How do I create a new email address as sender in my account?
The e-mail dispatch from MATE is carried out via the European cloud mail service Mailjet and its SMTP server.
The MATE Support Team will set up a new sender address for you.
You simply have to send us the desired e-mail address in writing and in the next step forward the verification e-mail from Mailjet to firstname.lastname@example.org so that we can finally set up the address.
