Third-Party Services
Pro Mail SMTP connects to various third-party email service providers to send your WordPress site’s emails. When you configure and use these services, your site will transmit data to these external services. Below is information about each service:

This plugin does not collect or share any data with these services beyond what is necessary to send emails as per your configuration. Your email content and recipient information are only sent to the services you explicitly configure in the plugin settings.
