Setting up Postmark

Postmark

Postmark is a reliable transactional email service focused on fast delivery and excellent deliverability. Kurrier connects directly to Postmark via its Server Token and Account Token for sending and managing outbound emails.


1. Overview

When you link Postmark to Kurrier, the app sends mail using Postmark’s REST API β€” no SMTP needed. You just need two keys from your Postmark dashboard:

  • Server Token β€” used to send emails from a specific Postmark Server
  • Account Token β€” used for administrative operations

2. Adding Postmark in Kurrier

In Kurrier, go to:

Dashboard β†’ Providers β†’ Add Provider β†’ Postmark

Enter the following fields:

FieldDescriptionExample
POSTMARK_SERVER_TOKENYour Postmark server API token74ef518e-2dfa-451d-b9cf-2843608f789a
POSTMARK_ACCOUNT_TOKENYour Postmark account-level token0762807c-08e9-4ac3-a872-25e635766g61

Click Submit to save your configuration. Kurrier will automatically validate the credentials and show βœ… Verified when successful.


3. Where to Find Your Tokens

  1. Log in to your Postmark Dashboard.
  2. Navigate to Servers β†’ (Choose your Server).
  3. Under API Tokens, copy the Server API Token β€” this identifies that specific sending server.
  4. For the Account Token, go to Account β†’ API Tokens and copy your account-level token (used for broader account access).

4. Verify the Connection

After saving, click Verify Connection in the Postmark card. Kurrier will test connectivity by making a simple authentication request to the Postmark API.

  • βœ… Success: You’ll see a verified badge next to your Postmark provider.
  • ⚠️ Failure: Check that both tokens are valid and belong to the same Postmark account.

5. Troubleshooting
