The cold email that gets a reply is under 75 words

By Travis Heurtelou · 6 min read · September 14, 2026

The short version

One email does three things: says why you're writing to this person, says one thing about their situation they'd want to hear, and asks one question.
The offer sets the reply rate. Across ListKit's published set of 200 scripts the spread was 0.012% to 6.62% on similar prose. Rewording a thin offer moves nothing.
'Are you tired of X?' is the most-written opener in that set and one of the worst.
Two emails: the offer, then one follow-up with one new thing. Not eight.

The three sentences that do the work

A cold email has one job: a reply. So it needs three things. Why you're writing to this person and not the next one on the list. One thing you know about their situation that they'd want to hear. One question they can answer in a line.

We cap the body at 75 words. Over that, the reader is scanning for the ask and skipping the rest. Under 30 there's usually no reason to reply. Most of ours land between 40 and 60.

One question. Two asks in one email and the reader answers neither.

Subject: quick one

Hey [[FirstName]], you're hiring a second estimator at [[Company]], which usually means the bid volume is there and the pipeline to feed it isn't.

We put walkthrough requests from property managers in [[ServiceArea]] on your calendar, in your company's name, and hand you the thread.

Want two next month to see if they're the right buildings?

Fifty-three words. The hire is the reason it's them. The line about bid volume is the thing they'd want to hear, because it's true of most shops adding an estimator and it says we know the trade. The question is one they can answer with a yes, a no, or a number.

The offer sets the number

ListKit published 200 of their best-performing scripts in 2026 with the numbers behind each: 9.5 million emails, 3.7 million prospects, 5,747 positive replies. The worst script in the set got 0.012% of prospects to reply positively. The best got 6.62%. That's a 550× range, and the prose is broadly the same across all 200: short, plain, one ask.

So when a campaign is flat, the fix is almost never a rewrite. It's the offer, or the list. A framework removes words from between the reader and the offer. It can't put an offer there.

Before writing a word we check whether we can name the sentence that says why this person, and the sentence that says why now. Why-now comes from a signal about them: a hire, a rating, a posting, a move. If there isn't one, the problem is the list, and no opener fixes it.

The opener everyone writes is near the bottom

In the same 200 scripts, 63 open with some version of 'Are you tired of X?' or 'Struggling with Y?'. That's a third of the set. Their median was 0.145% per prospect, second from the bottom of eleven angles.

The top angles didn't pitch. One implied the sender already knew the reader, the other invited them to something instead of selling them something. Both ran 7 to 11 times the pain-probe median. The catch on the first: the strongest example was a content-free 'Hey, how are you?' that works by faking familiarity. Don't. Faking prior contact ('we got your application', 'just tried calling') sat mid-table anyway, so the deception buys nothing.

'Free audit' openers were weak too. The free-sample band medianed 0.168%, and the free-video-audit script came in at 0.094%. A free thing the prospect has to do homework for isn't free to them.

Two emails, not eight

147 of the 200 scripts ran 7 or 8 steps. That bucket had the worst median in the set, 0.145% per prospect. Sequences of 1 to 3 steps medianed 0.380%, about 2.6× better, with fewer touches per prospect.

Part of that is confounding: short sequences cluster on offers that don't need nurturing. The honest read is that a long sequence doesn't rescue a weak angle. It bills more sends for it.

We send two. The first carries the offer. The follow-up says one new thing: a different piece of proof, a narrower version of the offer, a different question. 'Bumping this' isn't a new thing, and the reader knows it.

Subject lines

Lowercase, two to four words, no merge field. Something you'd write to a coworker. The subject's job is to not look like a campaign. The email's job is everything else.

Under 75 words. One reason it's them. One thing they didn't know. One question. Two emails. Then measure positive replies per contact, and if the number's low, look at the offer and the list before the words.

Questions

Should I personalize the first line?

Only with something that changes what you'd say next. A signal about their business: a hire, a rating, a posting. A compliment about their LinkedIn post is a merge field with extra steps, and readers spot it.

Where does the proof go?

One line, usually in the second email, as a specific: what happened for a named kind of buyer. If it's on your website but not in the email, it doesn't exist to the reader.

How few words is too few?

Under 30, there's usually no reason to reply. You've said hi and asked, without the middle sentence that makes answering worth their time.
