Yes, ZeroBounce will still perform email verification. By default, emails that are classified as "catch-all" by ZeroBounce will be returned as valid with "catch-all" as a sub-status. While these are often real emails, there's some uncertainty about whether they belong to the specific individual or if they're aliases.If you want to be more selective, you can enable the "Only Safe To Send" option, which will only return emails that are classified as "valid" and exclude catch-all emails from your valid email list.

You could just use Enrichley native clay integration which does both SMTP verification like zerobounce but also verifies catch-alls in the same validation request so you don’t need to waterfall catch alls and lose credits.
You can use Enrichley's Validate Email action in Clay by following these steps: 1. Access the Enrichley integration in Clay (you can use our Clay-managed account which costs 1 credit per enriched cell).
2. Set up the validation:
• Select your input Enrichley API key (or use Clay-managed account)
• Choose the email column you want to verify
• Optionally, enable auto-update (updates every 24 hours by default)
• Select which validation data you want to add as columnsThe integration will validate both SMTP and catch-all status in a single validation request, returning the email validity status and results.
