Your questions answered
Common questions
How accurate are the emails returned in the Domain Search?
The email addresses returned can have two different states:
- Verified email address: we were able to recently validate the email address is valid. You can recognize these email addresses with the green Verified icon next to them.
- Any other email address: these have not been fully verified recently, but are returned with a confidence score that evaluates the accuracy instead. This score considers all the signals we can get to provide a relevant evaluation (SMTP verifications, number and quality of sources, match with the most common pattern and other criteria). If relevant, a checkmark icon will let you manually trigger an email verification to get more insights.
Where does the data come from?
All the email addresses found in the Domain Search are returned with public sources on the web, along with their discovery dates.
How can I find someone's email address if I already have their name?
To find the email address from a full name and company name or website, you can use the Email Finder.
