Mail forwarding/POP3 (from other email accounts)
We understand that changing email providers is a tough thing to do, and we want to help ensure it is as easy as possible.
Most mail services have an email forwarding feature that allows your email from an existing account to be forwarded to your new Proton Mail account.
POP3 is another method often used to forward mail to new mail addresses. At this time Proton Mail does not offer POP3 services(new window).
