Marketing team work emails at the companies you sell to, under 2 cents each
44 of 50 marketing emails came back “valid”, but only 8 of those 44 could be confirmed with the company's mail server: 6 of the 7 companies accept mail for any address. 82 cents for all 50.
Name the companies you want to reach and the team. Your AI assistant finds the people on that team with their role and work email, checks every email a second time with the company's mail server, and tells you which ones it could confirm.
I sell to B2B software companies. Find up to 10 marketing people per company at linear.app, ramp.com, vanta.com, retool.com, posthog.com, clay.com, attio.com and loom.com, with work emails I can send to. Tell me which emails you could confirm and what it cost.
What you get
- Up to 10 people per company on the team you choose, with their role and work email
- Every email checked twice: when it was found, and again with the company's mail server
- A clear split: confirmed, can't be confirmed because the company accepts any address, and failed
- A private link with the list, for you only; nothing is sent to anyone
A real run
We ran this once on Oct 9, 2026 (São Paulo time) for the eight companies above, marketing team: about 2 minutes, $0.816. Names and emails stay in the private link. The companies are examples; none is involved.
44 of 50 marketing emails came back “valid”, but only 8 of those 44 could be confirmed with the company's mail server: 6 of the 7 companies accept mail for any address. 50 emails (49 named people) at 7 of 8 software companies cost $0.82, about 1.6 cents an email.
Retool's mail server answered for each address and confirmed 10 of its emails, including all 8 marked valid. At the other 6 companies the server accepts any address, so it can't say whether their 40 emails are real; nobody outside the company can.
No one on the marketing team turned up at clay.com.
What you do with it: write to the 10 emails the mail server confirmed first, then the other 34 marked valid, and watch for bounces.

How it works
Your AI assistant does these steps for you. You pay a few cents per run; nothing to install or configure.
Finds the team at each company
Up to 10 people per company on the team you choose, with their role and work email, from public professional sources.
Checks every email again
Asks each company's mail server whether the address exists, and says when the server accepts any address.
Gives you a private list
Everyone grouped by company with both checks, and the cost per person.
Questions
Where do the people come from?
Public professional sources: company websites, press and public profiles.
What does it cost?
About 82 cents for 8 companies and 50 emails, under 2 cents an email: about 5 cents per company searched plus under 1 cent per email checked. You start with $5 free.
How accurate is it?
Counts are a snapshot at the moment you run it; people change jobs, so a rerun can differ. Your AI assistant only reports what the two checks say.
What does "accepts any address" mean?
Many companies set their mail server to accept mail for any name, so asking the server cannot tell a real address from a made-up one. That does not make them wrong; nobody outside the company can confirm them. Send with care and watch for bounces.
Will the people know?
No. Nothing is sent to anyone; the checks ask the mail server without sending an email.
Can I email them?
Follow anti-spam rules where you and they are: say who you are, why you write, and how to opt out.
What if a company returns no one?
Try another team or a broader level. Smaller companies often have no public emails for a given team.
How often should I run it?
Right before each outreach push; ask your AI assistant to rerun it for the companies on your list.
