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 What other features will support these campaigns?<\/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 For example, you could set up Mailrelay as the SMTP server for your online store so that order confirmation emails go out through our servers (improving deliverability and letting you track those metrics in Mailrelay). <\/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
