It can also include the subject, the message text and CC recipients.<\/p>\n\n<p class=\"wp-block-paragraph\">You see it every time a website has a &#8220;Contact us&#8221; link that opens Gmail, Outlook or Apple Mail. Its name comes from &#8220;mail to&#8221;, and it is defined in the IETF&#8217;s <a href=\"https:\/\/www.rfc-editor.org\/rfc\/rfc6068\">RFC 6068<\/a> standard.<\/p>\n\n<h2 class=\"wp-block-heading\">How does a mailto link work?<\/h2>\n\n<p class=\"wp-block-paragraph\">A mailto link starts with <strong>mailto:<\/strong> instead of <strong>https:\/\/<\/strong>. The browser doesn&#8217;t load a page: it passes the data to the email program the user has set up.<\/p>\n\n<p class=\"wp-block-paragraph\">This is the basic structure:<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>mailto:name@yourcompany.com<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">If you want to add more data, write it after a question mark and separate each item with the &#8220;&amp;&#8221; sign:<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>mailto:name@yourcompany.com?subject=Question&amp;body=Hi<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">If the user doesn&#8217;t have an email program set up, the link does nothing or asks them to choose an app. This is one of its limitations.<\/p>\n\n<h2 class=\"wp-block-heading\">What parameters does a mailto link accept?<\/h2>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Parameter<\/th><th>What it&#8217;s for<\/th><th>Example<\/th><\/tr><\/thead><tbody><tr><td>(address)<\/td><td>Main recipient<\/td><td>mailto:sales@yourcompany.com<\/td><\/tr><tr><td>subject<\/td><td>Email subject<\/td><td>?subject=Urgent%20order<\/td><\/tr><tr><td>body<\/td><td>Message text<\/td><td>&amp;body=Hi,%20I%20would%20like%20information<\/td><\/tr><tr><td>cc<\/td><td>CC recipient<\/td><td>&amp;cc=support@yourcompany.com<\/td><\/tr><tr><td>bcc<\/td><td>BCC recipient<\/td><td>&amp;bcc=archive@yourcompany.com<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<p class=\"wp-block-paragraph\">You can add several addresses separated by commas. And the order of the parameters doesn&#8217;t matter, as long as the first one goes after &#8220;?&#8221; and the rest after &#8220;&amp;&#8221;.<\/p>\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-anatomia-enlace-1024x576.png\" alt=\"Anatomy of a mailto link: address, subject, CC and message body\" class=\"wp-image-107700\" srcset=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-anatomia-enlace-1024x576.png 1024w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-anatomia-enlace-300x169.png 300w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-anatomia-enlace-768x432.png 768w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-anatomia-enlace-1536x864.png 1536w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-anatomia-enlace-110x62.png 110w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-anatomia-enlace-60x34.png 60w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-anatomia-enlace.png 1672w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n<div class=\"wp-block-group has-very-light-gray-background-color has-background\" style=\"border-radius:8px;padding-top:24px;padding-right:28px;padding-bottom:24px;padding-left:28px\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Add contact links to your newsletters<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Create campaigns with buttons, links and automatic unsubscribes in Mailrelay&#8217;s free account.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button is-style-mailrelay-primary-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/mailrelay.com\/en\/signup\/?utm_medium=cta&amp;utm_campaign=mailto\">Create a free account<\/a><\/div>\n<\/div>\n<\/div><\/div>\n\n<h2 class=\"wp-block-heading\">How do you write spaces and line breaks?<\/h2>\n\n<p class=\"wp-block-paragraph\">A link can&#8217;t contain spaces or special characters as they are. You need to write them encoded:<\/p>\n\n<ul class=\"wp-block-list\">\n\n<li>Space: <strong>%20<\/strong><\/li>\n\n\n\n<li>Line break: <strong>%0D%0A<\/strong><\/li>\n\n\n\n<li>&#8220;&amp;&#8221; sign within the text: <strong>%26<\/strong><\/li>\n\n\n\n<li>&#8220;?