Look up anyone’s verified email
An email lookup API finds someone’s email address for you. Send a name and company domain, or a LinkedIn URL, and MoltSets returns a verified address with an A–F risk score and the matched LinkedIn profile — in one API or MCP call, charged only when an email is found.

Find an email from whatever you have
Start from a name and company or a LinkedIn URL. Each lookup is its own endpoint, so you call exactly the one you need and pay only when an email comes back.

}How you know what to trust
No headline match-rate claim — every record tells you how recently it was confirmed instead.
01 / Every email graded
A is validated deliverable, B is known engagement, C is a catch-all server, D is known bad and F is no signal. Suppress D at the list level.
02 / Dated evidence
Every email comes with the date of the latest evidence that it works: a validation, an open, a click or an order. A bounce never counts.
03 / Matched to a real profile
Name searches resolve to a LinkedIn profile first, so the email belongs to the person you asked for, not a pattern guess.
04 / Profiles kept current
Job changes are reprocessed on a rolling basis, so a lookup returns the address at someone’s current employer.

Questions & answers about the email lookup API
Frequently asked questions about finding email addresses.
An email lookup API finds someone’s email address for you: send a name and company, or a LinkedIn profile, and get back a verified address. MoltSets returns it with an A–F risk score, over REST or as a tool for AI agents over the MCP.
A full name (or first and last name) and the company’s domain, such as acme.com, or the person’s LinkedIn URL. Full company URLs are normalised to the domain automatically.
Yes, that’s reverse email lookup: send the address and get back the person, their title, company and LinkedIn profile.
It’s a send-safety grade. A is validated deliverable, B is known engagement with no bounce, C is a catch-all server where deliverability can’t be known, D is a hard invalid, bounce or trap, and F is no signal either way. See email risk scores.
You’re only charged when an email is found. A miss returns status: "not_found" and costs no tokens, though it still counts as one request. Name lookups count against your search records; LinkedIn lookups against your enrichment records.
Yes. The LinkedIn-to-email endpoints take up to 100 URLs per call in linkedin_urls. Name lookups run one person per call, so run them in parallel or let an agent loop over a list.
Yes, for US records, on every plan. On the $397 and $997 plans, personal email lookups are capped at 75,000 results per week.
Yes. The Free plan includes 1,000 API calls, so you can look up emails for your own prospects before committing. Misses cost nothing.
MoltSets processes business contact data under legitimate interest and honours opt-out requests across the whole database. See the compliance page for our certifications, sub-processors and DPA.
