Detect domains that accept all emails regardless of the mailbox existence. Make informed decisions about your email campaigns with accurate catch-all detection.
Identify domains that accept all email addresses, even non-existent ones
What you get with our verification:
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.
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:
We analyze the domain's mail server configuration and response patterns.
Test with randomized email addresses to identify catch-all behavior.
Analyze server responses to determine if all addresses are accepted.
Assign a confidence score based on multiple verification factors.
Identify high-risk domains and adjust your email strategy accordingly.
Make informed decisions about which emails to send for optimal inbox placement.
Avoid sending to potentially non-existent addresses that could harm your sender score.
Segment your lists based on domain types and optimize campaign performance.
Prioritize outreach to verified individual mailboxes over catch-all domains.
Prevent abuse and maintain platform quality by detecting catch-all signups.
Ensure compliance and data quality in large-scale email operations.
