Postmark inbound alternative
ReceiveHQ is a Postmark inbound alternative for teams that need inbound email to webhook without US residency ambiguity. Keep your Postmark-shaped JSON handler — change MX to Germany, optionally drive setup from Cursor or Claude over MCP.

When teams leave Postmark inbound
Postmark’s inbound JSON webhook is polished. EU buyers leave when inbound is tied to outbound plans, hosting is US-centric, or they want agents to configure domains and read mail without a custom API client.
- Inbound-only pricing at €10 / 100k emails (or €100 / year)
- Hosted in Germany — see the hosting declaration
- Blackhole endpoints for MCP-first workflows (no webhook URL on day one)
JSON payload parity
Set the endpoint format to postmark. ReceiveHQ POSTs fields your handler already expects: From, FromName, To, OriginalRecipient, Subject, MessageID, TextBody, HtmlBody, Attachments, Headers, RawEmail, and more.
Full field tables: Webhook API docs.
Pricing contrast (approx.)
At ~100k inbound emails/month, Postmark Pro inbound overages dominate (inbound is not a flat inbound-only product). ReceiveHQ includes 100,000 emails for €10/month, then €10 per additional 100k. Always verify current Postmark list prices.
How to migrate
- Create an account on receivehq.com (or connect via MCP).
- Add your domain, create a webhook endpoint with Postmark format, point MX to
mx.receivehq.com. - Keep the same HTTPS URL and Basic auth your Postmark inbound used.
- Send a test message, confirm delivery in the console or via MCP.
