Yes, it is possible to use your own SMTP server along with Chargebee.  

In order to integrate with a third-party SMTP service, you need to have the following details.

  • SMTP hostname
  • SMTP port number
  • SMTP username
  • SMTP password
  • Encryption type (SSL or TLS)

Just go to  Settings >> Customer-facing essentials >> Email notifications >> Change settings (under SMTP settings) >> Configure SMTP >> fill in the necessary details and click save.

You can find more about configuring the SMTP here.

Additional Information: Please make sure you subscribe to an encrypted and secure SMTP service in order to avoid any problems. Chargebee is not responsible if the third-party SMTP service gets compromised.
