Why choose ZeroBounce’s Email Finder API

Get accurate, validated emails

ZeroBounce’s email discovery API is the only Email Finderⓘ that provides you with valid emails. Every search occurs in real time and undergoes our robust email validationⓘ process to test possible patterns until you get a valid result.

Never pay for unknown results

Our email search API continues testing and validating possible patterns until it discovers a valid email address. If no valid address exists, we’ll let you know the cause (domain is disposable, a spam trap, contains an unroutable IP, etc.). For truly unknown results, you’ll never pay a credit.

Search with minimal data points

Our domain-based email API lets you search for possible email address patterns with just a list of domains. We’ll provide you with a confidence score for each pattern so that you can plug in names for that domain as you go. Add names to your Email Finderⓘ API search for even more accurate, validated results.

Frequently asked questions about Email Finder API

An email finder API is an application programming interface that allows your preferred database or CRM to communicate with the ZeroBounce platform to conduct email searches. You can use the Email Finder tool from anywhere by adding the API code to your preferred location and your ZeroBounce API key.

The domain-based email finder API uses a list of email and company domains to search for possible email address patterns used by that domain. Your results will include several possible patterns and a confidence score indicating how likely that pattern is currently in use.

A name-based email finder API uses a person’s name along with their company domain for a more in-depth email finder search. By testing the person’s name with possible email domain patterns, ZeroBounce can validate different email addresses until it discovers a valid result.

To set up the ZeroBounce Email Finder API, you must add the API code to your website, or anywhere you store your contact data. When submitting a request, you must also add your unique ZeroBounce API key to connect with the ZeroBounce servers successfully. You can learn more about setting up the email search API by visiting

our documentation

.

The Email Finder API is free. However, you will need at least 20 credits to cover each valid result to perform an Email Finder search.
