FluentCRM uses the wp_mail() function to broadcast all the emails that is PHP-based mailer. There are various ways to deliver emails from WordPress. The SMTP Protocol, API-based 3rd party delivery providers, and direct PHP-based sending require SMTP Port 25 to be opened from the WordPress hosting server. Below is a screenshot of when no SMTP plugins are used on the website.

Hi Ivan, you can only setup bounce handlers for the SMTP providers we fully support. However, I’m taking this as a feature request so if we integrate with TurboSMTP, you will be able to handle bounce notifications.
