Email Hippo dashboard Realtime ‘Verify Now’ results – one at a time

Top-level results give you a visual overview – the Email Hippo level of sendability and trust.

This easy-view scoring of four factors is reached by a point and weighting system that measures over

74 checkpoints and calculates whether the email address is genuine, and if you can trust it.

Can you send – should you send?

Behind each result is another, deeper, level of information, giving you the full low-down. More will tell you whether you can send to an email address – and also if you should send to it. That’s really clever.

Is the person you’re dealing with trying to hide their identity? Are they using a dark web address? Is it a spam trap? Is there a web domain associated with their email? What country is it registered in? More answers all these questions – and more.

Do you..

Sell data? The quality of your list can be a real advantage in a competitive market. More returns more accurate results than any other provider, so your data is worth more.

Perform email marketing? Bad email addresses on your database result in skewed marketing results, and sending to them wastes time and money. Accidentally sending to a spam trap can seriously harm your ability to connect with legitimate customers. More improves your deliver-ability rates and saves you time and money.
