Cold Email That Gets Replies, and Stays Legal

The legal part, briefly

Rules differ by country and this is not legal advice, but the common requirements are consistent enough to state.

Identify yourself honestly, including a real postal address in many jurisdictions. Do not use deceptive subject lines. Provide a working way to opt out and honour it promptly. In much of Europe and several other regions, unsolicited commercial email to individuals requires a lawful basis and business-to-business rules are narrower than people assume.

The practical version: if you would be uncomfortable explaining to the recipient how you got their address, do not send it.

The structure that works

Four short parts, in this order, and nothing else.

• One line establishing why them specifically, drawn from something real
• One or two lines on the problem you think they have, phrased as a question rather than an assertion
• One line on what you do, plainly, without adjectives
• One small ask: a question they can answer in a sentence

Personalisation that is not a merge field

Inserting a company name into a template is not personalisation and everyone can tell. The signal recipients read is whether you spent any time on them at all.

Genuine versions: something they published, a change on their site, a job they are hiring for, something they said publicly. All of these are visible in a couple of minutes and none of them can be automated convincingly.

This is why twenty a day is the right number. It is roughly what one person can do properly.

The ask is where most emails fail

Asking for a thirty minute call from a stranger is a large request, and the default answer to a large request from a stranger is silence.

Ask something small instead: whether this is even a problem for them, who handles this, whether it would be useful to see a specific thing. A reply of any kind starts a conversation; a booked meeting from cold is rare and not necessary as a first step.

Give an easy exit in the last line. Saying that you will leave it there if it is not relevant increases replies, because it removes the fear of being pursued.

Follow up twice, then stop

One follow-up after several days and one more a week later is reasonable. Beyond that you are not being persistent, you are being a problem.

Each follow-up should add something rather than repeat the ask. A relevant example, a shorter version of the point, or a genuine reason it is timely. Bumping a thread with just following up adds nothing and is the most ignored message in email.

Protect the domain you actually need

Send cold email from a separate domain, not the one your customers and invoices use.

Cold email attracts complaints even when done well, and complaints damage sending reputation. Keeping it on a separate domain means a bad month costs you a cold channel rather than your ability to reach the people who already pay you.

When cold email is the wrong tool

If your product is low priced, cold email will not pay for the human time it requires. If your buyers are hard to identify from public information, personalisation is impossible and the whole method collapses.

And if you have any warm channel at all, use it first. A referral, a past customer, or someone who already reads you will outperform any cold sequence by a margin that makes the comparison silly.
