When configuring your email waterfall, you can select Million Verifier as your validation provider instead of the default ZeroBounce:
1. Click "Add enrichment" and search for "Work Email"
2. Configure your waterfall sequence with your preferred email providers
3. In the validation provider section, change from the default ZeroBounce to Million Verifier
4. Set your catch-all email handling preference
5. Complete setup and run your waterfall
The validation results will appear in hidden columns that you can unhide through the Columns Panel if needed.
