Frequently asked questions
How do Postmark message streams map to Mail.Land?
Use a transactional key (ml_pet_) for what you sent on your transactional stream and a marketing key (ml_pem_) for broadcasts. The key decides the stream, so there is no MessageStream field.
Can I keep using SMTP?
Yes. Point your application at smtp.mail.land on port 587 with STARTTLS and use a Mail.Land API key with SMTP enabled as the password.
Do I need to change my webhook endpoint?
Yes. Mail.Land sends different event names and signs every request with HMAC-SHA256, so your handler needs to verify the X-MLND-Signature header and read the new event names.
