As accurate as sending an email without sending one. Clear Deliverable or Undeliverable verdicts with a confidence score.
Trusted by 2,000+ Enterprise Teams
Catch-all domains accept mail for any address and hide whether a specific mailbox exists. Most verification tools guess. Our platform returns a Deliverable or Undeliverable verdict plus a confidence score using advanced algorithms and a layered signal set.
Clear action per address (Deliverable, Undeliverable, Risky) and recommended next steps.
0 to 100 confidence score with recommended routing logic for your campaigns.
Single email enrichment: name, role and company signals. (Beta for bulk).
Fast CSV processing and real time API checks. Webhooks for automation.
Seamless sync with your CRM, SFTP access, Zapier, and Make integrations.
Upload CSV, paste a list, or send single checks via the web UI or API.
Advanced algorithms inspect MX/DNS fingerprints and SMTP patterns to classify deliverability.
Segment by status, export or sync to CRM, or route leads only when Deliverable.
REST API for single checks and bulk uploads. Enterprise plans include throughput SLAs and secure SFTP access.
Full visibility into your verification results and list health.

"The confidence score helped us decide who to keep instead of guessing. Catch-alls stopped being a mystery."
"Bounce rates dropped by 60% in our first campaign. The deep-SMTP signals are far superior to standard API pings."
"Integrated the API in 30 minutes. We now auto-verify every form submission before it hits our CRM."
We analyze time-to-first-byte (TTFB), banner greeter latency, and specific SMTP error codes to distinguish between a firewall sinkhole and a real inbox.
