Looking for somewhere to grow your newsletter? There’s a reason all of the biggest publishers promote on Twitter.

Ex-writer for the Hustle and owner of Newsletter Operator, Matt McGarry explains why in a recent post:

  • Twitter is a text-based platform with more people who read newsletters

  • Twitter ads have now been optimized for engagement and conversions

  • Ad impressions are cheap. Up to 5X cheaper than ads on Meta

The Newsletter Ad that Keeps Going Viral (Unpacked)

AI Tool Report is a newsletter on AI sharing the latest trends and industry updates. It has over 300,000 subscribers, including executives at Tesla, Microsoft, and Meta.


Its founder, Martin Crowley, uses his personal Twitter as its main promotional channel.


See the ad above? It has 1.4M impressions, 443 likes, 61 reposts, and 36 comments. But that isn’t the only time the ad went viral.

Martin has posted the same ad 3 times. The others getting 1.3M and 837K views.

#1 The Virality Formula

We all know the power of voice of customer (VoC) in copywriting. i.e. using the words of your audience.

The ad copy is simply a quote from a reader, with some slight modifications to power it up:

The power-up of the quote comes as it is transformed into the famous AIDA copywriting formula:

  • Attention (A)

  • Interest (I)

  • Desire (D)

  • Action (A)

With the action presented at the bottom of the post.


My boss thinks I’m an AI genius” – this shows the outcome of using the product. 

Other people thinking you’re a genius is the promise most of the top newsletters, including the Morning Brew, use in their marketing because it targets the transformation the reader goes through when reading the newsletter.


(I’m not) it’s because I read The AI Tool Report” – this overcomes an objection to the promised transformation that not all of us are geniuses.

Then it presents the newsletter as the mechanism that overcomes that objection.


(and they have no idea it exists)” – Knowledge is nice to have. But secret knowledge is enticingly desirable.


Below the ad image is a clear promise-based call to action (CTA).

#1 How to use the AIDA copywriting formula: begin with a transformational promise, overcome an objection, present your newsletter as the transformation mechanism, and finish with a desire.

# 2 The Ultimate Lead Magnet

As far as lead magnets go, few are more desirable than cheat sheets. They satisfy all of our 3 core desires: to get things faster, cheaper, and easier.

The prompts are shown bigger than everything else because most people struggle with prompting and they’re familiar with what it is.

The secondary elements, the “Key Terms” and “Key Features”, probably won’t be read by most of the audience. They mainly serve to make the cheat sheet look more robust.

Another version of the ad with a prompting calendar wasn’t as hot:

This is likely because a calendar illustrates work and AI is supposed to be a tool that reduces work. So it’s missing the “faster” and “easier” desirability factors.

#2 How to choose your lead magnet: see what others in your newsletter category are offering. Provide something that is free, makes your target reader’s life easier, and gets them a result faster.

# 3 The 45% Conversion Rate SignUp Page

The short size and format of newsletter signup pages requires some specialist conversion elements.

The AI Tool Report signup page has a number of strong elements:

  • Numbers to communicate the value (green and blue)

  • Social proof (blue and orange)

  • Transformation (red)

MilkRoad added the same elements to its signup page and increased conversions to 45%:

#3 How to structure your newsletter signup page for maximum conversions: use your newsletter’s promise as the headline, expand on the promise in the subheadline, and use numbers for social proof and to highlight the “ease” of getting the promise.

[BONUS] A Secret Martin Probably Doesn’t Want You to Know About…
