Frequently Asked Questions

Got questions? We've got answers. Explore how our verifier works behind the scenes.

What is a Catch-All (Accept-All) domain?

A catch-all mail server is configured to accept all incoming messages, even if the user mailbox does not exist on the domain. Because the server always responds with a "250 OK" handshake, standard validation tools cannot detect if a specific address is active, which frequently results in campaign bounces if unchecked.

How does the AI Catch-All Finder achieve 99% accuracy?

Instead of relying on basic guess methods or outdated databases, our engine utilizes multi-layered validation pathways to check corporate server configurations in real time. We determine if the target mailbox is active and routing correctly, finding the exact deliverable path without sending emails.

Why are pre-checks free?

Pre-checks verify if a target domain is compatible with our real-time verification process. We offer this tool for free to help you optimize your outreach budget. You check the domain verifiability status first, ensuring you only spend credits on solvable leads.

How does the credit billing model work?

We charge credits dynamically: Free Domain Pre-checks cost 0 credits. Checked domains that are resolved as Invalid or Unverifiable cost 1 credit (for the lookup). Checks that successfully verify and extract a valid email address cost 3 credits.
