in HTML, you simply need to add the \u201cstyle\u201d attribute to HTML tags and define the corresponding CSS properties.<\/p>\n<p class=\"wp-block-paragraph\">Here&#8217;s an example of how to apply inline styles to an element:<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"250\" src=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-5.jpg\" alt=\"Code your styles correctly to avoid problems in email clients\" class=\"wp-image-6541\" title=\"Code your styles correctly to avoid problems in email clients\" srcset=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-5.jpg 600w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-5-300x125.jpg 300w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-5-110x46.jpg 110w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\"><\/figure>\n<\/div>\n<p class=\"wp-block-paragraph\">\n<h3 class=\"wp-block-heading\"><strong>6- Avoid unexpected results in your images<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">When you use sliced images, or one image next to another, with a table structure, each image must have the style \u201cdisplay:block\u201d.<\/p>\n<p class=\"wp-block-paragraph\">That&#8217;s because email clients such as Gmail automatically generate an unwanted white space between the images, breaking the design of our newsletters, just as you can see below:<\/p>\n<h4 class=\"wp-block-heading\"><strong>\u25ba How to optimize images for different email clients<\/strong><\/h4>\n<ul class=\"wp-block-list\">\n<li><strong>Use the \u201calt\u201d attribute:<\/strong> Some email clients may block images by default.

Avoid using less common formats that may not be supported by some email clients.<\/li>\n<\/ul>\n<h4 class=\"wp-block-heading\"><strong>\u25ba Using high-quality, well-formatted images<\/strong><\/h4>\n<ul class=\"wp-block-list\">\n<li><strong>Quality and appropriate resolution:<\/strong> Make sure to use high-quality images with the appropriate resolution to ensure a sharp, professional appearance. However, avoid images with an excessively large file size, as this could increase the email&#8217;s loading time and negatively affect the user experience.<\/li>\n<li><strong>Optimize your images for the web:<\/strong> Use online image compression tools to reduce file size without compromising visual quality. This will improve your newsletter&#8217;s loading time and ensure a smoother experience for your subscribers.<\/li>\n<li><strong>Proper proportions:<\/strong> Make sure your images have proper proportions and fit your newsletter&#8217;s design. Avoid stretching or squashing images disproportionately, as this can result in an unprofessional, unattractive appearance.<\/li>\n<\/ul>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"250\" src=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-6.jpg\" alt=\"Example of how two images look side by side\" class=\"wp-image-6542\" title=\"Example of how two images look side by side\" srcset=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-6.jpg 600w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-6-300x125.jpg 300w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-6-110x46.jpg 110w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\"><\/figure>\n<\/div>\n<p class=\"wp-block-paragraph\">\n<h3 class=\"wp-block-heading\"><strong>7- Avoid attaching files<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">Anti-spam filters look unfavorably on them, especially if they&#8217;re doc, exe, zip, etc., which can contain viruses.<\/p>\n<p class=\"wp-block-paragraph\">It&#8217;s advisable to upload attachments to an FTP server and insert a link in the body of the message so that recipients can download them.<\/p>\n<p class=\"wp-block-paragraph\">Also, this way you&#8217;ll get feedback in your statistics on who has opened the file.<\/p>\n<h4 class=\"wp-block-heading\"><strong>\u25ba Security and deliverability issues related to attachments<\/strong><\/h4>\n<ul class=\"wp-block-list\">\n<li><strong>Spam filters:<\/strong> Attachments can cause your email to be flagged as spam by email filters, since attachments are often used by spammers and scammers to distribute malicious content.<\/li>\n<li><strong>Email size limits:<\/strong> Attachments can significantly increase the size of your emails, which can cause them to be rejected or delivered late if they exceed the size limits set by email providers.<\/li>\n<li><strong>Security risks:<\/strong> Attachments can contain viruses and malware, which can put recipients&#8217; security at risk. Even if your files are safe, recipients may be reluctant to open them for fear of infecting their devices.<\/li>\n<\/ul>\n<h4 class=\"wp-block-heading\"><strong>\u25ba Alternatives for sharing files in newsletters<\/strong><\/h4>\n<ul class=\"wp-block-list\">\n<li><strong>Links to files hosted online:<\/strong> Instead of attaching files directly, upload the files to an online hosting service, such as Google Drive or Dropbox, and provide links to these files in your newsletter. This way, subscribers will be able to access the files without having to download them directly from the email.