What should I use to detect disposable, temporary, and role-based emails?

Use an email intelligence / verification service that specifically flags:

• Disposable / temp email domains
• Role-based addresses like info@, support@, admin@, sales@
• Sometimes also catch-all, free provider, and risk scores

Good options

• Kickbox – email verification with disposable and role-based detection
• ZeroBounce – strong for disposable, role-based, abuse, and catch-all checks
• NeverBounce – good for validation and some risky-email detection
• Mailboxlayer – lightweight API for validation and disposable detection
• Abstract Email Validation API – includes disposable and role-based flags
• Hunter Email Verification – useful if you already use Hunter for enrichment

If you want to build it yourself

You can combine:

1. A maintained disposable domain blocklist
2. A list of role-based local parts (admin, support, billing, etc.)
3. SMTP/verification checks for deliverability

What to look for in the API

Make sure it returns fields like:

• disposable
• role
• free
• catch_all
• valid
• deliverable

Practical recommendation

If you want the simplest robust option: ZeroBounce or Kickbox.

If you want, I can also give you:

• a comparison table of the top providers, or
• a sample implementation in Python/Node.js.
