How does Caroline Chambers use ManyChat to grow her Substack?

Chambers includes a prompt in her Instagram cooking video captions asking viewers to comment the dish name to receive the recipe. ManyChat automatically sends a DM with a Substack link the moment someone comments, routing them toward a paid subscription.

What is ManyChat and how does the comment-to-DM mechanic work?

ManyChat is a comment-automation platform that monitors Instagram posts for specific trigger words. When a user types the designated word, ManyChat fires a pre-written direct message instantly, moving the conversation from a public feed into a private channel.

Why do creators use Substack as a destination rather than keeping audiences on Instagram?

Substack gives creators a direct financial relationship with subscribers that Instagram followership does not provide. A subscriber list belongs to the creator; a follower count belongs to the platform. Substack also offers built-in paid subscription tools for food writers specifically.

Can creators outside of food use this Instagram-to-Substack funnel strategy?

Yes. The core logic works for any creator whose content has a discrete, requestable output such as a template, resource list, or tutorial step. The key is pairing a zero-friction comment prompt with automated delivery of that output via DM, then linking to a platform the creator controls.

Key Takeaways

Chambers uses Instagram video as a conversion trigger, not a destination: a comment prompt plus ManyChat automation routes viewers directly to a paid Substack subscription.
Owning the subscriber list on Substack is the strategic core. A follower count belongs to the platform; a subscriber relationship belongs to the creator.
The comment-to-DM funnel structure is replicable in any niche where content has a discrete, requestable output with near-zero friction to claim.

Imagine posting a cooking video on Instagram, writing one word in the caption, and watching thousands of people get automatically redirected into your paid subscription business within seconds. That is not a growth-hack fantasy. That is the documented operating model of Caroline Chambers, described by Business Insider as Substack's top food writer and the architect of a 7-figure subscription business. The architecture is counterintuitive enough to deserve a slow walkthrough, because it flips the standard creator assumption completely: social video is not where the value lives. ## The Funnel Nobody Talks About Most creators treat social video as the endpoint: post, collect views, run ads against those views, repeat. Chambers treats Instagram video as a conversion trigger. According to Business Insider's reporting by Sydney Bradley, on many of Chambers' cooking videos she includes a simple direction in the caption: comment the name of whatever she is cooking and she will send the recipe. Within seconds, users receive a direct message from her account with a link to her Substack recipe. The social feed is the top of a funnel; the paid newsletter subscription is the bottom. The tool doing the behind-the-scenes work is ManyChat, a comment-automation platform that monitors for specific trigger words and fires off pre-written DMs the moment someone types them. As Lauren Lomsdale explains at Aura Digital Consulting, this mechanic turns passive scrollers into warm leads by moving the conversation out of the public feed and into a private, one-to-one channel. The perceived intimacy of a direct message is real even when the message is automated, and that shift in context changes how people relate to the link they receive. They asked for it. That asymmetry matters. The sequence Chambers has built is worth mapping explicitly, because each step does a distinct job. ## Why Substack Is the Right Landing Pad The choice of Substack as the destination is not incidental. Substack positions itself as a platform built on a direct financial relationship between writers and readers, and it has actively cultivated food writers as a target vertical, offering a dedicated food-writers landing page and fellowship programming, according to Substack's own resources. That direct relationship matters strategically: when someone subscribes through Chambers' DM link, Chambers owns that subscriber relationship in a way that an Instagram follower never quite represents. The follower count belongs to the platform; the subscriber list belongs to the writer. Substack's own masterclass guidance for video creators, hosted by writer partnerships staffer Randa Sakallah, frames Substack explicitly as an economic engine that can support any creative person regardless of format, and specifically addresses how to market a Substack to an off-platform audience. Chambers' Instagram funnel is a textbook execution of exactly that off-platform marketing philosophy. She is not trying to grow on Substack by using Substack's internal discovery tools alone. She is using the platform with the largest reach (Instagram) to fill the platform with the most durable economics (Substack). ## The Broader Shift This Reflects Chambers' strategy is a sharp response to a structural problem that writer Julia Alexander identified in her essay at Posting Nexus: attention is consolidating into fewer apps designed to extend session time, and that architecture is not inherently conducive to creators, even though creators are the reason people show up. If your livelihood depends entirely on a platform's algorithm deciding to show your posts, you are a tenant paying rent in someone else's building. The DM funnel is a workaround: it uses the attention economy's own mechanics (the viral comment prompt, the dopamine hit of a personalized message) to route people off-platform and into a relationship the creator actually controls. This is also why the food vertical is particularly well-suited to this model. Recipes are discrete, high-utility objects. A viewer who wants that specific dish has immediate, concrete motivation to take the one-step action of typing a word in a comment box. The friction is almost zero, which means conversion rates can be high even if the eventual paywall on Substack is real. Chambers has found a category where the free sample (the recipe preview, the video of the finished dish) is genuinely compelling enough to justify the ask. ## What Creators Can Learn From This The Chambers model is replicable in structure even if the exact numbers will differ. The core logic has three components: create short video that demonstrates clear, immediate value; attach a zero-friction call to action that triggers automated delivery of that value via DM; and ensure the DM destination is a platform where the creator controls the subscriber relationship and can eventually charge for deeper access. The specific vertical does not have to be food. The same architecture works for any creator whose content has a discrete, requestable output: a template, a resource list, a tutorial step, a reading recommendation. What is worth watching next is whether Instagram's own platform policies keep pace with how heavily creators are now relying on third-party automation tools like ManyChat. Platforms have a complicated history with automation that benefits creators rather than the platform itself, and any policy shift there would change the math on this funnel quickly. For now, Chambers' system stands as one of the cleaner examples of a creator using social reach as infrastructure rather than as an end in itself. The social feed is the doorbell. Substack is the house. ## Sources - How Substack's top food writer is using video to drive subscription growth in her 7-figure business - Business Insider(opens in new tab)
