How do I find someone's email address?
Open Prospecting > Email finder in the sidebar (/email-finder). Enter a company website,
domain or LinkedIn URL, or a person's name plus their company, and press Find email.
Warmerly searches for the best address it can find, checks it, and shows the address with a
status and a confidence score. A lookup only counts against your monthly email lookup
allowance when an address is actually found.
For the developer version, see the Email Finder API.
Look up one address
- Open Email finder and stay on the Single lookup tab.
- Choose how to search:
- By domain: type a website, domain or LinkedIn URL, for example
acme.comorlinkedin.com/company/acme. - By person: enter First name, Last name and Company or domain. At least a first or last name is required.
- By domain: type a website, domain or LinkedIn URL, for example
- Press Find email. A progress bar shows the stages: Queued, Finding company, Searching for email, Checking email, Done.
- The result shows the address, a status badge, a confidence percentage, and how it was found ("via site scrape", "pattern guess", "provider" or "mx only").
If the answer takes more than about two minutes, Warmerly tells you it is still running in the background. It will appear under Recent lookups when it finishes. A lookup that was seen before can come back instantly.
If nothing is found you will see "No email could be found", with a shortcut to try the other search mode. A domain search looks for the company's published addresses; a person search also tries likely address patterns for that individual.
What the result means
Status says whether Warmerly could confirm the address works:
| Status | Meaning |
|---|---|
| Verified | Strong evidence the address is real and accepts mail. |
| Probable | Likely correct but not fully confirmed. Safe to try, with a slightly higher chance of a bounce. |
| Unverified | Found, but Warmerly has not been able to check whether it works. |
| Invalid | The address bounced or does not exist. |
| Not found | No address could be found. |
Confidence is a score from 0 to 100. Green (80 and above) is the safest to send to, amber (50 to 79) is a reasonable guess. The score depends on how the address was found and whether it could be confirmed:
- An address read from the company's own website scores highest, because it was published by them.
- An address from a data provider ranks next.
- A pattern guess (for example first.last at the domain) starts lower and needs confirmation to reach a high score.
- On domains that accept mail for any address (catch-all), guessed addresses are capped at a middling score, because a mail server that says yes to everything proves nothing.
For a stronger answer on an uncertain address, run it through Email verification.
Look up a list
- Switch to the Bulk upload tab.
- Paste one domain or LinkedIn company URL per line, or press Upload CSV / TXT.
- Warmerly shows how many will be queued and how many lines were skipped (lines with no domain in them). Press Queue N lookups.
- You are taken to the batch page, which shows progress and results as they arrive.
Bulk lookups are domain based: one company per line. To look up a named person, use the single lookup. Large lists are sent in groups of 1,000, and each group becomes its own batch. Every batch is saved and shows up in the Data library.
Work with the results
Everything you look up appears under Recent lookups (25 at a time, Load more for the rest).
- Copy an address with the copy button.
- Re-run (the circular arrow) looks the company up again. If it finds an address it uses an email lookup again.
- Delete (the bin) removes the entry after a confirmation. It cannot be undone.
- Batch opens the batch a bulk lookup belongs to.
- Export downloads all your lookups as CSV or Excel.
- Add to campaign adds the found addresses as leads in a campaign. By default only Verified addresses are included; untick the box to include the caution-level ones (Probable, Unverified) too. Invalid and not-found rows are never added, and duplicates already in the campaign are skipped.
What it costs
Each lookup that finds an address uses one email lookup from your monthly allowance, which resets on the 1st. Lookups that find nothing, and lookups that fail, are not charged. A lookup answered instantly because the same company was recently searched still counts if it returns an address.
Before a bulk list starts, Warmerly checks you have enough allowance left for the whole batch, counting any lookups from earlier batches that are still queued. If you do not, the batch is refused and nothing is queued. The allowance is shown as a chip on the page and in Settings > Usage & limits, where you can also buy more with credits. See Lead credits, lookups and allowances and Plans & limits for the size of the allowance on your plan.
What it cannot do
- It cannot promise an address is right. It reports a status and a confidence so you can decide. Anything that is not Verified may bounce.
- It finds addresses at a company. It does not read anyone's private inbox or contact details.
- Some websites block automated reading, or only show their content after JavaScript runs. Those are harder, and an address found from a pattern will have a lower score.
- A LinkedIn person URL is best-effort: if you have a LinkedIn account connected, Warmerly can read the person's name and company for a better guess. Without one it falls back to a weaker method.
Common problems
- "No email could be found." Try the other search mode, or check the domain is spelled correctly and is the company's own website rather than a social page.
- The lookup is stuck on a stage. Leave the page. It keeps running and lands in Recent lookups.
- A message saying your email lookups are used up. Your monthly allowance is spent. Buy more with credits in Settings > Usage & limits, upgrade, or wait for the 1st.
- Bulk upload skipped lines. A line needs a dot to count as a domain. The page shows a sample of the lines it skipped.
