Automatically Remove Hard Bounces, Fakes, and Misspelled Emails From Your Email Lists

Connect your email service provider and mailfloss automatically removes invalid email addresses so the emails you send get in front of more ideal customers

Fake emails in your list hurt your business.

When you send emails to fake email addresses you get penalized. That means more of your emails end up in spam and less in the inbox of your real customers.
