The problem

A signup or contact form often gives you nothing but an email. Routing, scoring, and personalizing that lead means knowing who's behind it — without making them fill out a longer form.

What you get

An enriched contact record you can score and route the moment a lead comes in, with no extra fields for the user to complete.

The workflow

How the calls chain together

Every response below is a live sample from the actual API — nothing mocked.

Email ValidatorGET /v1/emailvalidator5 cr

Validate & split the email

Confirm it's real and separate the domain — the key to everything downstream.

isValidtruedomainmyspace.comisCompanyEmailtrue

Sample response

{
  "creationDate": null,
  "domain": "myspace.com",
  "email": "[email protected]",
  "username": "support",

  "isValid": true,
  "isMxValid": true,

  "smtp": {
    "valid": true,
    "reason": "Connected"
  },

  "checksum": 797
}

↓ passes the company domain to the next step

Recipe questions.

What to know before you wire it up.

Talk to the team →

What if the lead uses a free email like Gmail?

You'll still get validation, deliverability, and any public Gravatar profile. Domain and company enrichment naturally apply to business domains — the email validator's isCompanyEmail flag tells you which path to take.

Does this work in real time during signup?

Yes. Every step is a fast request, so you can enrich inline and route or score the lead before the welcome screen loads.

Will company data always be available?

Company lookup covers SEC-registered public companies. Private companies won't match, so treat that step as an optional enhancement rather than a guarantee.
