# How long should a cold email be? The word budget, line by line
> A cold email should be 50 to 125 words in the body, and under 100 words on a first touch. That is four to six sentences: one fact about the reader, one problem, one proof and one ask, short enough to read on a phone without scrolling. Follow-ups get shorter, 30 to 60 words, and the subject line stays at two to six words. The words that push a draft over budget are usually the ones that compensate for a missing fact about the reader, so the fastest way to shorten a cold email is to find that fact first.

## How long should a cold email be? The short answer
**A cold email should be 50 to 125 words in the body, and under 100 words on a first touch.** That is four to six sentences, one idea and one ask, short enough to read on a phone without scrolling. Follow-ups get shorter, not longer: 30 to 60 words. A subject line of two to six words sits on top of all of it.
Those numbers are a range, not a law, and the rest of this guide explains where they come from, when to break them, and how to cut a draft down to size without losing the one line that earns the reply. If you want to check a draft right now, paste it into the length checker in section 3. It counts words, sentences and reading time in your browser and sends nothing anywhere.
| Email | Body length | Sentences | What it must contain |
| --- | --- | --- | --- |
| First cold email | 50 to 100 words | 4 to 6 | One fact about them, one problem, one proof, one ask |
| First email to a C-level | 40 to 75 words | 3 to 4 | The fact and the ask, proof in one clause |
| Technical buyer (engineering, data) | 100 to 150 words | 5 to 8 | The specific detail they would ask for on a call |
| Follow-up 1 and 2 | 30 to 60 words | 2 to 3 | One new element, the same ask |
| Break-up email | 20 to 40 words | 2 | A closed question they can answer in one word |
## Why cold email length matters: three mechanics
Three mechanics push a cold email toward 100 words: the size of a phone screen, the time a stranger will spend reading, and the weight of the message for spam filters. "Keep it short" is not a matter of taste, and knowing the three tells you when the rule bends.
### 1. The phone screen
A large share of business email is first opened on a phone, and a cold email is read in the few seconds between two other things. On a typical phone, the body area under the sender line and subject shows about ten short lines before the reader has to scroll. A 90-word email fits in that window. A 250-word email does not, which means the ask, sitting at the bottom, is never seen by the people who decide in the first screen whether to keep reading.
### 2. Reading time
Adults read English prose silently at around 238 words per minute on average, according to a 2019 meta-analysis of 190 reading studies by Marc Brysbaert. At that speed, 100 words take about 25 seconds and 250 words take over a minute. Twenty-five seconds is a favor a stranger can grant you. A minute is a meeting you did not book.
### 3. Weight and deliverability
Length also has a technical side. Every extra link, image and block of HTML gives a spam filter more to evaluate. Gmail also clips any message whose HTML code goes above 102 KB behind a "View entire message" link: a designed template with inline styles and tracking code gets far closer to that limit than a plain text note, which weighs a few kilobytes. Short and plain is the version that reaches the inbox and renders the same everywhere.
On the reply side, the most cited public number comes from an analysis of over 40 million emails by the email productivity company Boomerang: messages of 50 to 125 words had the highest response rates, around 50 percent, on email of every kind rather than cold outreach specifically, so it is not a cold email reply rate. Read it for its shape, not its level. What transfers is the shape of the curve: response drops as the body grows past about 125 words.
## Cold email length checker: paste your draft
**Paste the body of your email below, pick the type of message, and the checker returns the word count, the number of sentences, the longest sentence, the reading time and a verdict against the budget for that type.** Leave out the subject line and the signature block, they are counted separately. Nothing leaves your browser.

### Is this cold email the right length?
The budget changes with the message. Pick what you are sending, then paste the body.

Word counts are a proxy. A 70-word email with no fact about the reader is still too long, because every word is filler.
## How long should a cold email be, line by line
A total word count is hard to write to. A budget per line is easy. A first cold email that works has four parts, and each one has a job and a size.
| Line | Job | Budget | Example |
| --- | --- | --- | --- |
| Opener | Prove you picked them on purpose | 10 to 25 words | "Saw that Northwind opened three SDR roles in Austin this month." |
| Problem | Name the consequence of that fact | 20 to 35 words | "New reps usually spend their first weeks building lists by hand, and a good part of the numbers they find go to a switchboard." |
| Proof | One reason to believe you | 15 to 25 words | "We cut that to one afternoon for a 12-person team at a logistics company last quarter." |
| Ask | One question, answerable in a line | 5 to 15 words | "Worth a 15-minute look before they start?" |
Add the four maximums and you land at 100 words. Add the minimums and you land at 50. That is the whole range, and it explains why the "50 to 125 words" advice keeps coming back: it is roughly what four useful sentences weigh.
