Stop Discarding Catch-all Emails
Catch-all domains accept all mail — which means standard verifiers give up. VeriMails scores every catch-all address from 0.0 to 1.0 so you send where it matters, not everywhere.
Smarter handling of catch-all domains
Turn an uncertain result into actionable data with probability-based scoring.
0.0–1.0 Confidence Score
Every catch-all address receives a deliverability score based on domain patterns, historical behavior, and mailbox signals.
Catch-all Domain Detection
We identify whether a domain is a catch-all before verification — so you know what you're working with from the start.
Confidence Levels
Results come with a confidence level: high, medium, or low — so you can set different send thresholds for your campaigns.
Segment by Score
Split your list into tiers — send aggressively to scores above 75, cautiously to 50-74, and skip below 50.
How it works
Get started in minutes. No complex setup required.
Submit an address or list
Send any email address via API or upload a CSV. VeriMails automatically detects catch-all domains during the process.
Receive the scored result
Instead of an 'unknown' status, you get a numeric score and confidence level indicating likely deliverability.
Segment and send smarter
Use the score to segment your sending — maximize reach on high-confidence addresses while protecting sender reputation.
The catch-all scoring changed everything for us. Instead of guessing, we now have real probability data on every catch-all domain. Our deliverability improved 40%.Daniel L. — Head of Outbound at B2B Data Platform, United States
