Mailfra team

We're on a mission to fix cold email

Cold email is broken. Spam filters are smarter, inboxes are crowded, and getting through is harder than ever. We built Mailfra to change that.

Our Story

In 2021, our founders Cashe and Maryann were running a sales consulting agency. They watched their clients struggle daily with the same problem: emails weren't landing.

Deliverability was a black box. Tools were fragmented. And every month, more emails were hitting spam. They knew there had to be a better way.

So they built it. Mailfra started as an internal tool, then became a product, and is now the platform trusted by over 50,000 sales teams worldwide.
