MailerSend

MailerSend — Transactional sibling of MailerLite, bootstrapped and cheap at mid volume. MailerSend is the transactional product from the team behind MailerLite, and it inherits that lineage: a genuinely good drag-and-drop template builder, clear analytics, and pricing that gets attractive between 50,000 and a million messages a month. Approval of new accounts is manual and can take a day. The free tier has been cut over time, so treat the current allowance as a floor rather than a promise. Built by MailerLite. Founded 2020. Bootstrapped.

We track it in 1 comparison — Email APIs — so every claim below is a cell in a table you can open and check rather than an impression. Across those rosters it sits against 12 other tools, and what follows is where it visibly separates from them.

Where it wins.

• React Email / MJML — handlebars, mjml, tied for best across 3 of 12 tools.
• BIMI — Yes, which only 3 of 11 tools here manage.

Each of those is ranked against the whole roster on its category page, not against a hand-picked subset, so a first place here means first of everything we list.

Where it gives ground.

• Dedicated IP — $50 /mo, 5th of 7. Amazon SES records $24.95 /mo.

None of these disqualify it on their own. They are the fields to check against your own requirements before you commit, because they are the ones where a competitor genuinely does better.

Provenance. 23 of 25 tracked fields carry a value for MailerSend, and 0 of those cite a document you can open. Nothing here carries a verification date yet, which is itself a reason to check before committing. Every figure keeps its own provenance — measured by us, claimed by the vendor, inferred, or community-reported — and we would rather print a dash than a guess.

Its nearest neighbour in our data is AhaSend. MailerSend is ahead on Hosted templates (visual-editor against none) and Product scope (both against transactional-only). AhaSend takes llms.txt docs (Yes against No) and Time to first send (15 min against 1440 min). That pattern repeats across the rest of the roster — see MailerSend alternatives for the other rivals, each compared the same way.

The best price per message once you are past 50,000/month and want a real UI, undercut only by SES and the indies. The manual approval gate is the tax — fine if you are planning a migration, painful if you are shipping tonight.

MailerSend is the right call in these situations, each one drawn from a field we actually record:

• Mid-volume sending where SES is too raw and Postmark too dear.
• Non-engineers who need to edit templates.
• Teams already using MailerLite for marketing.
• React Email / MJML is your binding constraint. MailerSend records handlebars, mjml, the best figure in the Email APIs roster. We define that field as markup and templating systems with first-party support — a documented integration or native handling in the SDK.
• BIMI is your binding constraint. MailerSend records Yes, which only 3 of the 11 tools in the Email APIs roster do. We define that field as BIMI is DNS plus a VMC, so nothing truly blocks it.

Reach for something else when any of the following is a requirement rather than a nice-to-have:

• Dedicated IP. MailerSend records $50 /mo, 5th of 7 in the Email APIs roster. Amazon SES records $24.95 /mo on the same field. If that is a hard requirement rather than a preference, start elsewhere.

We publish this block because a comparison that only lists what a tool is good at is marketing. Every figure above sits on the same page as its source, and the field definitions are on the category tables if you want to check how we measured them.

What we don't know. 2 of the 25 fields we track for MailerSend are still blank: Throughput ceiling and MCP server. Those render as dashes rather than as zeroes or assumptions, because an empty cell and a bad cell are not the same thing and only one of them is honest. If you know any of these figures and can point at a document, tell us.
