About Email Hippo 

Email Hippo was established in 2000 as an email checking tool. Since then, we have experienced extraordinary growth and developed our fraud-proofing product, MORE, which combines email verification with extra checks that identify invalid and suspicious sign ups. In 2017, Email Hippo became the first company in the industry to receive international security accreditation ISO 27001.

Our company continued to go from strength to strength, and the joint focus on innovation and quality led to us receiving the most prestigious award for a UK company: a Queen’s Award for Enterprise. This award was specifically awarded for our innovation, particularly for our fraud prevention API and the Email Hippo Trust Score. 

Email Hippo is now much faster and provides more detailed results on a greater scale of delivery than anything imaginable in 2000. We have decades of specialist experience and a shared vision for delivering excellence and taking email validation into new applications.

What our clients say 

"We thoroughly compared the quality of numerous email verification vendors and selected Email Hippo. Vendor assessments are simple, but the value of a partnership takes time to develop. Over the years we’ve consistently been happy with the quality of service and responsive nature of Email Hippo."

Tony Karrer, Ph.D.

Founder & CTO


"We thought it would be cool to remove throwaway emails and deal with mistakes. It’s a super tool and it’s really good to see how many errors there actually are. If our emails are bad then our results aren’t so good and it’s not so easy for us to say for sure what the support is for our campaigns. We need our emails to be credible and influential. That’s why we’re happy with Email Hippo.”
