How to write a newsletter

To write a newsletter that keeps an existing list buying: pick the one problem you solve, tell it in a story worth finishing, and send often enough that your name means something before you ever ask for the sale. That’s the whole job. Most coaches skip straight to “growing the list” when the list they already have is the asset sitting untouched.

I started my newsletter career writing emails on Upwork for $5 an hour while instructing at the YMCA. When my gym job evaporated in 2020, email was the skill I doubled down on, and it went on to produce $15M+ in tracked client sales. This is the plan I run when a coach already has a list, and it has gone quiet, or it has never really been asked to buy anything.

Rule one: monetize the list you have before you grow it

I once demonstrated this on camera with two jars. A 20,000-subscriber list running a $40,000 promotion earns about $1 per subscriber. A 2,000-person list selling ten $5,000 packages earns $25 per subscriber, from one tenth of the audience. Same channel, 25x the efficiency.

Here’s the thing: most coaches with an existing list assume the problem is size. It rarely is. If you can’t take the 500 people already subscribed from “who is this again?” to “take my money”, adding 5,000 more names just scales the silence. Fix the newsletter first, grow it second. The revenue plays live in the coach’s email marketing guide.

Re-introduce yourself before you sell anything

If your list has gone cold, the temptation is to jump straight back in with an offer. Don’t. Send one honest email first: where you’ve been, what changed, why you’re back. Readers forgive a gap; they don’t forgive being sold to by someone who vanished without a word.

Look, I totally get why coaches avoid this email. It feels like admitting a mistake in public. But the alternative, silently resuming broadcasts as if nothing happened, reads as tone-deaf to anyone who noticed the gap. One honest paragraph resets the relationship faster than a month of pretending it didn’t happen.

The simple newsletter loop, applied to a list you already have

Story, then lesson, then soft offer, then data, then a better story next time. That loop runs the same whether your list is brand new or three years old and half-asleep. The difference with an existing list is you already have the raw material sitting in your inbox and your CRM:

1. Who am I actually writing to? Look at who has bought, replied, or booked a call. That’s your real reader, not the persona from your original launch plan.
2. What’s the offer now? It may have changed since you built the list. Say so plainly rather than assuming old subscribers already know.
3. What do the emails talk about? The objections standing between this specific audience and the current offer, which you can hear directly in sales-call recordings and old replies.
4. What’s the re-engagement hook? One story that explains the gap or the shift, so new content doesn’t feel like it dropped out of nowhere.
5. What’s the cadence? Consistent, sustainable, and public: tell your list when to expect you, then show up.

Write like a person, not a newsletter

The most profitable emails I’ve written wrapped a boring lesson inside a story readers wanted to finish: a client’s midlife-crisis drum kit became an email about delegation, and it sold. An existing list has already met the version of you that sounded like a company. Give them the version that sounds like a person, and the open rates follow, because readers buy the person, not the information.

Now I know what you might be thinking: won’t going personal after a long silence feel strange? It will, for one email. Then it becomes the reason people start opening again.

Don’t wait years on deliverability (I did, for three)

SPF, DKIM, DMARC, seed tests, list scrubbing: it sounds like jargon, so I ignored it for three years. It’s no longer optional either: Google’s own sender guidelines require SPF, DKIM and DMARC for bulk senders, and mail that fails those checks gets rejected or filed as spam. Then one client’s open rate went from 10% to 24% in 60 days mostly on deliverability fixes, and the sales followed immediately after. This matters more, not less, on an existing list, because a quiet list often has a hidden deliverability problem underneath the content problem. If your restart email lands in spam, none of the story-craft above gets read. The plain-English setup is in the deliverability guide.

Build a proof bank from the customers you already have

Three weeks into managing my first newsletter I’d used every testimonial the client had. So I learned to farm proof: YouTube comments, coaching-call wins, community posts, always with permission, which is the golden rule I learned the hard way. An existing list is sitting on proof a brand-new one doesn’t have yet: past buyers, finished results, real quotes. File each piece by the objection it answers, and you’ll never face a blank screen before a promotion again.

Better still, interview past customers directly. I’ve done 25+ for one creator; those interviews took his course from 2 to 3 sales a week to 2 to 3 a day and now power a webinar converting at 5% on evergreen. AI can scrape Reddit for language, but your own customers hold your exact marketing language, and this is a personal-brand business: people buy you.

How often to send, and what to send it about

The good news is that cadence and content are the two levers, and you already have data on both. For cadence, see how often to send marketing emails: daily where you can sustain it, because familiarity compounds faster than any single “perfect” email ever will. And if you’re worried daily sending burns a list, MailerLite’s cadence data shows daily senders hold click rates (4.97% against 4.87%) and unsubscribe rates (0.36% against 0.38%) right alongside weekly senders. For the line that gets the email opened in the first place, the subject line rules live in email subject lines that get opened.

Frequently asked questions

How do I write a newsletter for a list that already exists but rarely buys?

Treat it like a restart, not a first date gone cold. Re-introduce yourself with one honest email about why you've been quiet, then get back to a sustainable cadence and let the offer show up naturally inside the story, not bolted onto the end.

How often should I write to my existing list?

Daily, or as close as you can sustain. A list that already knows you forgives frequency; it does not forgive silence. Daily sending also produces conversion data seven times faster than weekly, and batching with an AI system removes the workload excuse.

My list is small. Is it worth writing a newsletter for 500 people?

Yes, and the size is not the constraint you think it is. I have watched a 2,000-person list out-earn a 20,000-person list on efficiency: $25 per subscriber against $1. Learning to monetize the list you have is the skill that later earns from a bigger one.

What should I write about if my list has gone quiet?

Your life is the content: client conversations, mistakes, opinions, the book you threw across the room. Wrap one lesson inside one story per email. A quiet list rarely means the offer is wrong; it usually means the emails stopped feeling like a person.
