Mailrelay Features

Mailrelay is an email marketing platform designed to create, send, automate, and analyze campaigns all from a single environment.

It stands out, above all, for combining an exceptionally high free volume with marketing features that cover the entire contact lifecycle.

With the free account, you can send up to 80,000 emails a month and manage up to 20,000 contacts, without entering a credit card.

Additionally, Mailrelay offers human support via phone, chat, and tickets for all accounts.

That significantly shifts the comparison with other email marketing tools.

It isn’t just about being able to send newsletters. Mailrelay includes automations, advanced segmentation, A/B testing, forms, landing pages, analytics, personalization, user permissions, and integrations.

Therefore, you can use it from the very first lead all the way to campaigns aimed at retaining, recovering, or converting customers.

Mailrelay for free: high volumes, contacts, and technical support

A free account to send up to 80,000 emails a month

One of Mailrelay’s main features is its ability to send mass emails with no upfront cost.

The free account allows you to send up to 80,000 emails a month to a database of up to 20,000 stored contacts.

Furthermore, it isn’t just a free trial that disappears after a few days.

The plan is permanently free and doesn’t require a credit card to get started.

This lets you test an email marketing strategy with a real database.

It also makes it easy to increase campaign frequency without hitting the limit after just a few sends.

The free volume is especially notable compared to other platforms:

• Mailjet currently offers 6,000 monthly emails and 1,000 contacts on its free account
• MailerLite limits its free plan to 2,500 monthly emails and 250 subscribers
• Klaviyo limits its free plan to 250 active profiles and 500 monthly email sends
• Acumbamail provides 2,000 monthly sends on its free plan.
• Mailchimp has also significantly reduced its free capacity, and its current offering operates at much lower volumes

As a result, Mailrelay’s 80,000 monthly sends make a massive difference among this group of competitors.

Easy contact import and export with no duplicates

Switching tools shouldn’t force you to rebuild your database.

That’s why Mailrelay lets you import contacts using CSV or TXT files, copy and paste data, and even migrate directly from Mailchimp.

During an import, Mailrelay identifies existing contacts.

Depending on your settings, it can ignore them or update their details, instead of creating the same contact all over again.

This makes it easier to work with large databases without generating duplicates with every import.

Exporting is also simple. You can filter subscribers and download the data as a CSV file to analyze it, create backups, or use it in other tools.

This simplicity reduces migration friction and gives you greater control over your audience data.

Mailrelay human support in Spanish

A good tool needs great features.

However, when a deliverability, DNS, or setup issue arises, having human help can be even more important.

Mailrelay offers human technical support via phone, chat, and a ticketing system, even on its free account.

Assistance is available in Spanish and other languages.

Therefore, you don’t need to upgrade to a paid plan just to ask a technician a question.

This difference becomes especially clear when comparing support models. For instance:

• Mailjet offers ticket support during the first 30 days of its free account
• Klaviyo limits free plan email support to the first 60 days
• MailerLite includes community support on its free tier and reserves other channels for paid plans

Thus, continuous human support is one of Mailrelay’s key selling points, especially for SMBs, associations, agencies, and teams without in-house email marketing specialists.

Email marketing deliverability and domain setup

High-deliverability email marketing with solid sending infrastructure

Sending thousands of emails doesn’t help much if a significant chunk ends up blocked or in the spam folder.

Mailrelay works with its own IP ranges and technologies designed to optimize mass email delivery.

The infrastructure and reputation of the sending system are a core part of its deliverability offering.

In shared IP environments, multiple senders use a common infrastructure.

This lets you leverage pre-warmed IPs with a strong reputation, rather than having to start from scratch with a new IP that has no history.

Furthermore, Mailrelay provides dedicated IP options for companies that need greater control over their sender reputation.

In that case, managing that reputation also depends much more heavily on the sender themselves.

Because of this, Mailrelay can adapt to both companies that prefer a shared infrastructure and those with highly specific sending needs.

SPF, DKIM, DMARC, and custom domains to improve deliverability

Deliverability doesn’t depend solely on the provider either.

Sender authentication plays a critical role.

Mailrelay lets you set up SPF, DKIM, and DMARC, even on the free account.

It also lets you use a custom domain to replace generic domains in tracking links and image URLs.

A custom domain reinforces consistency across your brand, the sender, and the links appearing in your campaigns.

This setup is specifically geared toward improving deliverability and how your emails are perceived.

