Email Integration lists Postmark as one of the providers you can connect. Unlike SMTP providers, Postmark connects with a single API token instead of a host/username/password combination — a common choice when a customer specifically wants Postmark’s transactional-email deliverability (order confirmations, account verification, password resets, event signups) rather than a generic SMTP inbox.

​
Step 1: Get your Postmark API token

Sign up or log in at Postmark, then under Account Settings → API Tokens, generate a Server API token.
Postmark Server API Tokens page with the API Tokens tab selected and the Server API tokens value and Generate another token button highlighted
Email Profile modal with Postmark selected, Profile Name Postmark Email, Token field filled in, and Save button highlighted

​
Step 2: Add Postmark as an email provider

From Email Integration, click New, set Provider Type to Postmark, give the profile a name, and paste in the token. Click Save — the profile is now available anywhere Email Integration is used, e.g. the Email tab in Bot Settings, the same way as any other connected provider.
Postmark’s own dashboard also offers a Templates feature with dynamic variables (e.g. {{customer_name}}, {{order_number}}) for building the email itself on Postmark’s side. That’s a Postmark-account feature, independent of the profile you connect here — verify with your Postmark account whether you’re using their templates or ChatSyncs’ own Subject/Content fields (as in Bot Settings → Email) before assuming either is wired up.
