Setting Up Your "IONOS Mail" in Third-Party Applications


Integrating your IONOS email account with external email clients or software is straightforward. Follow these simple steps to get started. You will need your IONOS email credentials (address and password) for the configuration process.

Step-by-Step Guide to Configure Your IONOS Email

1) Open Your Email Client or Regzion Software

To begin, launch the email application or Regzion software where you'd like to add your IONOS account.

2) Input Your IONOS Email Credentials

Fill in the following details in the appropriate fields:

  • Email Address: Your full IONOS email address (e.g., youremail@yourdomain.com)
  • Password: The password associated with your IONOS email account (the same one used to access your IONOS webmail)
  • IMAP Server: imap.ionos.com
  • IMAP Port: 993
  • Encryption: SSL/TLS (This is the recommended security standard)
  • SMTP Server: smtp.ionos.com
  • SMTP Port: 465
  • Encryption: SSL/TLS (For secure email transmission)

3) Complete the Authentication Process

Once you've entered the required information, click the Login or Connect button (depending on your email client). This will trigger the authentication procedure to verify your credentials with IONOS.

4) Begin Using Your IONOS Email Account

After successful authentication, your IONOS account will be fully integrated, and you can begin managing your emails directly from your preferred email client or Regzion software.
