Apollo Case Study: Don’t Skip Catch-Alls, Reveal Them

Header image

Apollo gives you the “skip catch-all” checkbox.
We give you the reason to uncheck it.

The Default Setting Is Costing You Reach

Apollo’s default behaviour treats catch-alls as risky, so by default, they’re skipped. That’s a safe move for new users, but a growth cap for serious senders.

If you always skip catch-alls, you’re getting less reach and lower ROI.

Why “Skip” Isn’t a Strategy

Here’s the data: roughly 40% of any Apollo list are catch-alls.
Around half of them are deliverable.

That’s a 33% boost in usable data hidden behind one setting.

When you skip, you’re throwing away reachable contacts — prospects who could be opening, replying, and converting.

The TLDR Layer: Reveal, Don’t Skip

The fix is simple: don’t replace Apollo — upgrade it.

Export your “risky” results or connect via API.
TLDR Verify processes that catch-all segment through our yes/no engine and splits them into:

✅ Yes — deliverable, send with confidence
❌ No — undeliverable, remove for good

No more “risky leftovers.” Just a clean, expanded, verified list ready to go back into Apollo.

One easy add-on. One more layer of certainty.

Case Example: Apollo → TLDR → Campaign Results

Take a 10K Apollo list.
On average, 4K of those addresses will be catch-alls.
With TLDR Verify’s yes/no engine, around 2K of those could prove deliverable.

That’s 33% more reach unlocked from the same data — and without risking your domain reputation.

Because TLDR Verify maintains a 99.2% delivery rate across 100M+ live sends, you can safely re-engage those contacts while keeping bounce rates <1%.

Don’t Skip Catch-Alls — Verify Them.

Plug TLDR Verify into your Apollo flow and unlock the leads you’re missing.
