CleanSignups helps businesses prevent fake signups, reduce bounced emails, and improve email deliverability with real-time email verification. Beyond standard validation, it detects disposable emails, spam traps, catch-all domains, mailbox status, domain health, SMTP issues, DNS records, and AI-powered risk analysis. Easily integrate with forms, CRMs, SaaS apps, and APIs to keep your customer database clean from day one.
Hey Product Hunt! 👋
I'm Shivaji, founder of CleanSignups.
THE BACKSTORY
We were running a SaaS product and noticed something painful — about 25% of our free trial signups were using disposable emails like 10MinuteMail and Guerrilla Mail. They'd grab the free trial, never convert, and our email campaigns to them would bounce, damaging our sender reputation for everyone else.
We realized fake signups were costing us through wasted ad spend, higher email platform costs, and lower deliverability. That experience led us to build CleanSignups.
WHAT WE DO DIFFERENTLY
Most email verification tools validate after the damage is done. We verify at the moment of signup — in real time — so fake emails never enter your database in the first place.
A single API call returns:
→ Whether it's disposable (we track 150,000+ throwaway domains, updated daily)
→ Domain health (MX, SPF, DMARC, age)
→ Quality score (0-10 risk assessment)
→ Spam trap and blacklist flags
→ Webhook alerts for real-time monitoring
FOR NON-DEVELOPERS
We have direct integrations with Mailchimp, HubSpot, ActiveCampaign, Brevo, SendGrid, GetResponse, Zapier, Google Sheets, and more. Connect, import your list, clean it — no code needed.
