Why block disposable emails?
Fake signups waste resources
Users with disposable emails rarely convert. They're often just testing, abusing free trials, or creating spam accounts.
Skewed analytics
Disposable email users inflate your user count but hurt engagement metrics. Get accurate data by filtering them out.
Fraud prevention
Fraudsters use throwaway emails to avoid detection. Block them at signup to reduce chargebacks and abuse.
