Cold email that books real meetings.
Not a list you have to work yourself, and not an inbox full of 'thanks, not interested'. We run the whole thing and hand you calls with people who agreed to turn up.
You approve every prospect · no charge for no-shows
Email and LinkedIn, against the same list.
Running one without the other leaves replies on the table. Both are aimed at prospects you signed off, so nothing goes out to a business you didn't want approached.
10 dedicated inboxes across 5 domains, warmed before they send a single message, then capped to specialist-benchmarked daily limits — insider knowledge of what actually lands. That's 5,250 emails a month reaching 1,750 new decision-makers — deliberately paced, because volume without deliverability is just noise.
- Never sent from your primary domain
- SPF, DKIM and DMARC configured and monitored
- Three-touch sequence per person, then we stop
The same approved list, worked in parallel from your own profile. Connection requests and follow-ups paced well inside LinkedIn's limits, so the account stays safe. People check who's messaged them before answering a stranger's email — running both is what lifts the reply rate.
- Runs from your profile, not a burner
- Paced to stay inside platform limits
- Same list, so the two channels reinforce
Same prospect. Two first emails.
Drag across. On the left, what lands in a decision-maker's inbox most mornings. On the right, what ours looks like.

Oursquick question
Hi Dana,
Saw Kellbrook opened a second studio in Marylebone this year.
Thousands of businesses could buy from Kellbrook, and a handful are showing signs they're ready now. I've done some digging and can send a free TAM scan naming ten accounts, who to email at each and why now.
Want it? Just reply "yes".

Sample · illustrative figures
The meeting is one outcome. It isn't the only one.
Most agencies report replies as a vanity metric and bin the ones that didn't book. But a reply is somebody who read a cold email about your business and answered — and answering is the hard part. We keep every one of them.
The meeting
A decision-maker you approved — an MD, a CEO, a founder — who agreed a time and turned up to it. That is the only thing the minimum £100 is charged against, and the only thing we count as a result.
The database
Every reply that didn't become a meeting — the not-right-now, the send-it-over, the try-me-after-the-summer — goes into a database that belongs to you. We write a year-long, value-led campaign against it, so the people who were interested but not ready hear from you again when they are.
Whenever you leave, you leave with both: the machine, and the list of everyone who put their hand up.
You only pay when someone turns up.
Most agencies bill you a fat retainer and hope you don't count the meetings. We split it: a flat fee that keeps the machine running, then a per-call fee that only lands when a real decision-maker sits down with you.
No-shows cost you nothing
That risk sits with us, which is the point.

Deliverability, compliance and the awkward bits.
The questions worth asking any outbound agency before you hand them your brand.
Who writes the emails?
How do you protect our domain reputation?
Isn't this spam?
Is it GDPR compliant?
What about LinkedIn?
What do we keep if we leave?
Two of the calculations behind all of this are published as free Claude skills: how many new leads a day a set of mailboxes can sustain, and which rows on a UK list you are lawfully allowed to email at all. Nothing gated, and no reason to talk to us first.
Let's see if your market is big enough.
Twenty minutes. We'll size how many businesses actually match your buyer — across the UK, and internationally where it fits — and tell you if the number's too small to bother.
