Mailrelay integrates email, SMS, and WhatsApp on a single platform.<\/strong><\/p>\n\n Thanks to these channels, you can reach the vast majority of customers, covering the most widely used forms of digital communication.<\/p>\n\n Such as newsletters<\/a>, promotions, bulk SMS<\/a>, WhatsApp notifications, and much more.<\/p>\n\n The best part about these tools?<\/strong><\/p>\n\n You’ll have access to statistics<\/a> to track effectiveness at all times.<\/p>\n\n \u00bfQu\u00e9 otras funcionalidades <\/a>apoyar\u00e1n a estas campa\u00f1as?<\/strong><\/p>\n\n Beyond simply sending and analyzing these campaigns, there are other features that can help you, such as:<\/p>\n\n So that your communication with customers reaches them wherever they are.<\/strong><\/p>\n\n <\/p>\n\n Email remains the preferred channel for business communications in most companies. <\/p>\n\n For an SME, email marketing is essential. <\/strong><\/p>\n\n It lets you send newsletters, personalized offers, and updates directly to your customers’ or subscribers’ inboxes. <\/p>\n\n What should you expect from email marketing software?<\/strong><\/p>\n\n A tool like Mailrelay helps you handle multiple tasks with your contacts:<\/p>\n\n This keeps your contact list in perfect shape, which helps your sender reputation.<\/a><\/p>\n\n Mailrelay has a drag-and-drop editor that lets you create beautiful emails in minutes, with no effort.<\/p>\n\n You can find more information in this article<\/a>.<\/p>\n\n You don’t need any design experience \u2014 just drag the different elements wherever you want them.<\/p>\n\n Ready-made templates are also included, along with the option to use the built-in AI to create a template for you.<\/p>\n\n All options that will save you time.<\/p>\n\n Insert personalized content using variables or custom fields to make your emails unique for each recipient.<\/p>\n\n You could show the recipient’s name, or even make a section visible or not based on a contact field.<\/p>\n\n You can schedule when sends will happen and segment which contacts receive them, to ensure maximum effectiveness.<\/p>\n\n Having automations (autoresponders and automation workflows) can save a lot of work by sending emails based on contacts’ actions.<\/p>\n\n Such as subscribing, opening an email, or clicking a link.<\/p>\n\n Automating these actions lets you scale your email marketing.<\/strong><\/p>\n\n Email marketing is one of the online marketing tools with the highest return on investment (ROI<\/a>). In fact, if you use Mailrelay’s free account, the return is total \u2014 pure profit.<\/p>\n\n And as always, measurable.<\/strong><\/p>\n\n Email marketing can be perfectly complemented with bulk SMS campaigns.<\/p>\n\n Mailrelay lets you create SMS campaigns very easily:<\/p>\n\n Even with tracking and custom variables!<\/strong><\/p>\n\n You’ll be able to create unique SMS messages!<\/p>\n\n What can you use SMS campaigns for?<\/strong><\/p>\n\n For example, you can send a time-limited discount code via SMS, so it reaches your customers and contacts as quickly as possible.<\/p>\n\n You can even combine an email campaign with an SMS one, offering the same discount to maximize your reach.<\/p>\n\n Ideal for reminding customers about appointments, offers to specific contacts, delivery notices, order confirmations, or other types of alerts.<\/p>\n\n For this kind of transactional SMS, you can use the API.<\/a><\/p>\n\n With Mailrelay you can send both email and SMS campaigns, view their statistics, and analyze results.<\/p>\n\n In fact, you can turn a regular newsletter into an SMS campaign from the newsletter’s “show” option:<\/p>\n\n This conversion will create an SMS campaign for you:<\/p>\n\n You can edit this message however you like.<\/p>\n\n Notice that it also includes an unsubscribe link.<\/strong><\/p>\n\n In Spain, WhatsApp has become a key channel for both personal and professional use. <\/p>\n\n Many SMEs already use it to chat with customers, resolve questions, and even close sales quickly. <\/p>\n\n That’s why WhatsApp marketing is another channel added to Mailrelay.<\/strong><\/p>\n\n Mailrelay lets you send WhatsApp Business campaigns in bulk. <\/p>\n\n What does this mean? <\/strong><\/p>\n\n Basically, you’ll be able to send WhatsApp messages to contacts who’ve given you permission, using templates approved by WhatsApp (required for commercial sends). <\/p>\n\n These messages can include text, links, and even images or PDFs, giving you a very rich way to reach customers.<\/p>\n\n For example, below you can see the WhatsApp template editor:<\/p>\n\n Mailrelay offers the option to create WhatsApp campaigns in a way very similar to email campaigns. <\/p>\n\n You write your message (following WhatsApp Business policies), select the recipient list, and schedule the send. <\/p>\n\n Everything is managed from the same panel where you control your emails and SMS<\/strong>. <\/p>\n\n This gives you a unified view of your communication with customers.<\/p>\n\n One of Mailrelay’s most interesting features would be automations.<\/p>\n\n They let you communicate with your customers and contacts based on their own actions.<\/p>\n\n Let’s look at some examples: For example, when someone subscribes to your newsletter<\/a>, you can start sending a series of emails.<\/p>\n\n For example, an introduction, followed by a series of emails over the following days.<\/p>\n\n Since it’s automated, every contact who signs up would receive it.<\/p>\n\n Similar to the previous point, but not specifically after sign-up.<\/p>\n\n You can create a series that sends useful content, such as tutorials, case studies, guides, etc.<\/p>\n\n The best part is that with Mailrelay you can add conditions to these emails:<\/p>\n\n And with that information, split the flow into two paths \u2014 whether they meet the condition or not \u2014 giving you more flexibility.