Reddit: 12M undeliverable emails identified in three months
Reddit used real-time verification after bounce signals and during key onboarding paths—recording results without automatically discarding valid users.

The challenge
What was getting in the way
High daily volume (notifications, password resets, community updates) mixed with bounce noise made it hard to know which addresses were truly undeliverable vs. temporary failures.
The approach
How verification helped
Verification API results were logged for opt-in, event, and onboarding flows so teams could investigate bounces with structured data rather than guessing.