<\/li>\n<li><strong>Embed multimedia content:<\/strong> If you want to share images, videos or presentations in your newsletter, consider embedding these elements directly in the body of the email using HTML. This will allow subscribers to view the content without having to download additional files.<\/li>\n<li><strong>Provide links to relevant web pages:<\/strong> If the content you want to share is available online, simply include links to the relevant web pages instead of attaching files. This makes it easier to access the content and keeps your email size under control.<\/li>\n<\/ul>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"250\" src=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-7.jpg\" alt=\"Avoid attachments\" class=\"wp-image-6543\" title=\"Avoid attachments\" srcset=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-7.jpg 600w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-7-300x125.jpg 300w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-7-110x46.jpg 110w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\"><\/figure>\n<\/div>\n<p class=\"wp-block-paragraph\">\n<h3 class=\"wp-block-heading\"><strong>8- Optimize your images<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">To reduce the weight of your images without losing quality, you need to compress them in an editing program, or you can use a tool such as Kraken.io, a web app that works wonders.<\/p>\n<h4 class=\"wp-block-heading\"><strong>\u25ba Reducing size and choosing the right format<\/strong><\/h4>\n<ul class=\"wp-block-list\">\n<li><strong>Compress images:<\/strong> Use image compression tools to reduce the size of your files without compromising visual quality. Tools such as TinyPNG or Compressor.io let you compress PNG and JPEG images efficiently.<\/li>\n<li><strong>Choose the right format:<\/strong> Pick the most suitable image format for each case. For example, use JPEG for images with lots of colors and detail, and PNG for images with areas of solid color and transparency.<\/li>\n<li><strong>Resize images:<\/strong> Make sure your images are the right size for use in the newsletter. You don&#8217;t need to use high-resolution images if they&#8217;re going to be displayed at a smaller size. Resize your images to the right size before uploading them.<\/li>\n<\/ul>\n<h4 class=\"wp-block-heading\"><strong>\u25ba Optimization techniques to improve loading speed<\/strong><\/h4>\n<ul class=\"wp-block-list\">\n<li><strong>Lazy loading:<\/strong> Implement lazy loading in your newsletters so that images load only when they&#8217;re visible on the recipient&#8217;s screen. This helps improve initial loading speed and reduces data consumption for users.<\/li>\n<li><strong>Serve images from a CDN:<\/strong> Use a content delivery network (CDN) to serve your images. A CDN speeds up image loading by distributing images from servers located in different parts of the world, which reduces latency and ensures faster delivery.<\/li>\n<li><strong>Use the \u201calt\u201d attribute:<\/strong> Always include the \u201calt\u201d attribute in your image tags to provide a text description of the image. This improves accessibility and lets users understand the content of the image even if it doesn&#8217;t load correctly.<\/li>\n<\/ul>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"250\" src=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-8.jpg\" alt=\"Optimize your images\" class=\"wp-image-6544\" title=\"Optimize your images\" srcset=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-8.jpg 600w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-8-300x125.jpg 300w, https:\/\/mailrelay.com\/wp-content\/uploads\/2014\/08\/10-claves-para-maquetar-tus-newsletters-8-110x46.jpg 110w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\"><\/figure>\n<\/div>\n<p class=\"wp-block-paragraph\">\n<h3 class=\"wp-block-heading\"><strong>9- Always include legal text<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">For your website to be legal, it must contain:<\/p>\n<ul class=\"wp-block-list\">\n<li>An explanation of how the email addresses were obtained<\/li>\n<li>A link to your data protection policy page<\/li>\n<li>A statement of our unequivocal commitment to comply with the rules on sending commercial emails, and a way for subscribers who wish to report a complaint or suggestion to give feedback<\/li>\n<\/ul>\n<h4 class=\"wp-block-heading\"><strong>\u25ba Complying with applicable regulations and laws<\/strong><\/h4>\n<ul class=\"wp-block-list\">\n<li><strong>Anti-spam laws:<\/strong> Make sure you comply with the anti-spam laws of the countries where you operate or where your subscribers are located.
