I use this for the bi-weekly newsletters - the investor update, the customer and prospect update, and the candidate newsletter - plus any nurture send to a segment. It pulls the last two weeks of real wins, writes each newsletter in the right voice, and stages it as a MailerLite draft for me to approve. I reach for it on the newsletter cadence, and any time I want to warm a list rather than cold-email it.

I use this for the bi-weekly newsletters - the investor update, the customer and prospect update, and the candidate newsletter - plus any nurture send to a segment.

What the AI actually does

You trigger one newsletter. The AI reads the wins from the last fortnight, writes the send in the correct voice for that audience, brand-checks it, then stages it as a MailerLite campaign pointed at the right group. The manual version is gathering wins by hand, writing from a blank page, then wrestling the email editor. This is a draft waiting for your read.

The split holds up against how the tools work. MailerLite is a full email platform - a drag-and-drop editor, audience groups and segments, and an automation builder that can trigger sends off actions like joining a group or clicking a link - so the send, the segment and the schedule all live there. The wins live in Airtable and the wiki. AI is the layer that reads one and stages the other.

The tools and APIs you need

The right prompts

Draft this cycle's newsletters

```
/meritt-marketing
Write this cycle's customer + prospect update.
Pull wins from the last two weeks (wiki, Airtable placements and shipped
features). My voice. Then stage it as a MailerLite draft to the
customers group and tell me the subscriber count - do not send.
```

Nurture a specific segment

```
We just shipped [feature]. Draft a short nurture email to the prospects
segment in my voice, create it as a MailerLite campaign, and show me the
draft and the audience size before anything goes out.
```

How to do it

Trigger the skill

for the newsletter you want - investor, customer, or candidate.

Let it gather the wins

from the last two weeks across the wiki, [Airtable](https://www.airtable.com/) and notes.

Let it write in the right voice

for that audience and brand-check itself.

Review the draft

This is the human gate - read it, tighten it.

Confirm the staging in [MailerLite](https://www.mailerlite.com/)

It creates the campaign and points it at the right group or segment. Check the audience and the subscriber count.

Approve and schedule

the send yourself.

See the difference

Weak

Doing it by hand: write newsletters and nurture sends with ai the manual way - slow, and the first thing to slip when you are busy.

Strong

With AI: you describe what you want in plain English and it does the work, on-brand, in minutes.

Let AI carry the heavy lifting; you keep the judgement and the final say.

How you'll know it's working

  • Three newsletters that sound like the people who would have written them, grounded in real wins from the last fortnight.
  • Each one staged against the correct audience in MailerLite, with the count confirmed.
  • Nothing sends until you say so.
  • The whole cycle is a review job, not a writing job.

Questions people ask

What is AI newsletter writing?

Using an AI assistant to turn your real, recent wins into a finished newsletter in the right voice for each audience, then stage it in your email tool - so the gathering, the drafting and the loading happen for you, and you do the reading and the approving.

Do I still need MailerLite?

Yes - it is the send layer. [MailerLite](https://www.mailerlite.com/) holds the audience groups, the editor and the [automation](https://www.mailerlite.com/features/automation) that actually delivers the email. AI gathers the wins and stages the draft inside it; MailerLite is where the send and the schedule live.

Will it send without me checking it?

No. The draft stages against a segment and stops there. You read it, confirm the audience and the subscriber count, then approve and schedule the send yourself. Audiences are engagement-gated, so you are warming an engaged list rather than blasting a cold one.
