Great PostHog Feature Email

PostHog’s email promoting their A/B testing tools nails one thing most SaaS emails miss: personality. The little hedgehog kicking back after launching an experiment makes data testing look, well, fun.

Marketing analysis

This email uses humor and simplicity to turn a technical concept (A/B tests) into something relatable. Instead of listing product specs, it sells the feeling of using the product—ease and relaxation.

Why it works

• Headline plays with curiosity and humor (“A great excuse reason to put your feet up”)

• Visual storytelling instantly draws a smile

• Focused copy: one message, one call-to-action

• Brand voice feels human, not robotic

• The “lazy” theme is actually a stealth productivity hook

Examples

• Notion’s quirky release emails make feature drops feel fun and personal

• Slack uses playful illustrations to simplify technical updates

• Zapier’s emails highlight “work smarter, not harder” angles with cheerful visuals
