Why it works.
Your happiest, highest-retention customers share a shape: size, model, stage, the problem they walked in with. The fastest good list you'll ever build starts from them, not from a blank filter.
Senders brings the data and the sending. You bring what you know.
Senders brings
- Data from 80+ sources: Firmographics and signals on your seed accounts and on every company that resembles them.
- Signal: What your best customers share (size, sector, model, signals) and how closely each lookalike matches.
- Verification: Every address checked before anything sends.
- Sending: From your own mailbox, after you approve each note.
You bring
- Which customers actually count as best. A great logo can be a painful account.
- The real pattern behind your best work.
- The opener: the specific reason each one fits.
How it runs.
Senders does the legwork at every step. The calls stay yours.
Senders
Looks at what your seed accounts share (size, sector, model, signals) and returns lookalikes grouped by how closely they match.
Your call
“[B] is a great logo but a painful account. Drop them. The real pattern is [A, C, E].”
Senders
Re-derives the profile from the accounts that represent your best work and tightens the list.
Your call
“Open each email with the specific reason they look like a fit. Not ‘I noticed your company.’”
Senders
Leads every note with the concrete shared shape, verifies each contact, and sends from your mailbox once you approve.
Your call
“Send the closest matches first.”
What just happened.
A database can cluster companies. Only you know which customers you actually want more of. You corrected the seed, and the whole list got better.
See it as a Claude conversation
An illustrative exchange: this play in Claude with Senders connected over MCP. ChatGPT works the same way.
You
Here are five of our best customers: [A, B, C, D, E]. Find me more companies that look like them.
Claude, using Senders
Looks at what they share (size, sector, model, signals) and returns a set of lookalikes, grouped by how closely they match.
You
Actually, [B] is a great logo but a painful account. Drop them from the pattern. The real pattern is [A, C, E]: mid-market, product-led, no in-house deliverability person.
Claude, using Senders
Re-derives the profile from the three that represent your best work and tightens the list.
You
Better. Open each email with the specific reason they look like a fit. Not "I noticed your company."
Claude, using Senders
Leads every note with the concrete shared shape, not a generic hook.
You
Send the closest matches first.
Claude, using Senders
Sends the closest-match notes from your mailbox once you approve them, and holds the rest.
The first note.
Short, specific, and honest: a real reason for the email, one true ask, and an easy out. The brackets fill in from what you know and what Senders finds.
We work with a handful of [mid-market, product-led B2B] teams that, like [their company], [shared situation]. We help them [outcome]. Your setup looks strikingly similar, so it felt worth reaching out. Open to a quick look at whether it'd fit?
[Name]
Kept honest.
The note names the real, specific fit. You decide which customers define best.
