## What MailerSend is

MailerSend is the transactional product from the team behind MailerLite, and it inherits their strength: a drag-and-drop template editor good enough that a marketer can edit your receipt copy without a deploy. Around that it has a REST API, an SMTP relay, inbound routing, webhooks, activity tracking, and SMS. Its free tier was restructured in late 2025 and the current allowance is lower than it once was, so check their pricing page rather than an old blog post before you plan around it.

## Where MailerSend is the better choice

Pick MailerSend if someone other than a developer needs to edit transactional email. That is a real requirement in a lot of companies and their editor answers it well. It is also a good fit if you already use MailerLite for marketing and want the same vendor, the same billing, and one set of authenticated domains.

## Where emails.sh differs

We made the opposite bet about templates: the markup belongs in your repo, next to the code that sends it, reviewed in the same pull request and deployed with it. Around that, we compare on breadth of language clients, on inbound that stores and threads rather than routes, and on an integration path an assistant can complete because every page is markdown at the same URL and there is a skill it can install.

### Templates in your repo, not in a builder

Pass html and text on the send, or store a template and reference it by id. Your email markup lives in version control, gets reviewed, and ships with the release that changed it. If you would rather a non-developer edited it in a browser, take MailerSend instead. This is a genuine fork in the road.

### Nine maintained language clients

Node and TypeScript, Python, PHP, Ruby, Go, Rust, Java, .NET, and Elixir, plus curl, all with the same method names and error shapes. If your service is in Rust or Elixir you get a maintained client rather than an HTTP call you wrote yourself.

### Inbound that keeps the conversation

Inbound routing hands a parsed message to your endpoint. We store it, thread it against In-Reply-To and References, and let you reply through the same API, so the reply to a notification is part of a conversation rather than an event you have to persist.

## Moving from MailerSend

The API shapes are close. The work is deciding what happens to templates that currently live in their editor.

1. **Export the templates first** Anything edited in the MailerSend builder has to become HTML in your repo or a stored template here. Do this before you touch the send code, because it is the step that involves someone other than you.
2. **Swap the client** MailerSend takes from and to as objects with email and name, plus html and text, with a bearer token. Ours takes from as a formatted string, to as an array of addresses, and the same html and text fields. The personalization object becomes your own rendering or template variables.
3. **Re-verify the sending domain** Add the domain here and publish our DKIM and return-path records next to MailerSend's. Both can sign for the same domain during the overlap, and your reputation stays with the domain rather than with either provider.
4. **Move webhooks, then inbound** Repoint your activity webhook consumer at email.delivered, email.bounced, and email.complained and verify x-emailssh-signature. Change inbound routing last, because MX resolves to one provider and that switch cannot be staged by percentage.

## Side by side (checked July 2026)

| | emails.sh | MailerSend |
| --- | --- | --- |
| Pricing shape | Per email sent, in monthly volume bands. Domains, API keys, and seats are not billed separately. | Monthly plans by email volume, with SMS and extras priced separately. |
| Free tier | 3,000 emails a month, 100 a day, no card, sending from your own verified domain. | A free tier that was reduced in late 2025 and carries their footer. Check their pricing page. |
| Sending domains | One screen: add the domain, copy SPF, DKIM, and return-path records, watch them go green. Unlimited domains on every plan. | Domain verification with DKIM and SPF, with a clear setup flow. |
| Deliverability posture | Shared pools separated by send type, bounce and complaint tripwires below the thresholds that get senders suspended, dedicated IP on request. | Solid, backed by MailerLite's sending infrastructure. |
| Receiving mail | Inbound MX, parsed MIME, and In-Reply-To threading, so a reply arrives as part of a conversation you can query rather than as a raw webhook body. | Inbound routing to a webhook. Storage and threading are yours. |
| Logs and retention | Every message searchable in the dashboard and readable at GET /v1/emails/:id, with its delivery, bounce, and complaint events attached. | Activity view with per-message events, retained by plan. |
| Templates | Send html and text in the request, or store a template and reference it by id. No visual builder, because the markup belongs in your repo next to the code that sends it. | A drag-and-drop editor that is the standout feature of the product. |
| SDKs and frameworks | Nine clients (node and typescript, python, php, ruby, go, rust, java, .net, elixir) plus curl, and framework guides from Next.js to Laravel, Rails, and Django. | Official libraries for the mainstream languages. |
| Marketing and lifecycle | Audiences, segments, scheduled broadcasts, and automations, on the same verified domains and the same delivery log as your transactional mail, and on a reputation pool that is kept separate from it by force. | None. Their features index carries no audience or campaign product, and they direct marketing users to MailerLite. |
| Webhooks | email.delivered, email.bounced, and email.complained, each signed with x-emailssh-signature so you can verify the body before you act on it. | Signed activity webhooks across the delivery lifecycle. |
| Path for a coding agent | Every page served as markdown at the same path plus .md, an /llms.txt index of the whole site, and a Cursor and Claude Code skill you install once. | Clear human documentation. No installable assistant skill. |
| Support | Email support on every plan including the free one, answered by the people who wrote the API. We are small, and that cuts both ways. | Responsive, tiered by plan. |

## Questions

### Does emails.sh have a template editor?

No, and that is deliberate. You send html and text on the request or store a template and reference it by id, so the markup lives in your repo. If a marketer needs to change transactional copy without a deploy, MailerSend is the better answer.

### How is MailerSend related to MailerLite?

Same company. MailerLite is the marketing product and MailerSend is the transactional one, which is why the template editor is unusually good for a developer tool.

### What is MailerSend's free tier now?

It was restructured in late 2025 and the free allowance is smaller than the 3,000 a month it used to be, with a daily cap and their footer on messages. Check their current pricing page rather than any comparison post, including this one.

### Which has better inbound?

Different, not better. MailerSend routes an inbound message to your webhook. We store, parse, and thread it, and let you reply over the API. Routing is enough if you are forwarding; storage matters if the reply is part of your product.
