Catch-All
StatusIn-appThis domain accepts emails for any address, so the specific mailbox cannot be confirmed.
The company's mail server says "yes" to every address, real or fake. So a normal check can't tell if this person's inbox exists.
Stop Guessing on Catch-All Emails
Catch-All Resolver gives Catch-All and Risky emails a deeper verification, so you keep the addresses that are likely deliverable and drop the ones that aren't.

15 to 30%
of a typical B2B list can sit on catch-all domains, where standard verification can't confirm the mailbox.
27% vs 1%
bounce rate for unresolved catch-all addresses vs verified emails in the same campaign, per industry testing.
Under 2%
is the bounce rate generally considered acceptable. Above that, filtering and throttling get more likely.
Do the math: a 10,000-email list that's 20% catch-all, bouncing at the 27% seen in industry testing, carries about 540 bounces from that slice alone. That's 5.4% of the send.

Stop picking a bad option
Here's what most teams do with these emails today, and what to do instead.
Send them all
Bounces rise, which can hurt sender reputation and inbox placement for every future campaign.
Delete them all
Real contacts at companies with catch-all mail setups get thrown away.
Patch it together
Burner domains, manual checks or a second tool. Slow, costly and hard to scale.

Verify these emails more deeply and keep the ones that are likely deliverable.

A Label Isn't an Answer. Now You Get One.
Most tools stop at flagging catch-all emails or hand you a score to interpret. Catch-All Resolver gives each one a send or remove call.
A label
Tells you the domain accepts everything. Whether to send is still your call.
- No send decision
- Usually sent blind or deleted in bulk
A score
A number you set your own cutoff for, then test and adjust.
- You pick the threshold
- Often an extra add-on or a second tool
A verdict
Each Catch-All and Risky email comes back as likely deliverable or invalid.
- Clear keep or remove call
- Covers Risky results, not just Catch-All
- Runs on results already in Email Verifier
- 2 credits, only on the rows that need it
Keep the Good Ones. Drop the Ones That Bounce.
Turn "we don't know" results into send decisions your sales and marketing teams can act on.
Keep more usable contacts
Save the good emails hidden inside catch-all domains instead of deleting them.
Cut bounces before you send
Flag addresses unlikely to deliver before a campaign goes out.
Make clearer decisions
Get fewer "we don't know" results to argue about with sales or marketing.
Stay in one tool
Run it inside Email Verifier, on the same results and with the same credits.
Built for the Lists Where Catch-Alls Pile Up
Catch-All and Risky results show up wherever B2B email does. Here's where resolving them pays off most.
SDRs, AEs and founders
Cold outbound to bigger accounts
Larger companies often run catch-all mail servers. Delete those contacts and you quietly shrink your best-fit accounts.
Keep the likely deliverable buyers, drop the rest.
Cold email teams
Protecting warmed-up domains
New and secondary sending domains have little reputation to spare. One bounce spike can undo weeks of warmup.
Resolve the risky slice before it goes out.
Email marketers
Campaigns, events and newsletters
Catch-All rows either hold up a send or get removed in bulk, taking real subscribers and registrants with them.
Send to more of your list with fewer surprises.
Agencies and lead gen
Client lists without "unknowns"
Explaining a pile of Catch-All results to a client is hard. So is risking their domain on them.
Hand over a clear keep or remove call.
List buyers
Bought or rented B2B data
Third-party B2B files are often heavy on catch-all domains, which makes their real quality hard to judge.
See which part of the file is likely deliverable.
RevOps and Ops
CRM cleanups and old lists
"Maybe" contacts sit in the CRM for months, excluded from every sequence and never cleaned out.
Turn them into send or remove decisions.
Spend Credits Only Where You Need Answers

Catch-All Resolver FAQ
What is a catch-all email address?
It's an address on a catch-all (also called accept-all) domain. The domain's mail server accepts email for any address, real or made up, so standard verification can't confirm whether a specific mailbox exists.
Why does my verifier say Catch-All or Risky instead of Valid?
Catch-All means the server says "yes" to every address, so a normal check can't tell real from fake. Risky means the server gave mixed or unclear signals, so the email couldn't be verified with enough confidence.
Is it safe to send to catch-all emails?
Sending to unresolved catch-alls is risky. In industry testing, catch-all addresses bounced at 27% versus 1% for verified emails. Catch-All Resolver helps you keep the likely deliverable ones and remove the invalid ones before you send.
What does Catch-All Resolver return?
Each Catch-All or Risky email you run it on comes back as likely deliverable (keep and send) or invalid (remove before sending).
How many credits does it use?
2 credits per email, only on the Catch-All and Risky emails you choose to resolve. Standard verification stays at 1 credit per email. See plans and pricing.
Which statuses can I run it on?
Catch-All and Risky. Valid and Invalid results are already clear. Do Not Send addresses may be real but are unsafe to email, and Invalid Domain addresses can't receive mail, so they aren't part of Catch-All Resolver.
Does Catch-All Resolver guarantee delivery?
No. No verification can guarantee delivery. Catch-All Resolver identifies addresses that are likely deliverable, so you can make a more informed send decision.
