Emails sent from cPanel to Gmail can bounce for several reasons. Your domain may lack proper DNS records like SPF, DKIM, or DMARC. Gmail uses these to verify sender authenticity. Your IP address might be on a blacklist. A poor sender reputation can also cause Gmail to reject emails. Your email content may trigger Gmail's spam filters. A misconfigured cPanel server could result in delivery issues. Gmail might block your emails if you exceed their sending limits. You should check your server's configuration and domain authentication. Using an email deliverability tool helps you identify and resolve the issue effectively.

I think it is usually because Gmail is strict with email authentication. From my experience, emails sent from cPanel often bounce if SPF, DKIM, or DMARC records are missing or not set up correctly. Things that helped me were adding proper DNS records for authentication and making sure the sending domain has a good reputation. This makes Gmail trust your emails more and reduces bounces.
