What is Catch-All verification?
When you upload a lead list to standard verification tools, you often find that about 50% of the emails are labeled as Risky, Catch-All, or Unknown. Standard verification can usually confirm about 50% of the list as valid or invalid, leaving a significant portion as "unverifiable."
Catch-All Verification addresses this gap by attempting to verify these email addresses. This process can recover a good number of otherwise "unusable" leads, increasing the number of your potential leads.
Why should you use Catch-All verification?
Catch-All Verification can help you recover 300–400 additional contacts for every 1,000 leads, expanding your pool of potential prospects.
This is especially valuable if:
Your Total Addressable Market (TAM) is small, and you don’t want to miss potential opportunities
You’re running high-volume outreach and want to maximize the number of contacts you can reach
You want to reach prospects who may receive fewer cold emails, making them more likely to engage
