best reverse email lookup tools

Reverse Email Lookup is a process to identify who owns an email address and can be a great tool for B2B companies that already have a database of emails but don’t know who they are. There are many use cases of reverse email lookup, but these tools when used on a larger set of data work best.

There are free ways to reverse lookup on any email address, however, we won’t discuss them in detail in this article. Having tested many tools, with some being the real deal and others being junk, I will now come straight to some of the best tools available today.

Let’s get started!

5 Best Reverse Email Lookup APIs

Enrichment API

Yes, we are a little biased here keeping our reverse email lookup tool on the top. But there is a reason for that, we think that Enrichment API’s Reverse Lookup API is currently the best option available to reveal an identity behind an email address.

Why do we think so?

Enrichment API doesn’t use a database to fetch data, we do real-time enrichment of data, and thus every email you put up in the tool goes through a proprietary system we made and fetches real-time data associated with that email.

Well, you may think, what’s the problem with the data reverse email lookup tools can fetch from a database?

There isn’t any problem with that data too, but taking the freshness of data one step ahead and delivering the same to our customers by doing the whole process in real-time is what makes us different from others.

The API we made uses multiple approaches to find the data points relevant to that email address. Further, if you are a product manager, CEO, or Founder, you can quickly test our tool when you sign up.

Let me show you a quick demo of the tool for a single email address so that you can test it too.

You can sign up from here, and we offer 50 free credits for you to test it.

Here’s a video tutorial too.

The get_more_data parameter contains an API URL to EnrichmentAPI’s Person Enrichment API which can be used to get more detailed information about the person.

Our API also returns social links which are the related links to the person and is quite useful when you don’t have authentic information about the person.
