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.
Who Lettermint is for
- Fits if you need your mail data kept in the EU
- Works for small apps that fit in 10,000 emails a month
Who Lettermint is not for
- Tight if you stay free, since 300 emails a month, 1 domain and 1 user is the cap
- Watch out: prices are in euros and billed in euros
- Watch out: a dedicated IP is a €50 a month add-on, Pro only, from 300,000 emails a month
- Watch out: written SLAs and bring-your-own-IP are for enterprise customers on Pro
- Pricey if you go over your plan, at €1.10 to €1.50 per extra 1,000 emails
Why Lettermint gets a 2.6
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.

- CFree plan and trialA free plan of 300 emails a month, 1 domain and 1 user with no card; a live app will pass that quickly.
- BFeaturesTransactional, broadcast and inbound mail in one account, SMTP and a REST API with SDKs, managed IP pools, suppression and a sandbox mode.
- CEase of useNo 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.
- BPlatforms and integrationsA web dashboard and an API; the listing names Laravel, Symfony Mailer, WordPress, Node.js and PHP.

Keep Lettermint, or make your own?
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.
What is Lettermint?
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.
Worth knowing
