Email Newsletters with Claude

The one marketing channel you own outright and how to write it in under 30 minutes a week

Every social platform you post on is rented land.

Instagram changes the algorithm and your reach drops 60% overnight. Twitter and X introduce paid features that bury non-paying accounts. A platform disappears, as Vine did, as Google+ did, as any number of things that seemed permanent and were not.

Email is the one channel you own outright. Nobody decides who sees your email except the person who opened it. Nobody can take your list away from you. If you move platforms, change your name, or start an entirely different thing next year, you take the list with you.

This lesson shows you how to set up a simple newsletter, write it with Claude in under 30 minutes a week, and grow a list that belongs to you permanently.

What Platform to Use

Beehiiv is the best free option for creators and builders. Free up to 2,500 subscribers, no transaction fees, built-in analytics, and it looks professional out of the box. Start here unless you have a specific reason not to.

Kit, formerly ConvertKit, is the next step up for more complex automations. Free up to 10,000 subscribers with basic features.

Substack is free and simple but takes a 10% cut if you monetise. Good if you want built-in discovery.

For most people starting out, go to beehiiv.com, create a free account, create a publication, and set up your subscribe form. It takes 15 minutes. Do it before running any social content that references your newsletter.

What a Newsletter Actually Needs

You do not need a masterpiece every week. A working newsletter has three things.

One theme per issue. Not a grab-bag of five things. One idea explored properly. Readers should be able to summarise your issue in one sentence.

A personal angle. Something happened this week. Something you noticed. A mistake you made. A client said something interesting. That is the opening. A newsletter that is just information reads like a blog post. A newsletter with one real specific thing that happened this week reads like a human being wrote it.

One ask. Reply to this email, check out this link, or nothing at all. Not five asks at the end of every issue. One or none.

The Newsletter Structure

Every issue follows the same structure.

The subject line is a hook that is short, specific, and has no clickbait. The opening is 2 to 3 sentences that are personal and set up the theme for this issue. The body is the main idea, story, or lesson drawn from one of your four content pillars. The takeaway is one sentence covering the thing to remember from this issue. The ask is one clear next step, or you close without one if this is a trust-building issue.

Keep the whole thing under 300 to 400 words. That is short enough to read in 2 minutes on a phone. Most newsletters are too long.

The Newsletter Writing Prompt

Before running this prompt, answer one question: what actually happened this week that connects to this week's idea? A conversation, a mistake, a win, something you noticed. Even one specific sentence of real context makes the output ten times better.

Using @MARKETING.md for my audience and voice — write a newsletter issue.

THIS WEEK'S IDEA: [ONE IDEA FROM CONTENT-IDEAS.MD]

WHAT ACTUALLY HAPPENED THIS WEEK (use this in the opening):

• [ONE REAL THING — a client conversation, a mistake, something you noticed.
• If nothing happened, write "nothing specific — write it as a straight lesson."]

Write the full issue in this structure:

1. Subject line (under 55 characters — use hook principles from the hooks lesson)
2. Opening (2 to 3 sentences, personal, sets up the theme)
3. Body (the main idea — 150 to 200 words, one concrete example or story)
4. Takeaway (one sentence — what to remember)
5. Ask (one thing to do, or close without one)

Rules:

• Write it like an email to one real person and not an announcement to a list
• Apply all voice rules from @MARKETING.md
• No corporate newsletter voice, no "I hope this email finds you well,"

no "in this issue," no summarising what you are about to say

• The opening should start with the real thing that happened, not a headline

What to Do If Nothing Happened This Week

Some weeks are quiet. Nothing interesting happens. That is fine and you should not force a story that is not there. In the prompt above write "nothing specific — write it as a straight lesson."

The issue will be more impersonal without a personal angle but a useful lesson without a story beats a made-up story every time. Readers can tell when the real thing that happened did not actually happen.

How to Grow the List

The landing page course gave you the mechanism: a lead magnet with an email capture form. The newsletter is where those emails go.

The simplest way to grow your list from zero is to mention your newsletter in your social content once or twice a week but not every post. Add your Beehiiv subscribe link to your bio on every platform. If you have a landing page add an email signup section to it. When someone engages with your content by replying to a post or sending a DM, mention the newsletter in your reply.

What does not work is chasing every follower into the funnel. The goal is that the people who are genuinely curious can find their way to the list, not that you push every reader into it before they are ready.

Your Action Right Now

If you have not already, go to beehiiv.com and create your publication now. It takes 15 minutes.

Then pick one idea from your backlog and one real thing that happened this week. Run the newsletter prompt above. Read the draft out loud. Does it sound like you wrote it? If not, use the voice correction method from the voice lesson.

Send your first issue this week. Even if your list is one person, which is yourself. The habit matters more than the audience size at the start.
