PostHog nailed this email. They didn’t just announce lower prices—they made it funny, visual, and insanely clear why it matters.
The email leads with a bold statement (“We’ve decided to make less money”) that instantly grabs attention. Then they back it up with a chart that makes the comparison to competitors impossible to ignore. The cartoon fire adds humor and personality while softening the “we’re slashing prices” message.
