Note: Public domain emails such as Gmail and Yahoo can’t be used in Postmark. You can only use an email address from the domains you own (such as www.example.com).

Note: Sender Signatures are the “From” addresses that your subscribers see when they receive emails from you. Postmarks require signatures to be confirmed before you can send from them.

After clicking on the Create Sender Signature, you will receive a confirmation email. Click on the confirmation link in the email to verify the sender signature.

Note: To handle spam signups, all accounts in Postmark are put in Test mode by default. While your account is in test mode, you can only send and process 100 emails to sender signature email and other domains that you have verified. To increase the limit, you will need to request for Account approval.
