What is a Catch-All Domain?

A catch-all domain (also known as accept-all) is configured to receive emails sent to any address at that domain, even if the specific mailbox doesn't exist. For example, if example.com is a catch-all domain, it will accept emails sent to any@example.com, random123@example.com, or any other address.

Why This Matters

While catch-all domains can be legitimate, they pose a challenge for email marketers because traditional verification cannot determine if a specific mailbox exists. This can lead to:

  • •Higher bounce rates if many addresses don't actually exist
  • •Potential spam traps hidden behind catch-all configurations
  • •Uncertainty about the true deliverability of your emails

How Our Catch-All Detection Works

1

Domain Analysis

We analyze the domain's mail server configuration and response patterns.

2

Pattern Testing

Test with randomized email addresses to identify catch-all behavior.

3

Response Verification

Analyze server responses to determine if all addresses are accepted.

4

Confidence Scoring

Assign a confidence score based on multiple verification factors.
