How to write a cold email people actually reply to
Updated October 17, 2026 · 6 min read · Montegra Studios
Most cold emails fail for the same reasons: they're long, they're about the sender, and they ask for too much. A good one reads like a short note from a person who did a little homework.
Start with them, not you
The first line should show you know who you're writing to. Mention something specific and true: something on their website, a role they're hiring for, a change in their business. Skip the 'I hope this finds you well' and 'My name is…' openers.
If you can't find anything specific, that's a sign the person may not be a good fit for the email at all.
Make one clear, small offer
Say what you do in one sentence, in the reader's terms. Then offer one small next step that is easy to accept: a short video, a one-page review, a 15-minute call, an answer to one question.
Asking for an hour-long demo in a first email is like proposing on a first date.
End with one question
Finish with a single, easy question: 'Would that be useful?' or 'Worth a quick look?' Multiple questions or multiple links make replying harder.
Keep it short
- Aim for 50 to 120 words in the first email.
- Use short paragraphs: one to three sentences each.
- One link at most, and only if it really helps.
- No attachments in a first email; they look risky and hurt deliverability.
Write a subject line like a colleague would
Short, plain and specific works best: 'Quick question about your menu', 'Your open designer role', 'Backups at Acme'. Avoid all caps, exclamation marks, and words like 'free!!!' or 'act now', which look like marketing and can trigger spam filters.
Personalize the parts that matter
Variables like first name and company help, but they aren't personalization on their own. The line that matters is the one about their situation. Write that line by hand for your most important prospects, and use a template for the rest.
Common mistakes
- Talking about your company's history, awards or team size before the reader knows why they should care.
- Several offers in one email.
- Fake 'Re:' or 'Fwd:' subject lines. They're misleading, and under anti-spam laws a misleading subject line can be unlawful.
- Sending from a no-reply address. Replies are the whole point.
- Forgetting your business name, mailing address and an easy way to opt out, which Canadian and US law require in commercial email.
An example
Subject: Quick note about your website
Hi Dana, I was looking at your site on my phone and the menu opens as a PDF, which is hard to read on a small screen. I run a small web studio nearby. If it's useful, I can record a short video showing two or three quick fixes. No cost, no call needed. Would that be helpful?
