Frequently Asked Questions

What does this tool detect?

Why should I filter free email addresses?
In B2B marketing and sales, leads with business emails (user@company.com) are typically higher quality than free email users (user@gmail.com). Filtering helps prioritize outreach, segment lists, and improve conversion rates.

What counts as a disposable email?
Disposable emails are temporary addresses from services like Mailinator, Guerrillamail, Tempmail, and 10MinuteMail. They are often used to bypass sign-ups and have no long-term value for marketing.
Can I check a whole list at once?
Yes. Switch to Bulk Mode and paste up to 10,000 email addresses. The tool classifies all of them and provides breakdown statistics with the option to export filtered lists or CSV.
Is my email list stored anywhere?
