The speed of verification and the amount of verifications I can do makes this the best email verifier that you can find. It's super simple to use and it's now part of my day to day running of the business. Absolutely love it!

The email verifier is great. One of the best I've ever used (if notthe best). What I REALLY like is the Blaclist Shield. We're currently using 23 email sender addresses in campaigns, with around 15 of those addresses in use at any given time, and with almost all of them on permanent "warming". I was under the impression that everything was fine with these email accounts, with our warming tools providing insights and alerts about things like DKIM, SPF, and DMARC failures - or so I thought! I added all 23 sender accounts to Blacklist Shield and immediately saw warnings for almost every sender account, including two that were on blacklists. Blacklist Shield made it easy to identify, resolve and retest issues. It's a killer good tool.

How accurate it is which protects my domain reputation