Additionally, a single account can have multiple custom domains set up. This is incredibly useful when an organization works with several brands or authorized domains.

Thus, Mailrelay combines sending infrastructure with the tools every company needs to look after its own technical reputation.

Configurable open and click tracking

Not all companies want to track the exact same things. Nor do all campaigns need to measure the exact same data.

That’s why Mailrelay lets you toggle open and click tracking on or off from a newsletter’s advanced settings.

Users can decide whether to track clicks, opens, or both.

If you disable these options, Mailrelay stops collecting those metrics for that specific newsletter.

This capability gives you more control over your analytics and makes it easy to align each campaign with your organization’s internal privacy and tracking policies.

Advanced automation, personalization, and segmentation with Mailrelay

Email automation for drip campaigns, lead nurturing, and much more

Mailrelay features a visual automation editor to build journeys without needing to code them manually.

Flows can be triggered by a subscription, a specific date, a birthday, group or tag membership, and other events.

They also support conditions, splits, and a variety of actions.

This lets you create welcome campaigns, drip sequences, and lead nurturing strategies.

You can also set up reminders, lead magnet follow-ups, date-based automations, and birthday campaigns.

User actions can also be used as triggers.

For example, a click, a download, or certain contact updates can keep an automated journey moving forward.

For ecommerce, Mailrelay includes automations tailored to scenarios like abandoned carts. Plus, its system supports actions via email, SMS, and webhooks.

The advantage is clear: an SMB can automate standard processes without facing the learning curve of an overly complex platform.

Email campaigns with custom fields

Two contacts might belong to the exact same list yet still need completely different messages.

Mailrelay lets you create and store custom fields within subscriber records. Those details can then be used to personalize content and segment campaigns.

This means you can use data like their name, company, location, interests, or any other information your business has gathered.

Furthermore, Mailrelay lets you work with conditional content. Specific email sections can be shown or hidden based on the information available for each contact.

The result is a mass email that doesn’t have to look like an identical blast to your entire database.

Automatic tags based on contact behavior

Mailrelay tags allow you to represent interests, statuses, or stages within a funnel.

A tag can be assigned through a form or an automation. It can also change depending on what the contact does throughout their journey.

For instance, an automation can check if someone clicked a link. It can then apply a different tag to those who clicked versus those who didn’t.

These tags can later be used in filters, segments, and brand-new automations.

This way, every interaction provides insights to make your next communication even more relevant.

Advanced segmentation with multiple conditions

Mailrelay’s segmentation goes far beyond simply creating standalone lists.

Segments are dynamic. Contacts enter or leave them as they meet or fail to meet your conditions. Groups, on the other hand, function as more static clusters.

The builder lets you add multiple conditions and organize them into condition groups. Plus, you can decide whether all rules must be met or just a few of them.

You can even combine multiple groups using matching logic again. Therefore, you can build highly specific audiences without manually creating countless lists.

Conditions can be based on subscriber fields, groups, custom data, or behaviors. The latter includes opens and clicks.

For example, you could pinpoint contacts from a specific region, with a particular interest, who belong to a certain group, and who clicked on a specific campaign.

A/B testing to optimize email campaigns

Mailrelay includes A/B testing to compare different alternatives before sending out the final broadcast.

These tests let you experiment with elements like the subject line or the sender name and see which option delivers the best results.

The true value of A/B testing lies in replacing guesswork with hard data. A tiny tweak to your subject line can shift the response of thousands of recipients.

Additionally, having this feature right alongside segmentation, analytics, and personalization helps you build a process of continuous improvement.

Forms and landing pages to capture new contacts

Advanced opt-in form builder

Mailrelay includes a form builder that connects directly to your subscriber database.

When building a form, you can choose exactly which groups the new sign-ups will be saved to.

Those groups can remain visible or hidden from the user. You can also enable security measures like CAPTCHA.

The form supports custom fields and a range of design options. Elements can be rearranged and tailored to the exact information each business needs to collect.

You can also incorporate elements related to privacy policy acceptance.

This way, the lead drops directly into Mailrelay and can instantly trigger an automation flow without any manual processing.

Built-in landing page builder

Alongside its forms, Mailrelay features its own visual landing page editor.

You can start from a template or build the page from scratch. Then, simply drop in your opt-in form and publish the landing page to start capturing contacts.

The builder is fully integrated with Mailrelay.

Because of this, a newly registered user can flow directly into your contact database and continue along the journey you’ve set up for that specific lead magnet.

