emails that get replies.

email consistently converts better than any social channel and gets a fraction of the attention, largely because it is unglamorous. nobody shows a colleague their newsletter open rate the way they show a video that did well.

it also fails in a predictable way. most business email is a broadcast about the business — a new service, an award, a monthly round-up — sent to people who signed up for something else, and it trains the list to stop opening.

the fix is not better design or a stricter schedule. it is deciding that each email exists to be useful to the person receiving it, which changes what goes in it and usually makes it shorter.

— 01one email, one useful thing.

the discipline that fixes most email is a limit of one idea per send. one thing worth knowing, one offer, one story, one question. an email covering five topics gets skimmed and none of the five lands.

and the thing should be useful to the reader rather than newsworthy to you. a practical answer, a genuinely good recommendation, a lesson from a project, a warning about something in the market. company news is only interesting to people who already care, and the list is mostly people who do not yet.

this is also what makes replies possible. a broadcast invites nothing; an email with one idea and a real question at the end gets answers, and those answers are the most valuable market research a business can get for free. read every reply, and answer them yourself for the first few months — the patterns in what people ask will change what you sell as well as what you send.

reply rate is worth tracking for that reason. it is a better health signal than open rate, which platform changes have made increasingly unreliable. clicks through to the one thing you asked about are the other honest number, because they measure whether the email did its job rather than whether it arrived.

— 02write it like a person.

plain text from a named person outperforms a designed template in almost every test we have run. the design signals a campaign, and a campaign gets filed. a message that looks like it came from someone gets read.

so send from a person's name, keep the formatting minimal, and write in the register you would use to a client you know. no headers, no stock imagery, no three-column layout unless you are a retailer sending products, where the rules are genuinely different.

subject lines carry most of the outcome. specific and slightly understated beats clever — "the pricing question every client asks" gets opened; "unlock your growth potential 🚀" does not. and never write a subject line the email does not deliver on. the short-term open is not worth the long-term cost of a list that stops trusting your subject lines.

— 03send less often than you think, consistently.

the two failure modes are silence and volume. a list emailed twice a year has forgotten who you are; a list emailed weekly with nothing to say unsubscribes at a rate that is expensive to replace.

monthly is the safe default for most businesses, fortnightly if you genuinely have something each time. what matters more than frequency is consistency — a predictable rhythm builds an expectation, and an expectation is what gets an email opened before it is read.

and segment minimally rather than elaborately. customers versus prospects is usually enough to justify different content, and complicated segmentation schemes tend to collapse under the effort of maintaining them. one exception is worth the effort: a separate track for people who bought once and have not bought again, because that is the group most likely to respond to a single well-timed message.

— 04build the list honestly.

a small list of people who chose to be there outperforms a large one assembled from business cards and scraped addresses. bought lists damage deliverability and produce nothing, and in most jurisdictions they carry a compliance problem as well. a poor sender reputation also affects the emails you actually need delivered, which makes this a business risk rather than a marketing one.

the reliable sources are all voluntary: customers at the point of purchase, an offer worth an email address, event attendees who agreed, and people who asked. say what they will receive and how often, then do exactly that. a smaller list that opens is worth more commercially than a large one that does not, and it costs less to send to.

and treat the list as a business asset with a value. it is the only audience that cannot be throttled by a platform change, which is why we treat it as part of the core plan rather than a separate channel — and why the reply handling matters as much as the send.