<\/p>\n\n For example, if a subscriber clicks a specific link in your newsletter showing interest in a certain product, the system can move them to a special group.<\/strong><\/p>\n\n And that’s not all \u2014 it can also automatically send them another email.<\/p>\n\n Or an SMS!<\/strong><\/p>\n\n If you have an online store, you can integrate the WooCommerce platform to send an email to users who left products in their cart without buying. <\/p>\n\n That automatic reminder can encourage them to complete their order.<\/p>\n\n Automations let you combine channels within the same flow. <\/strong><\/p>\n\n For example, you can send an email, check whether it’s opened, and then send an SMS:<\/p>\n\n Mailrelay includes a very complete automation module, included in the free account.<\/p>\n\n You can try it with no limitations!<\/strong><\/p>\n\n In addition to contacting existing customers, businesses \u2014 big and small \u2014 need to capture new contacts.<\/p>\n\n Mailrelay lets you capture new contacts mainly in two ways:<\/p>\n\n This is the essential way to capture new subscribers.<\/p>\n\n You can create new forms in the Subscribers<\/strong> – Subscription forms<\/strong> menu.<\/p>\n\n Below you can see a simple form with a couple of fields:<\/p>\n\n This is a basic form, with the essential fields.<\/p>\n\n You can enhance it with many more options and add custom fields.<\/strong><\/p>\n\n That way you could get the contact data you need (to use it as custom fields<\/a>, for example).<\/p>\n\n In any case, this form lets you save contacts in the group you choose.<\/p>\n\n And from there, launch an automation, for example.<\/p>\n\n Landing pages are pages created with the goal of converting visitors into customers \u2014 or subscribers, in this case.<\/p>\n\n You can insert the forms we mentioned in the previous point into these landing pages.<\/p>\n\n You can create these in the “Landing pages” menu of your Mailrelay account.<\/strong><\/p>\n\n You have a more complete article on the subject here<\/a>.<\/p>\n\n The landing page builder is very similar to the one for newsletters<\/a>, so it’s very easy to use.<\/p>\n\n These landing pages, just like forms, generate a URL you can share:<\/p>\n\n And that way, capture new contacts.<\/p>\n\n All the communication tools we’ve covered (email, SMS, WhatsApp) come with statistics so you can analyze your campaign results.<\/p>\n\n What statistics can you find in Mailrelay?<\/strong><\/p>\n\n Email is one of the channels that offers the most statistical information.<\/p>\n\n We already covered this in this article<\/a>.<\/p>\n\n You’ll have information, among other statistics, about:<\/p>\n\n With all this information, you’ll be able to improve your email campaigns based on data.<\/strong><\/p>\n\n For SMS campaigns, you’ll be able to see both the messages that have already been processed and those that have actually been delivered.<\/p>\n\n If you include links in your SMS, you’ll also see information about the clicks made.<\/p>\n\n For WhatsApp campaigns, you’ll see the following information:<\/p>\n\n You’ll also be able to see the conversations these messages have generated.<\/p>\n\n For the A\/B tests you run, you’ll also have information in their own section.<\/p>\n\n About which versions have more opens and clicks, so you can decide on the final version to send.<\/p>\n\n Both SMEs and large companies usually use other tools in parallel (for example, your WordPress website, an e-commerce platform, or a CRM to manage customers). <\/p>\n\n That’s why it’s essential for your communication software to integrate with your existing systems. <\/p>\n\n With Mailrelay, you have several integration options, including:<\/p>\n\n You can use the platform’s mailing infrastructure to send transactional emails or automatic notifications from your own applications. <\/p>\n\n Por ejemplo, podr\u00edas configurar Mailrelay como servidor SMTP de tu tienda online para que los emails de confirmaci\u00f3n de pedido salgan a trav\u00e9s de nuestros servidores (mejorando la entregabilidad y pudiendo registrar esas m\u00e9tricas en Mailrelay<\/a>).<\/p>\n\n It’s also useful for connecting web forms or internal systems<\/strong>, so that all your emails go out with the same high delivery rate.<\/p>\n\n Mailrelay has a powerful API<\/a>, which lets you integrate practically any service with Mailrelay (provided it also has one). <\/p>\n\n With the Mailrelay API, for example, you could automate contact syncing from your CRM: every time you add a new customer to your internal database, it’s automatically sent to a Mailrelay list for future campaigns. <\/p>\n\n Or vice versa, you could query a campaign’s results via the API from another application. <\/p>\n\n The possibilities are endless, and having a well-documented API guarantees you can adapt the tool to your business’s specific needs.<\/strong><\/p>\n\n With Make (which can connect to the Mailrelay API), you’ll be able to integrate hundreds of services with each other.<\/p>\n\n It’s a way to integrate Mailrelay without any technical knowledge.<\/p>\n\n Most businesses don’t want to spend a lot of time on training, so they don’t want complex tools.<\/p>\n\n They want the learning curve to be as smooth as possible.<\/p>\n\n That’s why we’ve designed the Mailrelay dashboard to be easy to use, with all the features grouped in the most logical way, so everything is easy to find.<\/p>\n\n Unlike many tools whose customer support is limited (or nonexistent on free plans), Mailrelay offers personalized support even with the free account. <\/strong><\/p>\n\n This includes phone support, live chat, and a help ticket system. <\/p>\n\n\n
