What Gets Blocked
Blocking example.com blocks:
- sales@example.com
- info@example.com
- randomuser123@example.com
- ANY address @example.com
Format Rules
| ❌ Wrong | ✅ Correct |
|---|---|
| http://example.com | example.com |
| https://example.com | example.com |
| www.example.com | example.com |
| mail.example.com | example.com |
When to Use
- Multiple spam emails from same domain
- Random usernames (abc123@, xyz789@)
- Known spam domains
- Domains you'll never need emails from
Common Issues
Blocked legitimate emails
- Review blocked domains list regularly
- Remove domains if expecting emails
- Use email blocks for specific addresses instead
Spam from subdomains
Blocking example.com doesn't block mail.example.com. Block each subdomain separately.
Similar domain variations
Spammers may use: examp1e.com, exampIe.com. Block each variation.
