Filter Unreliable Catch-All Domains

Catch-all domains accept any email without validation - your message disappears into a void. Notis automatically identifies these problematic domains, so you know which companies won't respond reliably.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Catch-All Verify

Tool to check if an email domain is catch-all. Use after confirming email validity.

Why this helps

Sending to catch-all domains wastes effort because emails are accepted but rarely delivered to real people, tanking your open rates

  • Automatically identify domains that catch all emails without validation
  • Skip unreliable outreach targets and focus on companies with real email systems
  • Improve campaign success rate by targeting only quality domains

Setup

Build it in a few focused steps.

  • 1Connect Clearout to Notis
  • 2Create automation: 'When a domain is mentioned or a prospect company is shared, check if that domain is catch-all'
  • 3Choose your trigger - mentions in Slack, email forwards, or CRM webhook
  • 4Notis confirms it will check the domain against Clearout's catch-all database
  • 5Test with a known catch-all domain (optional) or proceed - Notis will check automatically

Questions about this workflow

What's a catch-all domain?

A catch-all domain accepts emails sent to any address @domain.com without validating whether that address exists. Your email gets accepted but often never reaches a real person.

Should I completely skip catch-all domains?

Not necessarily - some are legitimate. But they have lower deliverability. Notis flags them so you can decide whether to outreach or skip.
