The threat to @beehiiv isn't marc lou (guy's a jester). The actual threat to beehiiv is that humans will stop reading their email. AI agents don't read newsletters. Even today, the Apple summary front-runs the need to open for a percentage of readers. This means the ad model for newsletters is gone in 3 years. The conversion math also becomes tougher and tougher, even with a huge list. If everyone is using Claude/Muse/Grok as their LifeHQ (which they will), the only newsletters that get read will be personality/opinion driven (for fun). The "own your audience" frame also dilutes when the layer between your words and the human buyer is designed to avoid consuming it. This is not a beehiiv problem, it's an email problem in general. Beehiiv is diversifying into other products, which is smart. But one of the core tenets of audience building (just get their email and you're golden) is starting to weaken.
