The Growth Loop: Newsletter Feeds Twitter Feeds Newsletter

The Story

Harry publishes a Twitter thread several hours before the newsletter goes out. The newsletter then links to that thread and asks subscribers to like it. “Without that little line in the email which got it moving, it wouldn’t have snowballed originally.” (Source 3).

A documented example: on July 24, 2020, a Twitter thread was published at 1:53pm, then the newsletter went out later that day directing subscribers to engage with it (Source 2).

The mechanism: newsletter subscribers receive requests to “like” the accompanying Twitter thread. Twitter engagement signals value to the algorithm, increasing visibility. New people discover the thread, follow Harry, and then subscribe to the newsletter, completing the loop (Source 1).

This inverts conventional marketing advice. Instead of funneling all audiences to a single destination (the website), Harry sends people between channels. “Keep people on your website” represents outdated marketing wisdom according to the Growth In Reverse analysis. Harry embraces sending audiences between channels, recognizing that “a rising tide lifts all boats” across his entire ecosystem (Source 1).

Harry’s 3-step content repurposing methodology: (1) extract tips from articles before publication, share across platforms individually; (2) create a Twitter thread on publication day with images adjusted to Twitter dimensions (1 by 1.77); (3) send the full article in the newsletter with the Twitter thread link, asking subscribers to like it (Source 3).

“People don’t want to just click on a link on Twitter. People use Twitter to scroll through Twitter.” (Source 3). So the Twitter thread is self-contained content, not just a link to the article.

“I think a lot of my Twitter audience don’t even know that there is a website.” (Source 3).

Lesson for Creators

Most creators treat platforms as funnels pointing to one destination. Harry treats them as a loop where each platform feeds the others. The key insight is that your email subscribers are your most engaged audience. Asking them to boost a social post creates a concentrated signal that algorithms reward with broader distribution. The newsletter isn’t just a content delivery tool. It’s a distribution weapon for every other platform.
