About Lettermint
Lettermint is a Dutch email delivery service built around transactional email, newsletters, and inbound processing, with every server hosted inside Europe. It positions itself as the EU partner for SaaS apps, e-commerce platforms, and product teams that need emails to arrive reliably without routing customer data through US providers.
The platform handles password resets, receipts, and notifications through a modern API and SMTP relay, adds broadcast campaigns for newsletters, and supports inbound email parsing for automated workflows. Multiple domains can be managed from a single account, with deliverability tooling, suppression lists, and detailed event logs.
Key benefits:
- Transactional email reliable delivery for critical product emails
- Broadcast campaigns newsletters and marketing sends from the same API
- Inbound processing parse replies and incoming mail into webhooks
- SMTP and API modern REST API alongside plain SMTP relay
- Multi-domain manage many sending domains in one account
Lettermint is operated from the Netherlands, and its sending infrastructure runs entirely within European datacenters. The service is GDPR-compliant, with a trust centre and data processing agreement covering EU regulatory obligations, making it a natural fit for European SaaS companies that need to keep customer email data out of US jurisdiction.
With a generous free tier of 300 emails per month and paid plans starting at €10 for 10,000 emails, Lettermint gives EU developers a privacy-respecting alternative to Postmark, SendGrid, and Mailgun without sacrificing modern tooling or pricing transparency.
Why choose Lettermint over Resend?
The decisive argument is data jurisdiction. Resend is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Lettermint removes that overhead. As a Netherlands-based provider, it operates under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
