01What it is and who is there
Cold email means emailing people who do not know you yet, usually named buyers at companies that fit your product. It works best when the list is small, well researched and tied to a trigger, such as a recent hire or funding round. Practitioners on X say what usually fails is the ask: a 30-minute call from a stranger in the first message. Anti-spam laws apply, such as the CAN-SPAM Act in the US.
02Cost and what you actually pay for
Sending by hand from your own inbox is free. Sending tools, data providers and domain setup cost money; check current pricing. The main cost is research and writing time.
03Is it right for you?
It fits B2B products and services with clear buyers you can name. It fits poorly for consumer products, and for anyone without a defined buyer. If you cannot explain in one sentence why a specific person should care, fix that first.
04Before you start
- Read the FTC's CAN-SPAM compliance guide, and the rules in your buyers' countries, which can be stricter (for example in the EU).
- Use a separate sending domain, with authentication set up, to protect your main domain.
- Build a small list of people who match a clear trigger.
- Write one short message per segment.
05Step-by-step: how to distribute here
- Define one buyer, one problem and one trigger.
- Build a list of 25 to 100 people who match.
- Write a short email: why them, why now, one specific idea, a low-commitment ask.
- Send in small batches and personalize the first line with something real.
- Follow up once or twice, briefly.
- Reply to every response, including "no".
- Track replies by segment and rewrite what is not working.
06What to post or submit
First email:
Subject: [specific, short, about them]
Hi [first name], I saw [trigger: new role / funding / post]. Teams in that spot often [problem].
We built [product] to [result], e.g. [short proof].
Worth a short reply if it's relevant? Happy to send a 2-minute video instead of a call.
[Your name]
[Physical address and opt-out line, as the law requires]07Common mistakes and do-nots
- Do not buy lists of scraped emails.
- Do not hide who you are or use misleading subject lines; CAN-SPAM forbids it.
- Do not omit a way to opt out, and honor opt-outs promptly.
- Do not send thousands of identical emails.
08How to measure it
- Track reply rate and positive reply rate by segment.
- Track meetings or sign-ups per 100 emails.
- A realistic test: 100 well-targeted emails before judging.
09Time budget
- Before: 5 to 10 hours for domain, list and copy.
- Ongoing: 3 to 6 hours a week.
10Pair it with
- LinkedIn outreach — a second touch on the same buyers.
- Case studies and customer stories — proof to reference.
- Founder-led demos and calls — what replies lead to.
- Warm intros from your network — warmer than cold.
