Last Verified June 2024

T-online.de supports IMAP / SMTP

This means you don't have to use T-online.de's webmail interface! You can check your email and send messages using other email programs (like Mailspring, Outlook Express, Apple Mail, or Mozilla Thunderbird). Using desktop email applications can improve your workflow. They typically offer more options, and your email is still available on your computer when you're disconnected from the internet.
