Stop Treating Every Catch-All Email the Same.

Our Deep Catch-All Checker individually scores every catch-all address, so you know exactly which ones are worth sending to.

Standard email verifiers mark every catch-all address as "unknown" and leave you guessing. MyEmailVerifier's Deep Catch-All Check goes further, using proprietary multi-signal analysis to give each address a real deliverability verdict: High Probability, Low Probability, or Avoid.

The Problem

The Problem With Catch-All Emails

Every email marketer has seen it: you run a bulk verification, and 20–40% of your list comes back labelled "Catch-All". Standard tools hit a catch-all domain and stop. They have no way to tell which addresses are real.

That forces you to choose between two bad options:

🗑️

Discard All Catch-Alls

Lose 20–40% of your entire list. Miss real customers who happen to be on catch-all domains. Leave significant revenue on the table, every single campaign.

💥

Send to All Catch-Alls

Risk hard bounces, damage your sender reputation, trigger spam filters, and get blacklisted by your email service provider, often without warning.

There is a better way: score each one individually.

How It Works

How Deep Catch-All Check Works

Five clear steps from upload to a clean, scored list ready for your next campaign.

Upload Your List

Upload a CSV or TXT file containing your catch-all email addresses (up to 50 MB, one per line). Your credits are reserved upfront, no surprises. Processing begins automatically.

Proprietary Multi-Signal Analysis

Our engine analyses each email address individually using multiple independent signals, not just a single check. The proprietary scoring algorithm builds a confidence score for every address in your list.

Get Scored Results

Every email receives one of three clear, actionable verdicts. No more blanket "unknown" labels. You get precise, individual deliverability scores you can act on immediately.

✅

High Probability

Strong signals indicate a live, active mailbox. Safe to include in your sends.

⚠️

Low Probability

Weak or mixed signals. Proceed with caution or exclude from primary campaigns.

🚫

Avoid

Negative signals detected. Remove from your list immediately to protect your sender reputation.

Download & Send With Confidence

Download your scored results as a CSV. Filter by verdict and send only to addresses that meet your deliverability standards. Every file is export-ready for your CRM or email platform.

Unknown Credits Auto-Refunded

If an address cannot be conclusively scored, it is marked "Unknown" and the credits are automatically returned to your account. You never pay for inconclusive results. Guaranteed.

How does Deep Catch-All Check differ from regular email verification? +

Regular email verification stops when it detects a catch-all domain and returns a generic "catch-all" result.
