Tuta

What is Tuta?

It also offers custom email domains. A provider-owned address and a customer’s own domain should not be collapsed into the same account-policy rule.

How should you handle Tuta signups?

Verify ownership through the normal email flow and judge credit eligibility through account behavior.
