Every figure on this site is a count of work we have done. Pipeline and closed revenue are our clients’ results, and results vary. Replies are shown as they arrived, with senders blurred at source.

01 The engine

Emails written on science, not taste.

We spent three years and four million emails finding out what actually gets answered. The model learned it. Now it writes with it, for one person at a time.

The corpus

Four million sends taught it.

Three years of our own mail. Not a public dataset, not scraped. What went in was every email we sent and what came back; what comes out is the four decisions the engine makes about every email it writes.

What it learned

The science of a cold email.

Every send came back as data. What got opened, what got answered, what got deleted. The model turned that into rules it writes with.

  • 01

    Subject lines

    Which openers get opened, by which persona, at which seniority.

  • 02

    Length

    How many words earn a reply before attention runs out.

  • 03

    Call to action

    Soft ask or hard ask, meeting or question, per persona.

  • 04

    Structure

    Where the personalisation sits, where the point lands.

  • 05

    Send window

    Day and hour, per mailbox, per timezone.

  • 06

    Cadence

    The gap between touches, and how much runway a variant gets.

It has never seen your market, so the angles still get tested rather than assumed. And it does not decide whether your offer is any good. Nothing does that but your offer.

Per lead

Six or more variables, then a discard list.

The engine finds far more than it uses. A detail that is true but irrelevant reads as surveillance, so it gets thrown away.

Written into the email

  • 01Second req open since the 14th
  • 02Job spec asks for outbound
  • 03One AE on the team
  • 04Site sells to ops leads
  • 05Round closed in March
  • 06Second persona, derived

Thrown away

  • ×Alma mater of the VP Sales
  • ×Podcast appearance, two years old
  • ×Office move
  • ×Investor names from the round
  • ×Personal marathon time

True, and useless. Most agencies never show you the second column.

How an email gets written

Six passes,
every time.

The same sequence runs for every single lead. It does not get skipped when the list gets big.

01Read the companyResearchSite, product, hiring, round, stack. The agent goes wide before it goes narrow.
02Keep six thingsFilterThe few facts that touch your offer. Everything true but irrelevant gets discarded.
03Pick the angleChooseWhich of your tested angles this particular company is most likely to answer.
04Write to the personDraftOne email, built from what was found. Never a template with a merge field in it.
05Apply the scienceModelSubject, length, call to action and send window come from four million sent emails, not from taste.
06A person reads itGateNothing sends until somebody has looked at it. That gate never comes out.

Try the rules yourself

The same rule-set, free, on your email.

The model’s mechanical rules run in the open: paste your cold email and see what it would keep and what it would cut.
