Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.6
GPA, above 16 of the 26 other email sending services we grade
Lettermint sends transactional email, newsletters and broadcast campaigns, and receives inbound mail, through an SMTP relay or a REST API. Plans differ by features and by how many sending domains they allow, and each paid plan includes 10,000 emails a month with overage billed per thousand. Its pricing page says email data is processed and stored only in the EU and that billing is in euros.
To get you started, here are 9 things to know about Lettermint, taken from its own pages and our grades.
You verify a sending domain with DNS records and wire up SMTP credentials or an API key before the first email goes out.

Best for EU-hosted transactional and broadcast email
Lettermint is an EU-hosted email service for transactional, broadcast and inbound mail through SMTP, an API and SDKs, from €10 a month for 10,000 emails. The free plan stops at 300 emails a month, and a dedicated IP is a €50 add-on for Pro customers only.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | €10 a month for 10,000 emails, at the cheaper end of a category whose cheaper quarter tops out at $10. |
| Free plan and trial | C | A free plan of 300 emails a month, 1 domain and 1 user with no card; a live app will pass that quickly. |
| Features | B | Transactional, broadcast and inbound mail in one account, SMTP and a REST API with SDKs, managed IP pools, suppression and a sandbox mode. |
| Ease of use | C | No store rating on record. You verify a sending domain with DNS records and wire up SMTP credentials or an API key before the first email goes out. |

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Lettermint you would be making mail servers with a good name among inbox providers. That is not a weekend's work, with an AI app builder or without one.
It costs $134.06 a year.
What you could not
- Mail servers with a good name among inbox providers.
- Newsletters sent to thousands of people that still reach the inbox.
- It plugs into other products, Laravel, Symfony Mailer and WordPress among them, and has an API.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Lettermint’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
