Loops alternative
A European Loops alternative for transactional and marketing
Loops is a slick US product email tool, but it is US-hosted and send-only. PostStack gives you the same one-platform-for-transactional-and-marketing experience on EU infrastructure, with a real API, IMAP mailboxes, and lower pricing.
Why teams pick PostStack over Loops
EU data residency
Loops is a US company on US infrastructure, so EU customer data crosses the Atlantic and falls under the CLOUD Act. PostStack runs in Helsinki, Finland — GDPR compliance by default, not by add-on.
A real developer API
Loops leads with its visual editor; the API is secondary. PostStack is API-first — typed SDKs in TypeScript, Python, and Go, an MCP server for AI agents, and a full REST surface — while still shipping broadcasts and templates for marketing sends.
IMAP mailboxes built in
Loops is send-only. PostStack ships Dovecot IMAP/POP3 and webmail, so you can run real mailboxes on your domain alongside the API.
Per-email, not per-contact pricing
Loops bills on contacts, which gets expensive as your list grows even if you send rarely. PostStack bills per email sent, so a large dormant list costs nothing extra.

Frequently asked questions
Is PostStack a developer-first Loops alternative?
Yes. Where Loops centres the visual editor, PostStack centres the API — typed SDKs, an MCP server, and a full REST surface — while still shipping broadcasts, templates, and contacts for marketing sends. One platform for transactional and marketing, EU-hosted.
Why move from Loops to PostStack?
Three reasons: EU data residency (Loops is US-hosted), an API-first developer experience, and per-email pricing instead of per-contact billing that grows with a dormant list.
Does PostStack have a visual email builder?
Yes. PostStack ships a block-based visual builder with conditional content and dynamic merges, and the output is portable HTML so you can also hand-write templates or render them from code.