This is especially useful for ad campaigns, ebooks, webinars, promos, events, or any strategy built around a lead magnet.

Mailrelay also lets you work with custom domains, ensuring your brand presence doesn’t rely solely on the generic URLs assigned by the platform.

You can also configure subdomains via DNS.

Dozens of templates to build landing pages faster

Designing a page from a blank canvas isn’t always the most efficient approach.

Mailrelay includes a gallery of pre-designed landing page templates to serve as your starting point.

The lineup includes dozens of designs that can be adapted to various campaigns and goals.

You can then tweak text, images, sections, and forms to match the unique identity and offering of any business.

This cuts down the time it takes to go from a rough idea to an active lead generation campaign.

Email editor, templates, and professional campaign creation

Modular drag-and-drop editor with reusable blocks

Mailrelay’s editor lets you build emails using a visual drag-and-drop system.

Users can add text, images, buttons, dividers, and other elements without writing a single line of HTML. You can also work with pre-defined blocks and modular layouts.

One particularly useful feature is reusable blocks.

Mailrelay lets you save customized elements as favorites or universal blocks to reuse them in future designs.

This comes in handy for headers, calls to action, signatures, recurring promos, or corporate footers.

Consequently, your team doesn’t have to rebuild the exact same sections campaign after campaign. Plus, it maintains a much more consistent visual identity.

Hundreds of email templates to get started faster

Mailrelay offers an extensive gallery of email templates, featuring hundreds of options and designs that serve as a solid foundation for crafting professional campaigns.

These templates can be fully customized to match your corporate identity.

Mailrelay also lets you start from pre-designed layouts or use other methods to import your campaigns.

This benefits both those who want to design highly visual newsletters and those who prefer much simpler commercial messages.

Having ready-made templates slashes production time. Nevertheless, users still retain full ability to modify the structure using the visual editor.

AI-powered email copywriting

Mailrelay also incorporates artificial intelligence features right into the newsletter creation process.

The editor lets you use AI to help with your copywriting.

Furthermore, the tool can generate drafts based on inputs like a URL, the type of message, the tone, the language, and any specific prompts provided.

AI doesn’t replace a marketer’s strategy. However, it can drastically speed up drafts, variations, and first iterations of a campaign.

Combined with A/B testing, it also makes it easier to produce alternatives that can later be validated with real-world results.

Responsive design and dynamic content

Emails created with Mailrelay can be optimized to adapt to different devices.

This is crucial because the same campaign might be opened on a desktop, tablet, or mobile phone.

Additionally, the platform supports variables and conditional content.

For example, a section of your newsletter can be shown to certain contacts and hidden from others.

This lets you run highly personalized campaigns without having to build a completely separate email for every single segment.

Mailrelay analytics, users, and integrations

Real-time email marketing analytics and metrics

Mailrelay provides real-time statistics on the activity generated by your campaigns.

Available metrics include:

• Deliveries
• Opens
• Clicks
• Unsubscribes
• Spam complaints
• And bounces

Mailrelay also makes it easy to analyze which URLs are driving the most engagement.

Reports can display clicks using visual overlays and heatmaps.

Plus, you can easily distinguish between hard and soft bounces, unsubscribes, and spam complaints.

Mailrelay also provides extra data tied to opens and clicks, such as specific location details, browser type, and operating system.

Likewise, reports can be exported to CSV or PDF and shared via a private link.

Therefore, analytics aren’t just for casually looking at your results.

They help you decide which segments actually work, what content drives the most clicks, and which campaigns need a revamp.

Multiple users with profiles, roles, and permissions

Mailrelay is fully equipped to handle multiple users within a single account.

Each user can be assigned a profile with a specific permission level.

This way, a company dictates exactly who can edit newsletters, access analytics, build forms, or trigger sends.

Profiles allow you to grant or restrict highly specific actions.

Mailrelay features roughly a hundred possible permissions tied to tasks like reading, creating, updating, deleting, sending, sharing, or managing data.

For example, a designer might get access to the editor without seeing data they don’t need. Another user could analyze reports without holding the clearance to actually send an email.

This granularity is incredibly useful for marketing departments, agencies, and companies with strict internal approval workflows.

Mailrelay integration with Make.com

Mailrelay integrates smoothly with Make, an automation platform that lets you connect apps and shuttle data back and forth between them.

Through this pipeline, you can build scenarios that update subscribers, organize groups, sync contacts, or connect forms and outside apps straight to Mailrelay.