&#8221; sign within the text: <strong>%3F<\/strong><\/li>\n\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Accented letters and characters such as &#8220;\u00f1&#8221; usually work in modern email programs, but the safest option is to encode them too. For example, &#8220;informaci\u00f3n&#8221; is written <strong>informaci%C3%B3n<\/strong>.<\/p>\n\n<h2 class=\"wp-block-heading\">How do you create a mailto link in HTML?<\/h2>\n\n<p class=\"wp-block-paragraph\">In HTML you use the usual link tag, with mailto in the href attribute:<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>&lt;a href=&#8221;mailto:hello@yourcompany.com?subject=Information&#8221;&gt;Contact us&lt;\/a&gt;<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">In WordPress you don&#8217;t need to touch any code. Select the text, click the link button and type <strong>mailto:<\/strong> followed by the address. It works the same way in most email editors.<\/p>\n\n<h2 class=\"wp-block-heading\">Mailto examples to copy<\/h2>\n\n<p class=\"wp-block-paragraph\">Replace the address and the text with your own:<\/p>\n\n<ol class=\"wp-block-list\">\n\n<li><strong>Simple contact:<\/strong> mailto:hello@yourcompany.com<\/li>\n\n\n\n<li><strong>With subject:<\/strong> mailto:hello@yourcompany.com?subject=Quote%20request<\/li>\n\n\n\n<li><strong>With subject and text:<\/strong> mailto:hello@yourcompany.com?subject=Appointment&amp;body=Hi,%20I%20would%20like%20to%20book%20an%20appointment%20for<\/li>\n\n\n\n<li><strong>With CC:<\/strong> mailto:sales@yourcompany.com?cc=management@yourcompany.com&amp;subject=Order<\/li>\n\n\n\n<li><strong>To unsubscribe by reply:<\/strong> mailto:unsubscribe@yourcompany.com?subject=UNSUBSCRIBE<\/li>\n\n<\/ol>\n\n<h2 class=\"wp-block-heading\">What are its advantages and disadvantages?<\/h2>\n\n<p class=\"wp-block-paragraph\"><strong>Advantages.<\/strong>  It&#8217;s easy to create, needs no forms or coding, and the user writes from their own email account. Plus, filling in the subject helps you sort the messages you receive.<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Disadvantages.<\/strong>  If the user doesn&#8217;t have an email program set up, it doesn&#8217;t work. And the address is visible in the page&#8217;s code, so spam bots can harvest it.<\/p>\n\n<p class=\"wp-block-paragraph\">That&#8217;s why many websites combine a mailto link with a contact form and hide or encode the address. If what you want is to collect contacts for your list, the right option is a <a href=\"https:\/\/mailrelay.com\/en\/glossary\/subscription-form\/\">subscription form<\/a>.<\/p>\n\n<h2 class=\"wp-block-heading\">Can you use mailto in an email?<\/h2>\n\n<p class=\"wp-block-paragraph\">Yes, and it&#8217;s very useful. In a newsletter you can add a &#8220;Take this survey&#8221; button that opens an email with the subject already filled in. Or a link to book an appointment, request a quote or contact a sales rep.<\/p>\n\n<p class=\"wp-block-paragraph\">That said, a mailto link doesn&#8217;t replace the unsubscribe link in your campaigns. The law requires a simple, free way to unsubscribe, and an <a href=\"https:\/\/mailrelay.com\/en\/glossary\/email-marketing-tool\/\">email marketing tool<\/a> includes it automatically in every send.<\/p>\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-o-formulario-de-contacto-1024x576.png\" alt=\"Mailto or contact form: the advantages of each option\" class=\"wp-image-107704\" srcset=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-o-formulario-de-contacto-1024x576.png 1024w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-o-formulario-de-contacto-300x169.png 300w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-o-formulario-de-contacto-768x432.png 768w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-o-formulario-de-contacto-1536x864.png 1536w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-o-formulario-de-contacto-110x62.png 110w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-o-formulario-de-contacto-60x34.png 60w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/mailto-o-formulario-de-contacto.png 1672w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n<h2 class=\"wp-block-heading\">How Mailrelay helps you<\/h2>\n\n<p class=\"wp-block-paragraph\">In Mailrelay&#8217;s editor you can add mailto links to text and buttons, just like any other link. That way your subscribers can write to you with one click from the newsletter.