Where this starts
Instagram creators skew newsletter detection, for a reason specific to them. Any newsletter detection method has to survive this: Instagram creators split their audience across posts and Reels and Stories, and only one of those is visible from outside. What catches people out on Instagram creators, newsletter detection included: bought followers are more common here than on any other network. Link in Bio Newsletter Checker carries 1 ready made setup for newsletter detection on Instagram creators.
What is at stake
The signal on Instagram creators sits one click behind the profile, which is exactly where nobody keeps looking at volume.
Traditional Search Tools
- The Reels tab, for Instagram creators. Free, and recent Reel views next to the follower count show whether anyone is watching.
- Substack and beehiiv discovery pages. Each platform lists its own writers by category. Free, and blind to every creator on a different platform or a self hosted list.
- SparkLoop and newsletter ad networks. They know the newsletters in their own network, with audience sizes. The network is the boundary, and most creators are outside it.
- Asking the creator. The answer is accurate and the list size is often generous. It takes a conversation per creator, which is exactly what a list was meant to avoid.
- Click through every link page. Open the link in bio for each creator and look for a signup form or a link to Substack, beehiiv or Kit. Note the platform. Two to four minutes a creator, longer when the link page needs a browser to load.
