ℹ️ About SSL Certificates
SSL (Secure Sockets Layer) certificates encrypt data between your browser and mail.a1.net's server. A valid SSL certificate ensures that your connection is private and that you're communicating with the real A1 website.
Websites without valid SSL certificates may show browser warnings and are penalized in search engine rankings.
