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.
