Cold Email

The first wall a company with something to sell runs into isn't a lack of people to build it, it's having no way to reach anyone. The only phone number listed is a switchboard, collecting business cards at events takes months, and advertising costs money while you wait for someone to search for you.

Email was the one channel in that gap that cost almost nothing. With an address you can reach a hundred people this afternoon, and they read it whenever suits them. It also doesn't interrupt what they were doing, the way a phone call does.

The problem is that everyone had the same idea. Dozens of these piled up in the inbox each day, and opening them revealed the same sentences with a different company name dropped in. The share that got deleted unread kept rising, recipients learned to recognize the shape of one within a second, and mail providers started filtering them out before anyone saw them at all.

Cold email today is the form that evolved to get past that filter. Prospecting splits into deciding who to go after and deciding how to reach them, and cold email sits on the second side. Next to it are the cold call, a first phone call with no prior contact; the sales cadence, a pre-planned sequence of which channel to use on which day; and account-based marketing (ABM), where a few named companies get treatment built specifically for them.

Sending one email starts with finding an address and ends with sorting the replies. The sequence has five steps.

1. The list. Write down the ideal customer profile (ICP) first — the conditions under which your product fits best — and pick companies against it. Make it countable: 50 to 200 people, remote-first, already running two or more collaboration tools. Then find the job titles inside those companies that actually live with the problem.
2. Sending setup. Push hundreds of messages a day through your main company address and the whole domain can get classified as spam. So teams buy a separate sending domain and warm it up over two or three weeks, adding ten messages a day. Deliverability, the share of sent mail that lands in the inbox rather than the spam folder, gets decided here.
3. Subject and first two lines. The inbox list shows only the subject and one line of preview. Keep the subject under six words, and open with why you wrote to this company rather than with a greeting.
4. The body. Five lines at most. One line on the problem they probably have, one on how you shrink it, one result from a comparable company. Close with a question that's easy to answer. "How are you handling this today?" pulls more replies than "do you have 15 minutes?"
5. Follow-ups. Most replies arrive somewhere between the second and fourth message, not the first. Send three more short ones at roughly 3, 7 and 12 days, each adding a new line. Resending the same message only reads as nagging.

Afterward, sort replies into interested, not now, wrong person, and no. Each bucket points at a different step. A pile of wrong-person replies means step 1 picked the wrong job titles, while a pile of nothing at all points back at the subject line or the sending domain.

The sender is usually an SDR, a sales development representative whose job is finding prospects and turning them into meetings, separate from the rep who closes. Once a reply turns into a discovery call — the first real conversation about the customer's situation and problems — ownership moves across. At small companies there is no SDR seat at all, so the founder writes them between other work.

The list works differently from the one marketing sends to. Newsletters and marketing campaigns go to people who agreed to receive them; cold email goes to people who never did. Rules differ by country, and commercial email often carries requirements around labeling and a working unsubscribe path, so it's worth one legal review before the first send.

Timing works on two levels. Across the week, reply rates run higher on Tuesday through Thursday mornings and lower on Monday mornings and Friday afternoons. This varies by industry, so split the sends for a couple of weeks and settle it with your own numbers.

In the deal flow, cold email sits at the very front. Volume is what separates it from the phone, which also means a wrong list produces wrong results that much faster. Start at 50 messages a batch, watch the reply rate, and only move to 500 once it clears 3 percent.

"300 cold emails went out and we got four replies. I think we start again from the subject line."

The reply rate is around 1 percent, under the bar, and the diagnosis points at the subject rather than the list.

"Let's skip cold email on this one and go through a warm intro. Our founders can connect."

An introduction through someone known is available, so the first touch should change form.

"The sending domain is still warming up, so we cap this week at 30 a day."

A new domain hasn't built enough reputation yet, and sending more risks the spam folder.

At Pagedeck, Sofia builds next week's list of 200 companies every Monday. She started with a single body for all of them and the reply rate wouldn't move off 1 percent. So she split the list into remote-first companies and office-based ones and changed only the opening line.

Remote companies got a line about notes scattering until the same discussion happens twice. Office-based companies got a line about decisions made in meetings never reaching a document. A month later the remote reply rate was 4 percent and the office one hadn't moved, so Sofia dropped the office list.

The most common belief is that email is free, so send more of it. The marginal cost of one more message really is close to zero. But as unopened, deleted messages pile up, providers start routing that domain to the spam folder, and then the well-written emails stop arriving too. It's a resource that wears out as you spend it — spend it all at once and there's nothing left next month.

The second is treating a merge field as personalization. Recipients get several of those a day and can tell from the first line. What actually works isn't their name, it's one line that's true only of their company: a recent job posting, a feature they shipped, an interview their founder gave. Finding it costs two or three minutes per company. Skip that to make the list ten times longer and replies go down, not up.
