About
uChecker is an online email verification service for validating individual addresses and cleaning bulk lists through syntax checks, DNS and MX lookup, and SMTP mailbox verification. It supports uploads in .txt and .csv formats, processes jobs up to 9 million addresses, and returns results as Good, Bad, Risk, and Unknown lists with detailed rejection reasons.
The service is available through a web dashboard, REST API, and Telegram bot. The pricing page shows a free allowance of up to 100 addresses, then paid volume pricing that drops from 0.20 ₽ per address on smaller plans to 0.05 ₽ per address at 500,000 addresses and above.

Free Tier Value
This free tier gives a real but tightly capped monthly allowance: up to 100 email validations with no credit card required. The cheapest paid option is 1,000 addresses for about $2.56/month equivalent, so the free tier is worth roughly 40% of that starter plan’s value, or about $1/month.
What's included in the free tier
- Free validation of up to 100 email addresses per account.
- No credit card required for the free tier.
- Access to the email verification service for a test sample from your own list.
