Continuum API - Email verification that doesn't stop after signup

by•
Most email verifiers check once and move on. Continuum API verifies emails in real time AND monitors them continuously What's different: - 9 verification checks in a single API call - Continuous monitoring with configurable recheck schedules - Signed webhooks when email status changes - Bulk CSV verification up to 100k emails - Self-serve — API key in seconds, no demo required Built for developers who want email health as infrastructure, not a one-time list cleaning tool.

Hey Product Hunt 👋 I'm Sumeet, founder of Continuum API and the parent company SignalPulse Technologies. I built Continuum API because every email verifier I used had the same problem — they verify once and stop. But email health changes. Addresses get abandoned, domains change MX records, mailboxes get reassigned. Nobody tells you. Continuum API fixes this with continuous monitoring. Verify an address, enroll it in monitoring, receive a signed webhook when its status changes. Your CRM stays clean automatically. Free until May 17 — would love your feedback on what's missing for your use case.
