is an email delivery service with SMTP support. You can use it as your own SMTP server so that emails to subscribers are sent from your address instead of the default one. The setup works the same way for a status page and a release page.
So that your emails pass SPF checks and do not land in spam, the domain you send from must be delegated to Postwing. Follow the
guide. The sender address must be on that domain.
