The Problem Every Agency Knows

You pull 5,000 leads from Apollo, Clay, or LinkedIn Sales Navigator. You run them through your verifier — MillionVerifier, NeverBounce, Bouncer, ZeroBounce. Results come back:

3,500 verified deliverable → into the sequence

500 invalid → removed

1,000 catch-all → ???

That last bucket is the problem. Your verifier flags them "accept-all," "risky," or "unknown" and stops. You have three options, all bad:

Skip them

20% of your deliverable leads gone. Your client paid for those contacts.

Send anyway

Bounce rate spikes, domain reputation drops, deliverability tanks for the rest of the campaign.

Use Scrubby

$0.005-0.008 per email, sends real emails from Gmail accounts, takes 24-72 hours. Another vendor, another cost, another delay.

None of these is a real solution.

What Catch-All Actually Means for Your Campaigns

Catch-all domains accept every address sent to them — real or invented. Your verifier checks if the domain accepts mail, gets a "yes" for everything, and gives up.

But someone like andrew.cooper@company.com is a real person at a real company. The domain is catch-all, but the mailbox exists. Standard verification cannot tell you that. Catch-all resolution can.

30-40% of B2B domains are catch-all. For enterprise-heavy lists — tech companies, financial services, healthcare — it can be 50%+. The bigger your client's target accounts, the more catch-all you hit.

How filtrat.io Solves This for Agencies

Upload your list. Standard verification runs first — deliverable, bounce, catch-all flagged, uncertain. You pay 0.5 credits per confirmed result. Catch-all detection is free.

Then resolve catch-all from the same dashboard. Each address returns confirmed deliverable or confirmed bounce. 3 credits per resolved address. If we cannot determine the result, you pay nothing.

Enterprise domains behind Proofpoint, Mimecast, or Barracuda gateways? filtrat.io detects the gateway and resolves through the real mail provider underneath — standard verification stops at the gate.

From 1,000 catch-all addresses

~600-700 confirmed deliverable → into sequence

~150-200 confirmed bounce → removed

~100-200 unresolved → free, flagged for review

Result: 600-700 leads recovered that your current verifier wrote off.

Pattern Lookup — Know Before You Spend

Before resolving 1,000 catch-all addresses at 3 credits each, check the email format first.

company.com → first.last@ (72%)

Your catch-all list has 200 addresses from company.com. 180 match the first.last@ pattern. 20 do not. Resolve the 180 first — higher probability of real mailboxes, fewer wasted credits.

7 credits per domain lookup. Charged once, covers all addresses from that domain.

What This Means for Your Client Deliverables

Before filtrat.io

"We verified 5,000 leads. 3,500 are deliverable. 1,000 are catch-all — we recommend not sending to those."

After filtrat.io

"We verified 5,000 leads. 4,100 are confirmed deliverable, including 600 we recovered from catch-all domains. 400 confirmed bounce removed. 500 uncertain — not charged."

Same list. 600 more leads delivered. That is a 17% increase in deliverable contacts from the same data your client already paid for.
