Average Email Validity Rates for India and US Using Apollo, Clay, and Prospeo Data Sources

·Sep 29, 2026 07:22 AM·

What is the email validity % for a 100-email set for India / US geography? Our data sources are Apollo, Clay, Prospeo We do water enrichment via Clay and enrich the email ids if an email is invalid We also do catch-all resolution and even then, for 100 emails, we get 50-60% email ids as valid/emailable in the end.

For India its around 30-45%, and for us its around 50%- 60% using Apollo, Clay, Prospeo; the most annoying thing is paying for invalid data. Maybe check out Dropleads.io , as on export emails are live validated + catchall validation. Saves credits and huge database

Ashwin K. I discovered this video comparing lead gen tools in India (Apollo included). Lusha might be another option to consider for data enrichment. They tackle their data quality in this video and recently announced significant investment in US contacts. That might be one direction where you're addressing both geos.
