To send mail through your free GMX Mail account, you have to set it up first with the proper outgoing SMTP (simple mail transfer protocol) server settings. These settings are typically filled in automatically through the email client, but if they are not, you need to enter them.

You can access your GMX Mail email account from any browser, but you might prefer to access it in a different email program for convenience. When this is the case, your email client needs to know how to access mail from your GMX Mail account, which is done through IMAP and POP3 server settings.

All email providers use SMTP server settings, but they aren't the same.

  • GMX Mail SMTP username: your full GMX Mail email address (example@gmx.us)
  • GMX Mail SMTP password: your GMX Mail password
  • GMX Mail SMTP port: 587
  • GMX Mail SMTP TLS/SSL required: no

  • GMX Mail IMAP username: your full GMX Mail email address (example@gmx.us)
  • GMX Mail IMAP password: your GMX Mail password