The practical utility is massive. A lead generated in a totally different tool can be automatically imported into Mailrelay and instantly receive the right tag or group assignment.

After that, an automation can kick off the appropriate follow-up sequence.

Plus, Make makes it easy to hook Mailrelay up with thousands of other services that power your broader sales and marketing workflows.

REST API, webhooks, and plugins to expand your integrations

Make isn’t your only integration route.

Mailrelay offers a REST API to work programmatically with contacts, campaigns, and other account data. It also features webhooks alongside various plugins and direct integrations.

For instance, there’s a dedicated WordPress plugin to sync users directly with Mailrelay. You’ll also find solutions tailor-made for ecommerce and other platforms.

This lets you deploy Mailrelay as a core piece of a much larger marketing stack, rather than keeping your data locked away in an isolated app.

Lead scoring, list cleaning, and advanced contact management

Database management involves a lot more than just creating groups.

Mailrelay’s current feature set includes contact scoring, automated imports, and automatic list cleaning, on top of dynamic segments, custom fields, and tags.

Lead scoring makes it easy to prioritize contacts based on the criteria you set within the platform. Meanwhile, maintaining database hygiene ensures you’re engaging with a highly responsive audience for your campaigns.

Likewise, groups, tags, segments, and fields can all be wired into automations. This transforms your database into an active engine that dictates exactly what messaging each person receives.

RSS campaigns, transactional email, and omnichannel communication

Mailrelay also packs in additional features that expand its utility well beyond standard newsletters.

The platform supports RSS campaigns, scheduled sends, transactional services via SMTP/API, and powerful automations featuring extra actions like SMS and webhooks.

Additionally, the current interface features dedicated areas for SMS and WhatsApp, right alongside traditional email campaigns.

The availability and pricing of specific channels or add-on services may depend on your chosen paid plan.

That’s why it’s important to distinguish them from the sending volume permanently included in the free email marketing account.

Mailrelay vs. Mailchimp, Brevo, Mailjet, MailerLite, Acumbamail, and Klaviyo

The market’s leading platforms share plenty of core features. Mailchimp, Brevo, Mailjet, MailerLite, Acumbamail, and Klaviyo all offer varying combinations of visual editors, templates, automation, segmentation, forms, analytics, and integrations.

Because of this, simply comparing a checklist of “yes” or “no” boxes can be highly misleading.

The real question is what exactly you can do, with how many contacts, how many sends, and on which specific plan.

With Mailrelay, this combination is exceptionally competitive.

You can bundle 80,000 monthly emails and up to 20,000 contacts with automations, A/B testing, segmentation, forms, landing pages, personalization, and robust analytics—all inside an entry-level tier with absolutely no monthly fee.

Mailjet

It provides an advanced editor, basic analytics, and forms on its free plan.

However, that tier is capped at 6,000 monthly emails, a strict 200 per day, and just 1,000 contacts. True segmentation only unlocks on their premium tiers.

MailerLite

It includes campaigns, three automations, a single landing page, three forms, and two users on its free plan.

However, its current limit sits at 250 subscribers and 2,500 monthly emails. Its free support relies entirely on community forums.

Klaviyo

It shines specifically in ecommerce, automation, segmentation, and analytics. Its free tier lets you test-drive these features, but strictly limits you to 250 active profiles and a mere 500 emails a month.

Free email support also comes with a hard 60-day expiration date.

Brevo

It features campaigns, a drag-and-drop editor, automations, and omnichannel communication.

Its free plan imposes a strict 300 daily email cap, meaning any true mass-sending strategy hits a severe volume bottleneck right out of the gate.

Acumbamail

It shares key advantages with Mailrelay for the Spanish market, such as Spanish-language support, automation, visual editors, and landing pages.

However, its own recent data places its free email capacity at around 2,000 monthly sends.

Mailchimp

It continues to offer a massive ecosystem of email marketing, forms, landing pages, automation, and integrations.

Nevertheless, its current free limits fall drastically short of the 80,000 sends and 20,000 contacts available right out of the box with Mailrelay.

Because of this, Mailrelay’s primary competitive strength doesn’t rest on one isolated feature.

Its true edge lies in bringing together the bulk of standard professional features with a free volume that towers over these competitors, backed by human support from the very first tier.

For an SMB, startup, association, creator, ecommerce brand, or agency, this means being able to build out a complete strategy long before database growth forces you into a paid plan.