<\/p>\n\n<p class=\"wp-block-paragraph\">Each campaign also includes its automatic unsubscribe link and a record of unsubscribes, so you don&#8217;t have to manage them by hand. And the statistics show you which links get the most clicks (on the free account and on Enterprise).<\/p>\n\n<p class=\"wp-block-paragraph\">The free account lets you send up to 80,000 emails a month to 20,000 contacts, with human support on every plan.<\/p>\n\n<div class=\"wp-block-group has-very-light-gray-background-color has-background\" style=\"border-radius:8px;padding-top:24px;padding-right:28px;padding-bottom:24px;padding-left:28px\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Let your subscribers write to you with one click<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Up to 80,000 emails a month for free, with human support on every plan.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button is-style-mailrelay-primary-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/mailrelay.com\/en\/signup\/?utm_medium=cta&amp;utm_campaign=mailto\">Try Mailrelay for free<\/a><\/div>\n<\/div>\n<\/div><\/div>\n\n<h2 class=\"wp-block-heading\">Frequently asked questions about mailto<\/h2>\n\n<p class=\"wp-block-paragraph\">These are the most common questions when creating a mailto link.<\/p>\n\n<h3 class=\"wp-block-heading\">What does mailto mean?<\/h3>\n\n<p class=\"wp-block-paragraph\">Mailto is short for &#8220;mail to&#8221;. It&#8217;s the prefix of a link that opens a new email addressed to a specific address.<\/p>\n\n<h3 class=\"wp-block-heading\">How do I add a subject to a mailto link?<\/h3>\n\n<p class=\"wp-block-paragraph\">Add <strong>?subject=<\/strong> after the address and write the subject with spaces as %20. For example: mailto:hello@yourcompany.com?subject=Website%20question.<\/p>\n\n<h3 class=\"wp-block-heading\">Why isn&#8217;t my mailto link working?<\/h3>\n\n<p class=\"wp-block-paragraph\">The most common reason is that the user doesn&#8217;t have an email program set up, or that the link has unencoded spaces. Also check that the &#8220;?&#8221; sign before the first parameter isn&#8217;t missing.<\/p>\n\n<h3 class=\"wp-block-heading\">Can a mailto link open Gmail?<\/h3>\n\n<p class=\"wp-block-paragraph\">Yes, if Gmail is set as the default email handler in the browser. Chrome allows this from Gmail&#8217;s settings.<\/p>\n\n<h3 class=\"wp-block-heading\">Is it safe to put my email address in a mailto link?<\/h3>\n\n<p class=\"wp-block-paragraph\">The address is visible to bots that harvest email addresses, so it may get more spam. Use a generic address, such as info or hello, and a good antispam filter.<\/p>\n\n<h2 class=\"wp-block-heading\">Related entries<\/h2>\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/email\/\">Email<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/email-address\/\">Email address<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/cc-and-bcc\/\">CC and BCC<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/email-subject-line\/\">Email subject line<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/call-to-action-cta\/\">Call to action (CTA)<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/subscription-form\/\">Subscription form<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/newsletter\/\">Newsletter<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/antispam-filters\/\">Antispam filters<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/email-signature\/\">Email signature<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/landing-page\/\">Landing page<\/a><\/li>\n<\/ul>\n","protected":false},"template":"","class_list":["post-107751","glossary","type-glossary","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Mailto: what it is, how to create a mailto link and examples<\/title>\n<meta name=\"description\" content=\"Mailto is the link that opens an email with the address already filled in.
