Finding a Prospect's Email From a Name and Company: Finder or Guess-and-Verify?

To find someone's email from a name and a company, build the address patterns that company could use, test each one against the company's mail server, and keep the one the server confirms. You can do that by hand with a verifier or let a finder do it. Both give you a confirmed mailbox or nothing, which is the point.

How the guess works

Most companies use one pattern for everyone. The common ones:

Pattern	Example for Sam Jones at acme.example
first.last@	sam.jones@acme.example
first@	sam@acme.example
flast@	sjones@acme.example
firstlast@	samjones@acme.example
first_last@	sam_jones@acme.example

Which one a company uses is set by the company, not by region or industry. Email address patterns goes through them.

The by-hand way

1. Write four or five candidates for the person.
2. Check each in the free single-address verifier.
3. Keep the one that comes back valid.
4. If every candidate is risky with "accepts all addresses", the domain is catch-all and you cannot confirm anything; see what is a catch-all domain.

For a list of guessed addresses, verify guessed addresses in first.last patterns shows how to check them in bulk.

The finder way

The SimpleVerifier email finder takes a name and a company domain, generates the candidates, runs the same mailbox check on each and returns what the server confirms. If the domain is catch-all, it says so rather than returning the likeliest pattern as a result. The finder is part of Pro at $39 a month. Starter has none.

Which to use

Situation	Use
A handful of prospects	By hand with the free verifier
A regular flow of name and company pairs	The finder
You already have addresses	Verify them; skip the finding step

What neither does

• Confirm the person reads that mailbox. A confirmed mailbox is a real mailbox, not a promise of attention.
• Beat catch-all domains. No tool can confirm a single mailbox there. Treat results as risky and send small batches.
• Replace permission. Finding is a lookup; GDPR for B2B cold email covers the sending rules.

If you use another finder, check what it does on catch-all domains and whether it verifies its results; best email finder tools compares them.

Next step

Run 100 free checks on addresses you have found or guessed. See pricing: packs start at $15 for 10,000 checks, Starter is $9 a month for 2,500 emails, and Pro at $39 a month includes the finder.
