What our awesome customers are saying

Brandon McDonald

Director, Demand Generation - Randstad USA

We were looking for an email validation service that could support enterprise level volume and tight integration with HubSpot, and frankly mailfloss was the only game in town.

mailfloss is literally the only piece of software that I use every single month that I don't even have to think about and I love that, because it's totally set and forget it. I love the simplicity.
