All email sent through WordPress sites are handled by a third-party email service that ensures the email is delivered successfully and performs anti-spam filtering. This helps prevent emails originating from your web server from being marked as spam or your web server from being blacklisted if a site on it begins to send spam emails.
Emails are actively filtered on the Pagely network. This helps prevent mass emails from non-WordPress sources – such as those sent via spammer tools, which attackers may have uploaded in the event of a compromise.
