Questions
What is a reverse email lookup?
A reverse email lookup starts from an email address and finds the person behind it. Instead of searching by name, you paste the address and get their name, current role, employer, location and professional background.
Is this reverse email lookup free?
Yes. You get 10 lookups free with no sign-up, and 20 more when you enter your work email. After that, create a free Crustdata account to keep going on your own credits.
How does it work?
The email is matched against Crustdata's person dataset, which covers hundreds of millions of professional profiles. When there is a match, you see the profile along with the full work history, education and skills. A no-match costs you nothing.
What do I get back?
Name, headline, location, years of experience, every role with its dates, seniority, location and job type, grouped by company, plus education, skills, languages and a link to the person's profile.
Why does it only take work emails?
Work emails map to a person and a company, which is what makes the match reliable. Personal addresses like Gmail are not supported here.
Can it find phone numbers or personal emails?
Not in this free tool. Create a free Crustdata account and spend credits on the Contact Enrich API or the playground to get work phones and personal emails.
Is reverse email lookup legal?
Looking up professional data is legal when used responsibly. You are responsible for following the rules that apply to your outreach, such as GDPR, CCPA and CAN-SPAM. People who have asked to be removed from Crustdata's data never appear here.
Reverse email lookup vs email finder: what's the difference?
A reverse email lookup starts with the email and tells you who it belongs to. An email finder starts with a name and company and tries to find the address. This tool is the first kind.
How accurate is it?
Each result carries a match confidence. Exact matches show at 100%. Between 70% and 90% the card gets a 'Likely match' badge so you can judge for yourself, and below 70% we show no match rather than guess.
