ZeroBounce’s real-time Email Finderⓘ API allows you to find emails by domain or name automatically. Add the API wherever you store contacts, and start searching today!
*Free account signup required. All users
get 10 free Email Finder queries monthly.
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.
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.
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.
Add the email lookup API to any website or CRM where you store your contacts and prospects.
Use our defined parameters to share your list of names and domains with ZeroBounce. Then, the email retrieval API will append valid email addresses to each entry where possible.
Who has time to keep searching? The Email Finderⓘ API lets you automate the entire email-finding process so that your new contacts always have a valid address. Set it, and forget it!
Gather a list of email and company domains to start your next email search. The bulk email lookup API will look for and test possible domain patterns and provide you with the address structures most likely in use.
