Proofy

Proofy is an email verification tool that can help you improve your email deliverability by removing invalid and disposable email addresses from your lists. This can help you avoid bounces, improve your sender reputation, and get more of your emails delivered to the inboxes of your intended recipients. Proofy is easy to use and affordable. You can verify your email lists using our web app or API. We also offer a free trial, so you can try before you buy. It uses various methods to verify email addresses, including syntax checks, MX record checks, SMTP authentication, and catch-all address checks.

This ensures that you get the most accurate results possible. Proofy is constantly adding new features and improvements to its service. For example, the company recently added a new feature that allows you to verify email addresses against multiple sources.
