What Makes an Email Address Valid?
Structure: local@domain
- Local part — The part before @. Can contain letters, numbers, dots, hyphens, and underscores.
- @ symbol — Exactly one is required.
- Domain part — Must be a valid domain with at least one dot (e.g., gmail.com).
- TLD — Must have a valid top-level domain (at least 2 characters).
Common Issues
- Missing @ symbol or domain
- Spaces or invalid characters
- Typos in popular domains (gmial.com, yahooo.com)
- Using disposable/temporary email providers
- Domain without a proper TLD
