CheckMail1
Real-time email verifier that checks if Gmail & iCloud exist
Most email verifiers only check syntax and DNS — they can't tell if a Gmail or iCloud address actually exists. CheckMail1 uses browser automation to simulate real login attempts on Gmail, iCloud, Yahoo, Outlook, and 20+ providers. • Browser-based verification for major providers • SMTP check for business domains • Bulk CSV upload • API access • Pay-as-you-go pricing Perfect for email marketers and developers who need accurate lists.
Hey Product Hunt! 👋
I built CheckMail1 after getting frustrated with email verifiers that only check syntax and DNS records — they'd mark fake Gmail addresses as "valid" because the domain exists.
CheckMail1 actually opens a browser and simulates a real login attempt to check if the account exists on Gmail, iCloud, Yahoo, Outlook, and 20+ other providers. It's the same thing a human would do manually, just automated.
Use cases I've seen so far:
• Cleaning cold outreach lists before campaigns
• Validating leads from signup forms
• Removing hard bounces before they hurt sender reputation
Happy to answer any questions about how the browser-based verification works! 🚀
