Settings For Your Email Programs (IMAP & POP3)

You can use your 1&1 IONOS email address with any email program. Simply enter your email credentials and 1&1 IONOS email server settings in the program of your choice.

You should Create a 1&1 IONOS Email Address in 1&1 IONOS first, if you have not done so already.

Please note: Many email programs automatically detect your email server details and complete the setup without having to enter the data manually. It is suggested not to manually enter the server settings or adjust them unless you have problems sending and receiving emails.

Choice of account type

When setting up the account in your email program, you can set up the account using either IMAP or POP. We recommend using IMAP.
