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.

Default SMTP Settings for GMX Mail Accounts

Before sending an email from your GMX account, you must enter the following information. It is probably already there, but you should confirm this anyway. If you have any problems with outgoing mail, start your troubleshooting here.

  • GMX Mail SMTP server address: smtp.gmx.com
  • 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 Default IMAP Settings

To access email sent to your GMX Mail account with another email program or service that uses the IMAP protocol, enter the following settings in the email program:

  • GMX Mail IMAP server address: imap.gmx.com
  • GMX Mail IMAP username: your full GMX Mail email address (example@gmx.us)
  • GMX Mail IMAP password: your GMX Mail password
  • GMX Mail IMAP port: 993 (alternative: 143)
  • GMX Mail IMAP TLS/SSL required: yes for port 993, no for port 143

GMX Mail Default POP3 Settings

To access email sent to your GMX Mail account with another email program or service that uses the POP3 protocol, enter the following settings in the email program:

  • GMX Mail POP server address: pop.gmx.com
  • GMX Mail POP username: your full GMX Mail email address (example@gmx.us)
  • GMX Mail POP password: your GMX Mail password
  • GMX Mail POP port: 995 (alternative: 110)
