The possibility to create a scoring model to predict the best leads to pursue in the sales funnel.

We really love how user-friendly it is. The super simplified layout makes it really easy to navigate your way around the site and various tools, and the validation results in particular are very detailed and extremely useful to us. It's by far one of the best validation tools we''ve used - and we've used maaany over the years. It's the only tool we use for our client campaigns, and the only tool we recommend to industry peers. We love that you can validate a single email at the click of a button, as well as the speedy delivery of results - and it's free! Plus, there's no limit to how many emails you can validate. The blog resources are very insightful and useful. The branding is pretty fun too!

Being able to verify your list of emails helps with targeting the right group of users for ads, deliverability rates, etc.
