Brevo alternative
A developer-focused Brevo (Sendinblue) alternative
Brevo (formerly Sendinblue) is a marketing suite that ships SMTP and a transactional API as features. PostStack inverts the priorities — developer-first email API, with marketing tools sized to fit, on EU infrastructure.
Why teams pick PostStack over Brevo
Developer experience first
Brevo's product centre of gravity is the marketing dashboard; the API is a side-door. PostStack ships an SDK in TypeScript, Python, and Go, an MCP server for AI agents, and a typed REST surface as the headline.
Predictable per-email pricing
Brevo charges based on contacts and email-credits with confusing overlap. PostStack charges per email sent, with one number per tier and €0.25 per 1,000 overages.
IMAP mailboxes
Brevo is send-only. PostStack ships full IMAP/POP3 plus webmail.
Same EU, lower complexity
Brevo is EU-headquartered and uses EU data centres, so EU data residency is similar. The wins on PostStack are pricing, API ergonomics, and the developer toolchain.

| Brevo | PostStack | |

| Company HQ | France (EU) | Denmark (EU) |
| Where your email data lives | EU data centres | Helsinki, Finland — never leaves the EU |
| US CLOUD Act reach | No | No |
Brevo is genuinely EU-based — here PostStack wins on developer experience, IMAP mailboxes, and price rather than residency. Why EU hosting alone isn't enough →

Frequently asked questions
Is PostStack a Brevo replacement for marketing too?
PostStack ships broadcasts, contacts, segments, signup forms, and workflows — enough for an SMB marketing send. If you need a heavy CRM or multi-channel (SMS, WhatsApp), Brevo is broader.
How is PostStack different on day-to-day use?
You spend more time in the API and SDK and less time in a dashboard. The API is the product; the dashboard is for analytics and admin.
Why move to PostStack from Brevo?
Three reasons: simpler per-email pricing, an API and SDK that feel modern, and IMAP mailboxes integrated with sending on the same domains.
