Email enrichment: find a work email from a name and company

Email Enrichment takes a person's name and their company's website domain and returns their work email address when one is found. Use it when you know who you want to reach and where they work, but not how to email them.

What it tells you

• The work email address for that person, when one is found.
• Whether a match was made at all, so a miss is unambiguous rather than a blank field.
• The company domain the returned address belongs to.
• A suggested next action alongside the result.
• The credits used on the call and your remaining balance.

What you need to provide

• The person's first name and last name.
• The company website domain, for example acme.com.
• Instead of separate first and last names, you can send a full name that splits into at least a first and a last name (the fullName field, or its alias name).

What it costs

5 credits per lookup. This one is success-based: you are charged 0 credits when no email is found. Live per-product costs are shown on the Billing page in your dashboard.

How to run it

• In the dashboard: Email Enrichment
• From your code: POST /v1/email-enrichment, then see the Developer Hub at app.1lookup.io/developer-hub.

Good to know

• Results are point-in-time. People change jobs and companies retire addresses, so an address found today can stop working later.
• The address that comes back is at the domain you send, so send the domain of the person's current employer.
• Because a miss costs nothing, you can run a list without paying for the names that do not resolve.
• If you have a public LinkedIn profile URL rather than a name and domain, use the LinkedIn Email Finder product instead.
• Names and work emails are personal data. Use them for legitimate business purposes only.
