Catch-All Email Checker
The catch-all email checker from Truelist lets you instantly detect whether a domain is configured as catch-all (also called accept-all). Enter any email address and find out if the domain accepts every message regardless of whether the mailbox exists — a key signal for email deliverability and list quality.
Try it out.
Why check for catch-all domains?
Catch-all domains silently accept every email sent to them — making it impossible to tell if a specific mailbox actually exists. This tool helps you identify those domains so you can make smarter decisions about your list quality and deliverability.
- Identify Risky Addresses
- Catch-all domains accept emails to non-existent mailboxes, which can inflate your apparent deliverability while hiding real problems.
- Improve List Quality
- Knowing which addresses are on catch-all domains lets you flag or segment them separately, keeping your engagement metrics accurate.
- Protect Sender Reputation
- Sending to catch-all domains can lead to delayed bounces or spam trap hits. Identifying them early protects your sending score.
- Qualify Prospects Accurately
- For sales and outreach teams, knowing if a domain is catch-all helps you prioritize contacts where you can actually confirm mailbox delivery.

Frequently asked questions
Can't find the answer you're looking for? Reach out to our customer support team.
- What is a catch-all email domain?
- A catch-all domain (also called accept-all) is configured to accept every email sent to it, regardless of whether the specific mailbox exists. This means verification checks can't confirm individual mailbox existence.
- Why are catch-all domains risky for email marketing?
- Because emails appear to deliver successfully, but may be silently discarded or unmonitored. Over time this can lead to poor engagement, delayed bounces, and potential spam trap exposure.
- Is this tool free to use?
- Yes — this catch-all checker is 100% free with no account required.
- Can I check catch-all status in bulk?
- This tool is for one-off lookups. Truelist's paid plans support bulk list verification with catch-all detection across your entire email list.
