To change the alias upon sending an email, click on 'SHOW' in the 'Sender' field. However, the main address of your Tutanota account (name in tab) will remain unchanged.

This will make your alias the default sender. You can change the default sending address to your own domain alias (or any other alias) by changing the default sender here in your mailbox→ 'Default Sender'. If you need more than five aliases, you need to buy a larger alias package here, even if the aliases are deactivated. When you are using your own domain with Tutanota, you can delete aliases with your custom email domain and create new ones. Deactivated aliases remain linked to your account in case you want to activate them again in the future. Please note: It is technically not possible to delete aliases created with a Tutanota domain. This can be any of the Tutanota domains or of your custom email domains that you have added to your Tutanota account. Click on the three-dot button to choose the domain for your alias. A pop-up opens where you can create the alias you want to add.

Go here in your mailbox→ 'Email aliases': Click on 'Show Email Aliases'. You can also switch to larger alias packages. If using any of the paid plans, you can add email aliases to your account.
