What makes a B2B buyer reply to a cold email?
The short answer
B2B buyers reply when an email is short, clearly written for their world, and asks one easy question. A first line about their market beats a line that repeats what their company does. Keep paragraphs to two sentences, use their first name only, and judge every version by booked calls instead of reply rate.
What should the first line of a cold email say?
Something true about the buyer's market, in one short line.
Most cold emails open by telling prospects what their own company does, which they already know. We have written heavy research lines and light "saw that you do X" lines, and we dropped both.
What works for us is one line about the world the buyer sells into. For a regulatory consultancy, it reads: Pharma teams have plenty of regulatory consulting firms to choose from. It is true, it is about their buyer, and it sets up the question that follows.
How long should a cold email be?
Short enough to read at a glance, with no paragraph longer than two sentences.
Buyers read cold email on their phones between other things. Long paragraphs look like work, and work gets skipped.
Our rule is two sentences per paragraph at most, with the question and the personal line each standing alone.
Should you use the prospect's company name?
Use their first name and leave the company name out.
A company name dropped into a template is the most familiar personalization trick there is, and buyers spot it at once. Pasted names also come out wrong, with legal suffixes and odd capitals that give the template away.
What should a cold email ask for?
One easy question that a buyer can answer with a word.
Asking for a meeting in the first email is a big request from a stranger. A question about whether they are in the running when their buyers go shopping is easy to answer, and a yes opens the conversation.
We also never name a call length. Calls run as long as they need to, and promising a quick one sets up a small broken promise before the first hello.
Should you judge cold email by reply rate?
No. Judge it by booked calls, because reply rate and meetings do not move together.
In our own three-way test this summer, the version with the lowest reply rate booked the most calls.
A reply rate counts every answer, including polite refusals and out-of-office notes. Booked calls count the buyers.
Does positive or negative framing get more replies?
Positive. A line that points out what a buyer lacks reads as an insult from a stranger.
It is tempting to open with a problem, like a thin pipeline or a dated website. From someone the buyer has never met, that lands as criticism.
Lines about opportunity and about the buyer's own market keep the door open.
Frequently asked questions
How many follow-ups should a cold email sequence have?
We run three emails in total, spaced four and then five days apart. Past that point, each extra email asks more of a buyer who has already seen two.
Should a cold email include links?
Keep cold emails free of links and images. Plain text reads like a personal note and is kinder to deliverability.
Can AI write a good cold email?
Only after a real rewrite. We use AI for research and first drafts, then cut every phrase that sounds generated before anything sends.
