How to connect WordPress to Postmark

Postmark is a strong choice for transactional email such as password resets, account verification, order messages and security codes. Titanium Mail SMTP connects to Postmark through its email API, so you need a verified sender or domain and a Server API Token.

Postmark setup step by step

  1. In Postmark, create or open the server that will send email for this website.
  2. Verify the From email address or, preferably, the whole sending domain.
  3. Copy the Server API Token. Do not use an account-level token.
  4. In Titanium Mail SMTP, select Postmark and enter the token, From email and From name.
  5. Leave Message stream as outbound unless you created and intentionally use another transactional stream.
  6. Save the settings, then open Tools → Test Email and send a test to an address you can check.

Start with one reliable connection, then add complexity only when the site needs it.

The Free version covers popular providers, a Primary Connection, one Additional Connection, visual AND/OR Smart Routing, real test emails, simple failure alerts and supported WP Mail SMTP primary migration. Pro adds unlimited connections, backup delivery, automatic retry, full email logs, source detection, resend tools, protected alerts and visual scheduled reports.
