Cold email template: the 80-word email buyers answer (34 million emails checked)
You need a cold email template that a busy buyer can read in one breath. This one is built on a simple idea: short and plain tends to beat long and clever. Below you'll find the template, a before-and-after rewrite, and what two large vendor datasets say about length, questions and subject lines. We'll also show where the data stops, so you can test this on your own list and not just take our word for it.

Quick answer · How long should a cold email be?
Keep your cold email under 80 words. Say why you're writing to them, why now, and why you. Then end with one easy question. That's our rule of thumb, not a law. It follows the direction of the Hunter and Boomerang data: shorter, plainer emails tend to get more replies.
The cold email template (copy and paste)
Every line has one job. The trigger answers why you and why now. The problem shows you understand their world. The proof answers why me. The question makes replying easy.
``` Subject: [3-4 words about their situation]
Hi [First name],
[Line 1 – The trigger: one specific thing you noticed about them.]
[Line 2 – The problem: what usually comes with that trigger for teams like theirs.]
[Line 3 – The proof: one short line on what you did for a similar team. Real results only.]
[Line 4 – One easy question, e.g. "Worth a 10-minute look next week?"]
[Sign-off] [Your name] ```
One warning about Line 3. Never make up a result. If you don't have a real one you can stand behind yet, cut the line. That's better than inventing proof.
Before and after: same email, about 100 words cut
Here's a typical first draft. It's polite and it's long, about 160 words. It talks about the seller, not the buyer, and it ends with three questions.
Before (about 160 words)
``` Subject: Quick introduction and a few ideas for your team
Hi [First name],
I hope this email finds you well. My name is [Your name] and I work at [Your company]. We help sales and operations teams improve the way they work, save time on manual tasks, and get better results across the board. I know you are busy, so I will try to keep this short.
I came across your profile and saw that your team has been growing. We offer a wide range of features, including reporting, automation, integrations, dashboards, and dedicated support. Our platform is easy to set up, and our team is always happy to help with onboarding, training, and any questions that come up along the way.
I would love to set up a call to walk you through our platform, learn more about your goals, and see if there is a fit. Are you free on Tuesday or Thursday? Or would another day work better? Who else on your team should join?
Best, [Your name] ```
After (about 60 words)
``` Subject: Your new sales hires
Hi [First name],
I saw your team is hiring [number] new sales reps this quarter.
When teams like yours grow this fast, onboarding often slows down and new reps take longer to close their first deals.
For a similar team, we [short, real result you can prove, in plain words].
Worth a 10-minute look next week?
Best, [Your name] ```
What changed:
- The intro is gone. They can see your name already.
- The feature list is gone. One problem they probably have beats ten features they didn't ask about.
- Three questions became one. It asks about interest, not a calendar slot.
- The subject is about them, not you. And it's four words long.
What the data says
There are two datasets here. Both come from companies that sell email tools, so treat them as vendor data. They're useful, but they aren't independent research.
Hunter: 34 million cold emails (2024)
Hunter sells an email-finding and cold-outreach tool. In an article updated on 26 April 2024, it looked at 34 million cold emails sent by Hunter Sequences users between 2022 and 2024. It removed campaigns with fewer than 50 emails. It also removed campaigns with reply rates above 30% or below 0.5%, because some of the top ones went to warm audiences.
| Word count | Average reply rate |
|---|---|
| 0–19 | 3.7% |
| 20–39 | 4.5% (highest) |
| 40–59 | 3.4% |
| 60–79 | 4.0% |
| 80–99 | 4.1% |
| 100–119 | 3.7% |
| 120–139 | 3.6% |
| 140–159 | 3.5% |
| 160–179 | 4.0% |
| 180–199 | 3.7% |
| 200+ | 3.7% |
Source: Hunter, 2024 (vendor data), 34 million cold emails.
Hunter's own caveats, in plain words:
- Hunter says the advantage "isn't spectacular." Much longer emails got similar results.
- A reply counts whatever it says. "Please remove me" counts the same as "tell me more."
- Hitting a word count won't lift your reply rate by itself.
- Context matters: your list, your offer and your timing.
So the honest reading is this. In this data, the 20–39 word band did best, but the gaps between bands are small. Length looks like one lever among many, not the main one.
Boomerang: 40 million emails, mostly person-to-person (2016)
Boomerang makes an email productivity tool. In a February 2016 post by Alex Moore, it looked at more than 40 million emails that its customers had asked to be reminded about if nobody replied. A "response" meant an actual reply. Most of these were person-to-person emails, not cold emails. That's why the response rates are far higher than anything you'll see in cold outreach.
- Length: 50–125 words was the sweet spot, with response rates above 50%. Emails of 25 words got about 44%. A subject with an empty body got only 11%.
- Reading level: Emails written at a third-grade reading level got 36% more responses than college level (53% vs 39%), and 17% more than high-school level.
- Questions: Emails asking one to three questions were 50% more likely to get a response than emails with none. An email with three questions was 20% more likely to get a response than one with eight or more.
- Subject lines: Subject lines of 3–4 words got the most responses. Only 14% of emails with no subject line got a response.
Source: Boomerang, 2016 (vendor data), 40 million+ emails.
Where the two datasets agree and disagree
They agree that short and plain beats long and dense. They disagree on the exact best number. Hunter's best band for cold email was 20–39 words. Boomerang's sweet spot for mostly warm email was 50–125. Different audiences, different years, different tools. That's why we treat 80 words as a ceiling, not a target.
Four rules worth testing
- Use plain words. In Boomerang's data, simpler reading levels tended to get more responses. Write like you talk. Short sentences. No jargon.
- Ask one easy question. Boomerang found that emails with some questions beat emails with none. For a cold email, one clear, low-effort question is a good place to start. Ask about interest ("Worth a look?"), not a calendar slot.
- Keep the subject to 3–4 words. That's what got the most responses in Boomerang's data. Make it about their situation, not your product.
- Stay under 80 words. This is our rule of thumb, not a study finding. It sits between the two datasets and leaves room for the trigger, the problem, the proof and the question.
SellSip rule of thumb, not a study.
The 5-minute checklist
Run this before you hit send:
- [ ] Is the subject 3–4 words, and is it about them?
- [ ] Does Line 1 mention something specific and real about this person or team?
- [ ] Does Line 2 name one problem, not a list of features?
- [ ] Is the proof line a real result you can back up? (If not, cut it.)
- [ ] Is there exactly one question, and is it easy to say yes to?
- [ ] Is the whole email under 80 words?
- [ ] Read it out loud. Does it sound like a person talking?
- [ ] Did you delete "I hope this email finds you well"?

Questions people ask
How long should a cold email be?
In Hunter's 2024 data on 34 million cold emails, 20–39 words had the highest average reply rate. Hunter also notes the edge "isn't spectacular." Our rule of thumb is to stay under 80 words and treat that as a ceiling. Then test on your own list.
What is the best cold email template?
No template wins everywhere. A good starting cold email template has four lines: a specific trigger, the problem that tends to come with it, one real proof line, and one easy question. Use it as a base, then test changes against your own results.
How many questions should a cold email ask?
Boomerang's 2016 data, which was mostly person-to-person email, found that one to three questions beat zero. For cold email, we suggest starting with one easy, interest-based question. It's easier to answer, and it keeps the email short.
How long should a cold email subject line be?
In Boomerang's data, subject lines of 3–4 words got the most responses, and emails with no subject line did poorly. That data is mostly warm email, so it's worth testing on your cold lists too.
