Postmark One-click Service

Last updated

Table of Contents

Postmark sends and receives transactional email for applications. The Postmark one-click service adds three records:

  • A DKIM record, with the hostname and value Postmark shows
  • A CNAME record for pm-bounces to pm.mtasv.net, Postmark’s Return-Path address for bounces
  • An MX record on the subdomain you choose, such as inbound.example.com, to inbound.postmarkapp.com for inbound email

The MX record is only on that subdomain, so it does not change where email for example.com goes.

Add the domain in Postmark first

Add the domain in Postmark, and note the DKIM hostname and value it shows. See Postmark’s guide to verifying a domain.
