Free & Role Email Checker
Find out whether an address belongs to a person at a company, a shared team inbox, or a free consumer provider.
How it works
Role addresses (info@, sales@, support@) reach a team, not a person. They're fine for transactional mail but hurt cold-outreach reply and complaint rates.
Free-provider addresses (Gmail, Yahoo, Outlook) are normal for consumers but a weak signal for B2B leads.

Frequently asked questions
Should I email role accounts?
For transactional and support mail, yes. For cold outreach, they convert poorly and attract more complaints.
