What is an email verification tool & what does it do?

Email verification tools are services that essentially take lists of emails and determine which addresses are deliverable and undeliverable.

For example, if you take a list of 20 email addresses and upload it into a verification tool you'll get a report back of how many out of those 20 were deliverable, undeliverable, and risky.

Avoiding the undeliverable and risky emails is going to ensure your domain has the best email deliverability possible...aka the secret sauce to be positive your emails land in the inbox.

Should you need it, you can find our in-depth guide on why you need to check if email is valid.

ZoomInfo (good database)

email verification tool

Of course we had to mention this one, it's all the rage lately. Users are loving ZoomInfo because of its extensive database and all of its functionality.

The only downside to this is that it's not for the faint of heart. Some users have said that the user interface can be difficult to work with.

We tested ZoomInfo out for ourselves and got some great results! The interface wasn't as user -friendly as the other options, but once you start going you'll get a hang of it.

And the best part is that, like Dropcontact, it enriches your list! So we were able to find 36 more emails that otherwise would have been marked as undeliverable!

Note - ZoomInfo verifies emails with NeverBounce, so if you're looking for great email verification + enrichment..this is the platform for you!

ZoomInfo is best for:

  • B2B companies looking to contact C-suite execs (their database contains info for 4.3M+ c-suite level individuals)
