Catch‑All Email Solution
Catch-all emails explained
Common terms include catch-all, accept-all, or risky emails. These email servers accept all incoming emails, even when it doesn't exist, creating verification challenges.
- 40-60% of contact lists contain catch-all emails.
- Higher bounce rates damage your email deliverability.
- Enterprise companies commonly use catch-all configurations.
Automatically classify catch‑all risk and recover valid emails.
Bypass catch‑all. Recover real opportunities.
Classify risky addresses and verify valid inboxes—even behind Secure Email Gateways and catch‑all policies.
- Verify inbox deliverability within catch‑all domains
- Confident classification of risky addresses
- Works with Google Workspace, Office 365, and major SEGs
- Recover 20–30% more usable contacts
What is a catch-all email verifier?
A catch-all email verifier (also written catchall email verifier, or called a catch-all email checker) is a tool that determines which individual addresses on a catch-all — or accept-all — domain actually reach a real inbox. Standard email verification stops at the domain level: it detects that the mail server accepts every address and marks all of those contacts "risky" or "unknown." A catch-all verifier goes one step further and returns a valid-or-invalid answer for each specific address.
That difference matters because roughly 40-60% of B2B email addresses live on catch-all domains. Without a dedicated verifier those contacts are guesswork; with one, Enrichley typically recovers 20-30% more usable emails from the same list at 98% accuracy.
How do you verify a catch-all email?
You verify a catch-all email by resolving the individual mailbox instead of trusting the mail server's answer. A catch-all server says "yes" to every address, so the usual SMTP accept/reject check tells you nothing. Enrichley's proprietary algorithm weighs signals beyond the SMTP handshake — mail-server behavior, address patterns, and out-of-band evidence — and resolves each address to valid or invalid in real time, without ever sending a test email to the recipient.
You can verify a single address, upload a CSV to check a whole list in bulk, or call the API for real-time checks — all on the same credits (1 credit per email). For the step-by-step walkthrough, read How to Verify Catch-All Emails.
When do you need a catch-all email checker?
You need a catch-all email checker whenever your verification tool returns "risky," "unknown," or "accept-all" for addresses you care about. That label is where a standard verifier gives up — and deleting those contacts throws away 40-60% of a typical B2B list, while sending to them blind drives bounces and sender-reputation damage. Verifying them first keeps the valid contacts and drops the dead ones.

Catch-all verification, explained
What is a catch-all (accept-all) email?+
A catch-all — also called accept-all or 'risky' — is a domain configured to accept mail sent to any address, even ones that don't exist. Standard verification can't tell which addresses are real, so most tools simply mark these contacts risky.
How does Enrichley verify catch-all emails — does it send test emails?+
No test emails are sent to the recipient. Enrichley's proprietary algorithm detects the valid inboxes inside catch-all domains in real time without delivering a message — turning contacts other tools discard into verified, reachable prospects while protecting your sender reputation.
How many more emails can I expect to recover?+
Catch-all addresses make up roughly 40-60% of many contact lists. Enrichley typically recovers 20-30% more usable emails by verifying the catch-alls competitors leave marked 'risky'.
Will sending to catch-all addresses hurt my deliverability?+
Sending blindly to catch-alls drives bounces and damages sender reputation. Enrichley verifies them first, so you only send to addresses confirmed valid — keeping bounce rates and reputation in check.
Can I verify catch-alls in bulk and over the API?+
Yes. Verify lists in bulk or in real time through the API, drawing on the same credits as the rest of the platform (1 credit per email).
What's the best email verifier for catch-all addresses in cold email?+
Most cold-email verifiers only flag catch-all (accept-all) domains as 'risky' and leave those contacts unusable. Enrichley is built specifically for catch-all: its proprietary algorithm detects the valid inboxes inside catch-all domains in real time without delivering a message, typically recovering 20-30% more usable emails for cold outreach while protecting your sender reputation.
How accurate is Enrichley's catch-all verification?+
Enrichley verifies catch-all (accept-all) addresses at 98% accuracy, resolving the valid inboxes inside them in real time without sending a test email. That typically recovers 20-30% more usable emails from the 40-60% of B2B lists that are catch-all — the contacts most tools leave marked 'risky'.
