Email Finder by Name
Enter a person's name and company domain. The API tests every plausible email pattern via live SMTP and returns only the address that is confirmed deliverable. Pay nothing when no email is found.
What it does
Most email finders pull from a database of addresses collected months ago. emailfinder.dev works differently. When you request an email by name, it generates every plausible format for that person at that domain — first.last, f.last, firstlast, and more — then connects live to the company's mail server to find which one actually exists right now.
The result is a verified, deliverable email address — not a guess. If no format is confirmed by the mail server, the API returns not_found and you are not charged. Zero false positives, every time.
How it works
Enter name + domain
Provide the person's full name and their company domain. That is all you need.
API tests every pattern
The API generates all plausible email formats and connects live to the mail server via SMTP to test each one.
Returns the verified email
You receive only the address that the mail server confirmed as deliverable. If none verify, you pay nothing.
API endpoint
A single GET request with Bearer token authentication. Returns a JSON response in milliseconds.
Why SMTP verification matters
Email data decays fast. People leave companies, domains change, and mailboxes get deactivated. A database-driven finder returns whatever it stored the last time it crawled — which might be a year old. In independent testing, database providers return undeliverable emails 8–11% of the time.
Every bounce signals to your email provider that something is wrong with your sending behaviour. Enough bounces and your sender reputation drops — future emails, even to engaged contacts, start landing in spam.
emailfinder.dev connects to the mail server and confirms the mailbox exists before returning any result. By the time you have an email address, it is already verified deliverable. No separate verification step. No bounce risk from stale data.
Need more than name + domain?
emailfinder.dev has three other endpoints for when you have different input data.
- · LinkedIn Lookup — resolve a verified email from any LinkedIn profile URL.
- · Company Emails — return up to 20 verified emails at a company domain.
- · Decision Maker — find a contact by role (CEO, VP Sales, CTO) at any company.
Email finder by name — FAQ
How do I find someone's email by name?
The fastest method is to use emailfinder.dev's person endpoint: pass the full name and company domain, and the API verifies every plausible email pattern via SMTP and returns the confirmed deliverable address. Manual alternatives include guessing the pattern from a known example at the company, checking the person's LinkedIn contact info, or using a Google operator search like "firstname lastname" "@company.com" — but none of these tell you whether the address is currently active.
What information do I need to find an email?
The person endpoint requires a full name and a company domain (e.g. acme.com). You do not need an exact job title, employee ID, or any other data. If you only have a LinkedIn profile URL, use the LinkedIn lookup endpoint instead — it resolves directly from the profile without needing the domain.
How accurate is name-based email finding?
emailfinder.dev verifies every email via live SMTP before returning it, so the emails it returns have zero false positives — they are confirmed deliverable at the moment of the lookup. The API successfully returns a verified email for roughly 87% of lookups. When it cannot confirm an address, it returns not_found rather than guessing.
Is finding emails by name legal?
Finding publicly associated professional email addresses for legitimate business contact (sales outreach, recruiting, partnerships) is legal in most jurisdictions under GDPR, CAN-SPAM, and CASL, provided you have a legitimate interest, include opt-out options, and do not use the addresses in prohibited ways. You are responsible for complying with the applicable laws in your region and ensuring your outreach meets those standards.
How much does it cost?
The person email lookup costs 1 credit, starting at €0.009 per verified email on pay-as-you-go pricing. Credits never expire. You are only charged when the API successfully returns a verified, deliverable address — if no email is found, you pay nothing. Free credits are included when you sign up, with no credit card required.