The opener is the part most drafts get wrong. "I hope this email finds you well" is seven words that do nothing. "I came across your profile and was impressed by your background" is eleven. Both exist because the writer had nothing specific to say, and they push the email over budget before it has started. The first line of a [cold email template](https://derrick-app.com/cold-email/cold-email-template) that gets replies is always a fact about the reader's company, not a greeting.
## How long should a cold email be for a CEO, a technical buyer or a warm lead?
The budget moves with who reads it and why. Three adjustments cover most cases.
**Senior executives: shorter.** A CEO or a VP triages dozens of unsolicited messages a day. Three sentences, 40 to 75 words, with the proof folded into the problem line. If the fact you open with is strong enough, the email barely needs anything else.
**Technical buyers: slightly longer.** An engineering lead or a data team manager wants the detail they would otherwise ask for on a call: which system, which format, which limit. Going to 120 or 150 words is fine if the extra words are specifications, not adjectives. The test is simple: would they need this sentence to decide whether to reply? If yes, it stays.
**After an event or a warm intro: longer is allowed.** Once someone has met you, the email is no longer fully cold. You can recap the conversation in a few lines and still get a reply. The budget of a cold email applies to strangers.
Country changes the courtesy lines, not the budget. English-speaking inboxes tolerate very short notes. In France, Germany or Italy, a message that drops the greeting and the closing formula can read as abrupt, so keep the courtesy lines even when you cut everything else. The [email sign offs guide](https://derrick-app.com/cold-email/email-sign-offs) covers which closing to use by country.
## When a long cold email is really a data problem
Put a 250-word cold email next to an 80-word one and look at what the extra words do. In most drafts they explain who the sender is, list the product's features, and hedge with phrases like "not sure if this is relevant, but". None of that is there because the reader needs it. It is there because the writer did not know one thing about the reader that would have made the email obviously relevant.
That is the useful way to think about cold email length. **The words you can cut are the words that compensate for a missing fact.** When you know that the company just opened three sales roles, uses a particular CRM, or raised a round last month, the opener writes itself in 20 words and the rest of the email has something to hang on. When you do not, you write paragraphs around the gap.
So before trimming a draft, fill the gap. Derrick does it from the list you already have, on three surfaces depending on how you work:
- **In Google Sheets**, from the sidebar: Company Hiring Signal shows which accounts are hiring on LinkedIn and for which roles, and Enrich Companies fills in industry, size and location from the company's LinkedIn page. Both cost 1 credit per company and both are included in the free plan, which gives you 100 credits per month. Running the two on the same company costs 2 credits, so the free plan covers 50 accounts with both facts, or 100 with one.
- **From an AI assistant** through the MCP server, in Claude, ChatGPT or any MCP client: ask which of these accounts are hiring SDRs, and write the opener from the answer.
- **Through the REST API**, to add the fact to every new account in your CRM before a rep writes to it. The API and the MCP server are available from the Standard plan, at 20 euros a month.
Website Technologies adds another kind of opener, the tools a company runs on its site, at 2 credits per website on the paid plans. One real fact is enough. The email that opens with it is shorter because it no longer needs to argue for its own existence.
## How to cut a cold email to length: before and after
Here is a typical first draft, 136 words:
> Hi Sarah, I hope this email finds you well. My name is Tom and I am the head of partnerships at Acme, a platform that helps sales teams save time on prospecting. We work with companies of all sizes across many industries, and our customers love how easy it is to get started. I noticed that you are the VP of Sales at Northwind, and I thought you might be interested in learning more about how we could help your team. We offer a wide range of features including list building, contact data, and integrations with all the major CRMs. Many of our clients see results within the first month. Would you be open to a 30-minute call next week to discuss your current prospecting process and see if there is a fit? Best regards, Tom
Four cuts get it to budget:
1. **Delete the greeting filler and the self-introduction.** Your name is in the signature and the sender line. That removes about 30 words.
2. **Replace "I noticed you are the VP of Sales" with a fact about the company.** Her title is not news to her. Northwind hiring three SDRs is a reason to write.
3. **Swap the feature list for one proof.** A single result for a comparable team beats five capabilities.
4. **Shrink the ask.** "A 30-minute call next week to discuss your process" asks for a commitment of unknown value. "Worth a 15-minute look?" asks for a yes.
