Postmark is the email service that specializes on delivering transactional emails, which are emails expected by recipients: password reset emails, comment notifications, receipts, etc. Newsletters, announcements, or any other bulk email is not supported.
For your Postmark account, YAP ensures the following actions:
Send an email (send an email through the Postmark server that was verified with your X-Postmark-Server-Token)
Send an email with a template (send an email using a template associated with your Postmark account)
Before setup, check that you have granted to YAP the permission for sending notifications to your Postmark account. For this, sign in to Postmark and authorize the permissions requested by YAP.
To connect to your Postmark account, YAP requires your X-Postmark-Server-Token. Please paste the token from the Postmark Server, for which you'd like to perform this action.
