Why is SMTP beneficial?

SMTP stands for Simple Mail Transfer Protocol. It's a protocol used in sending and receiving emails across the internet. It serves as the backbone of email communication, ensuring your messages reach their intended recipients efficiently and securely. You can integrate Zoho Campaigns Email API with your SMTP server to perform mail delivery tasks. There is no separate authentication mechanism for SMTP. The same token generated by OAuth 2.0 authentication can be used.

The main advantage of using SMTP integration is that it allows you to send mails from your own email clients or any SMTP sender to our SMTP server using the standard SMTP protocol, instead of using Zoho's REST API.