After, 63 words:
> Hi Sarah, saw that Northwind opened three SDR roles in Austin this month. New reps usually spend their first weeks building lists by hand, and a good part of the numbers they find go to a switchboard. We cut that to one afternoon for a 12-person team at a logistics company last quarter. Worth a 15-minute look before your new reps start? Tom
Same sender, same product, half the length, and the second version is the only one of the two that says anything about Northwind.
## Subject line and preview text length
The body is not the only thing with a length. The subject line should be two to six words, short enough not to be cut on a phone, where the inbox shows around 30 to 40 characters of it. Lowercase and plain works: "northwind sdr hiring" looks like a note from a colleague, "Unlock 3x More Pipeline For Northwind!" looks like a campaign.
The preview text is the first 40 to 90 characters of your body, shown under the subject in most inboxes. That is another argument for opening with the fact: the preview then says "Saw that Northwind opened three SDR roles" instead of "I hope this email finds you well". There is a full list of formats in the [cold email subject lines guide](https://derrick-app.com/cold-email/cold-email-subject-lines).
## Follow-up email length across a sequence
Most guides stop at the first email. The follow-ups are where length discipline usually breaks, because the sender feels they need to justify writing again.
The rule is the reverse: **each follow-up is shorter than the email before it, and adds exactly one new element.** A new fact, a new proof, or a new format for the same ask. It never repeats the whole pitch.
- **Follow-up 1 (day 3 or 4):** 30 to 60 words. One new element and the same ask. "One more detail: the team we worked with had the same Austin ramp-up. Still worth a look?"
- **Follow-up 2 (day 7 to 10):** 30 to 50 words. Change the angle, for instance offer something they can read instead of a call.
- **Break-up (day 14 or later):** 20 to 40 words. A closed question: "Should I close the file on this, or is it a timing thing?"
Send each follow-up in the same thread, so the earlier emails sit underneath and the new one can stay short. Timing matters as much as length here, and the [best time to send cold emails](https://derrick-app.com/cold-email/best-time-to-send-cold-emails) depends above all on knowing the reader's time zone.
## Cold email length checklist before you send
- Body between 50 and 100 words on a first touch, 30 to 60 on a follow-up.
- Four to six sentences, none over 25 words.
- The first line is a fact about their company, not a greeting.
- One ask, with a question mark, answerable in a line.
- Zero or one link, plain text, no images.
- Subject line of two to six words.
- The whole email fits on a phone screen without scrolling.
- The address has been checked. A perfect 80-word email to a mailbox that does not exist is a bounce, and bounces damage the domain that sends the next one. The [deliverability checklist](https://derrick-app.com/cold-email/deliverability-checklist) covers the rest.
Email Verification checks that an address exists before you send, at 1 credit per email, and Email Finder finds the address at 5 credits per email found. Both sit on the paid plans, from 9 euros a month, and both are billed only when a result comes back. Importing and enriching accounts, including the hiring signal above, runs on the free plan.

## FAQ
### How many words should a cold email be?
Between 50 and 125 words in the body, and under 100 words for a first touch. That is four to six sentences. Senior executives get the short end of the range, 40 to 75 words, and technical buyers can take up to 150 words when the extra words are specifications.
### How many sentences should a cold email have?
Four to six. One sentence with a fact about the reader's company, one or two naming the problem that fact creates, one sentence of proof, and one question as the ask. Keep every sentence under 25 words.
### How long should a follow-up email be?
Shorter than the email before it: 30 to 60 words for the first two follow-ups and 20 to 40 words for a break-up email. Each follow-up adds exactly one new element and keeps the same ask, sent in the same thread.
### Is a 200-word cold email too long?
For a first email to a stranger, usually yes. It no longer fits on a phone screen, it takes almost a minute to read, and the ask sits below the fold. A 200-word email can work after a meeting or for a technical buyer who needs specifics, but most 200-word drafts are padded with self-introduction and feature lists.
### How long should a cold email subject line be?
Two to six words. Phones show roughly 30 to 40 characters of a subject line, so anything longer gets cut. Plain and lowercase reads like a note from a person, which is what a cold email should look like.
### Should a cold email include links or images?
Zero or one link, and no images, on a first email. Each link and image adds weight and gives spam filters more to evaluate, and a plain text email renders the same in every inbox.
### How do I make my cold email shorter?
Cut the greeting filler and the self-introduction, replace your reason for writing with one fact about their company, swap the feature list for a single proof, and shrink the ask to a question they can answer in a line. Those four cuts usually halve a first draft.
