Most senders either blast them and burn their domains — or delete them and lose revenue.
There’s a better way.
TLDR Verify gives you a third option: send smart.
The Catch-All Dilemma
“Catch-all” or “risky” emails are the addresses your verifier can’t confirm. The mail server accepts everything, so your tool can’t tell if it’s real or a black hole.
Most verifiers hedge — they flag these as unknown or accept-all and move on.
That means up to 40% of your list sits in limbo.
That’s almost half your potential reach sitting in the “maybe” bucket.
If You Send to Catch-Alls Blindly
Sending blind is the fastest way to wreck deliverability.
Sure, some will land — but enough will bounce to tank your reputation.
Once your bounce rate creeps up, inbox providers start flagging your domains. Warm-up time increases, open rates drop, and your outbound campaigns start dying faster.
Cleaning that list properly gives you a 20% lift in deliverability — and your domains last 3x longer before ESPs start ignoring you.
If You Ditch Catch-Alls Completely
Deleting them feels safe — but it’s costly.
Roughly 40% of any list are catch-alls, and half of those are actually deliverable. That’s 33% more usable addresses you’ve already paid for, just waiting to be unlocked.
The Smarter Third Option
You don’t have to choose between risk and waste.
You can keep the good half and ditch the bad.
That’s what TLDR Verify does.
We take your verifier’s “risky” results — the grey zone everyone else ignores — and run them through our yes/no engine.
The outcome?
✅ Deliverable or ❌ Undeliverable. No in-between.
We’ve proven it across 100M+ live sends with a 99.2% delivery rate.
Stop Deleting Deliverable Leads
Don’t waste the good half of your “risky” list.
Run them through TLDR Verify, keep the usable ones, and send with confidence.
