Give it a try
Enter a name and company — get a verified address.
One click on any LinkedIn profile
Mailfinder adds a “Find email” button to every profile you open. Click it, and it works out that person’s work address, checks it’s deliverable, and copies it to your clipboard — without ever leaving the page.
- No copy-pasting names into another tab
- Verified before it’s shown, with a confidence score
- Saved straight to your Mailsumo dashboard
Reach the right person, not their spam folder
You found the person. Get the address.
A “Find email” button sits on every LinkedIn profile you open. One click works out the address, checks it will land, and copies it for you.
Every address is checked for deliverability first, so you land in the inbox instead of a bounce. The ones we can’t confirm are labelled, never guessed.
A credit is spent only when we hand you an address, so chasing down a new lead never costs you a thing.
Stop guessing at addresses
No more firing off mail to first.last@ and hoping. You get the address, and whether it lands.
Prospect without leaving the profile
You already found the right person on LinkedIn. Getting their email shouldn’t mean a second tool.
Protect your sender reputation
Bounces are what get a domain flagged. Verified-before-you-send keeps your list clean.
Map a company in one search
A single domain search returns the addresses across a company, not just the one you asked for.
One account for the whole toolkit
Finder results sit next to everything Email Extractor collects, in the same dashboard.

Everything you need to reach someone
Find anyone on LinkedIn
A “Find email” button on any profile. One click, and the address is on your clipboard.
Search a whole company
Enter a domain and get back every address we can find at that company.
Name plus company
Give us a person and where they work, and we work out the address they use.
Verified before you see it
Every result is checked for deliverability, and that check never costs you extra.
A confidence score on every row
Know how sure we are. An address we can’t stand behind is labelled, never hidden.
Saved to your Mailsumo account
Results land in your dashboard, searchable and exportable to CSV or XLSX.
An address you can actually send to
Verified, not guessed
Anyone can generate [email protected]. We check the address actually accepts mail before we show it to you, and label the ones we can’t confirm rather than quietly passing them off as certain.
Empty searches are free
A credit is spent only when we find you an address. If a search comes back with nothing, it costs you nothing — so it never costs you to check.
Verification is included
Checking a finder result doesn’t draw on a separate verification balance. The address you get has already been checked, at no extra cost.

Questions, answered
How does Mailfinder work?
Give it a company domain, a name and a company, or a LinkedIn profile. It works out the address that person uses, checks the address is deliverable, and gives it to you with a confidence score.
What is a credit?
One credit is one address found. A credit is spent only when we actually find something: searches that come back empty are free. Credits reset at the start of each billing period and don’t roll over.
Do I need an account?
Yes. Lookups run against your Mailsumo account so your credits and results follow you between devices. Signing up is free and comes with 25 lookups a month so you can try it before paying.
How accurate is it?
Every address is checked for deliverability before you see it, and each result carries a confidence score. A few domains accept mail for any address, so the individual mailbox can’t be confirmed there — those still show as deliverable, with a small note so you know a bounce is a touch more likely.
Does verification cost extra?
No. Verifying a finder result is included. Email Verifier is a separate product for checking lists you already have, but you don’t need it to trust what Finder returns.
Does it work outside LinkedIn?
Yes. The LinkedIn button is the fastest route, but the popup searches by company domain or by name and company, so you can use it from anywhere.
Where do my results go?
Into your Mailsumo dashboard, alongside everything Email Extractor collects. You can search and filter there, and export to CSV or XLSX whenever you like.
How do I upgrade, downgrade, or cancel?
Premium is self-serve. Open Billing in your Mailsumo dashboard to change or cancel your plan; everything is handled securely through Stripe’s customer portal.
