Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site.

Overview
About this plugin
Truelist Email Validator connects your WordPress site to the Truelist email validation API. It checks every email address submitted through your forms before it enters your database — blocking invalid, disposable, and fake addresses at the point of entry.
Invalid emails — addresses that don’t exist or have bad syntax
Disposable emails — temporary addresses from throwaway services
Role addresses — generic addresses like info@, admin@, support@
Failed MX check — domains with no valid mail server
Non-existent mailboxes — addresses where the mailbox doesn’t exist
Failed SMTP check — addresses rejected by the mail server
Bad syntax — addresses that don’t follow email formatting rules

External Services
This plugin connects to the Truelist email validation API to check whether email addresses are deliverable. This service is required for the plugin to function.
What data is sent: The email address submitted through your form is sent to the Truelist API for validation.
When it is sent: An API request is made each time a user submits a form with an email field. Results are cached for 24 hours — repeat submissions with the same address do not trigger a new API call.
