Settings for Your Email Program (IMAP & POP3)

You can use your 1&1 IONOS email address with any email program. Enter your access data and the settings of the 1&1 IONOS email server in the program of your choice.

An 1&1 IONOS email address that has already been set up is required.

Please note: Many email programs provide you with a setup wizard. As a rule, it is then no longer necessary to enter the data manually. Only check these if you have problems sending and receiving emails.

Choice of account type

When setting up the account in your email program, you can freely choose between IMAP or POP. Your mailboxes are automatically configured to use both account types. We recommend a setup via IMAP.
