If your email waterfall was unsuccessful, here are some steps to try:
1. Check if you've run out of API credits. If so, purchase additional credits from your email verification provider and then restart the process.
2. Re-run the waterfall for failed attempts by going to your first waterfall column and selecting "Run all rows that haven't run or have errors." This will only process entries that weren't completed previously.
3. Review your input data quality. Make sure you have:
• Company Domain (primary requirement)
• Personal Social Profile URLs (ideally)
• Full Name + Company Name (as fallback)
4. Try adjusting your waterfall configuration by reordering providers or adding different ones to maximize coverage.
5. Consider using individual email finder integrations like Hunter, Datagma, or Icypeas directly if the waterfall approach isn't working.
