How It Works

From a Name to a Verified Email in One Request

The email lookup API combines pattern generation with real-time SMTP verification — so you only get addresses that actually exist.

1

Send Name + Domain

Pass a first name (or full name) and the company domain to the GET /api/v1/finder endpoint along with your API key.

2

Pattern Generation & Verification

The API generates up to 25 common email patterns (first.last, flast, first_last, etc.) and runs SMTP verification on each.

3

Verified Result Returned

The first confirmed deliverable address is returned as status: found with the email. If none verify, the response is status: not_found.

Capabilities

Why Teams Choose Our Email Finder API

A reliable find email address API needs more than pattern guessing — it needs live verification at the point of discovery.

25 Pattern Combinations

Covers the most common professional email formats to maximize the discovery rate across different company naming conventions.

Real-Time SMTP Verification

Every candidate pattern is confirmed against the mail server before being returned — no guesses, only verified addresses.

Company Domain Focus

Designed for professional domains. Free or public email domains are blocked to keep quality high and credits well-spent.

Clean JSON Response

Found addresses return {email, status:'found'}. Not-found cases return {email:null, status:'not_found'} — no ambiguity.

Predictable Credit Cost

Each finder request costs 10 credits regardless of outcome, making it easy to budget for large enrichment campaigns.

Shared API Key

One API key across all three EmailVerify.io APIs. Credits pool together and replenish automatically every month.

FAQs

Frequently Asked Questions

Question Icon

What is an email finder API?

An email finder API locates a professional email address from a person's name and company domain. EmailVerify.io's email finder API tests up to 25 likely combinations, validates each with MX, blacklist, and real-time SMTP checks, and returns the first verified address it finds — ideal for lead generation and outreach.

Question Icon

How does the email finder API work?

Send a GET request to https://app.emailverify.io/api/v1/finder with your API key, a name, and a company domain. The find email address API generates up to 25 combinations, runs MX, blacklist, and SMTP verification, and returns {"email":"[email protected]","status":"found"} or a not_found status if no valid address exists.

Question Icon

How accurate is the email finder API?

Every candidate address returned by the email lookup API is confirmed with MX, blacklist, and SMTP checks before being marked found, so you only receive deliverable, verified emails rather than guesses.

Question Icon

Is there a free email finder API?

Yes. New accounts include 10 free email finder queries plus 100 verification credits, no credit card required, replenished monthly. Each finder request uses 10 credits, so the free tier lets you trial the email finder API before upgrading.

Question Icon

What data do I need to find an email address?

You only need the person's name and their company domain. Note that free or public domains are blocked, so the find email by name and domain API works against professional or business domains.

Question Icon

What does the email finder API return when no match exists?

If no valid address is found, the API returns {"email":null,"status":"not_found"}. If you query a free domain, it returns a Free domains are blocked error.
