How we work

It is common for an email validation tool to make only one email delivery attempt to the tested address. Others just open a connection and don't deliver. When the server confirms the process, they disconnect.

Providers already understand this behavior and block those who try to adopt this practice.

SafetyMais has a much more intelligent process: we work with a multi-layer email verification algorithm, that is, several tests are performed on the same email address until its status is determined. If any of the test layers fail, the email will be invalidated.

SafetyMails has recognized quality

This can be proven through the awards we receive, customer testimonials and also by our participation in major business events related to email marketing.
