Chain Emails

What it was

Chain emails spread through fear, luck, jokes, prayers, friendship tests, and social pressure.

Why people remember it

• They were crude growth loops.
• The message recruited the next sender.
• Modern share prompts are cleaner, but the emotional levers are older than social apps.

What replaced it

Usually a platform feature, a private analytics dashboard, a cleaner app pattern, or a feed. The behavior rarely disappears; it gets renamed and absorbed.
