Why is my email not used as the sender address for emails sent by the app?
The sender email address will always be no-reply@edp-cdn.net to avoid the emails sent by the app from being delivered in the SPAM folder of your customers - especially when the emails contain some downloads. Our app email is verified with a very good reputation and is accepted by most mailboxes and that is why it is used for sending app emails. The email you enter into the app will however be used as the reply-to email address - it means that, if your customers reply to the emails sent by the app you are the one who will receive the reply.
If you really want to have full control on the emails sent by the app (including the sender email address), you can use your own SMTP server through services like Sendgrid or Mailgun. Once you have your SMTP details, you can enter them into the app from the Settings page > Expert features :
