Academic Email Domain Verification

• Validates emails against a curated list of global university domains

What happens if the email format is invalid? Invalid email formats are rejected before domain matching to ensure reliable results.

Is the university list customizable? Yes. The domain dataset can be updated or extended by modifying the universities data file.

Does it store or log emails? No. Emails are processed in-memory for validation and are not persisted.
