Email Verification API
Catch fake, disposable and undeliverable emails at sign-up.
What the Email Verification API does
The Email Verification API checks an address without sending it anything: whether the format is valid, whether the domain accepts mail (MX record), whether it is a throwaway or disposable address (about 9,800 known domains), a free provider like Gmail, or a role address like info@ or sales@.
Popular use cases
- →Block disposable emails at sign-up and on free trials
- →Clean lead lists before email campaigns
- →Flag role and free-provider addresses for B2B lead scoring

Frequently asked questions
Does the email API send a message to the address?
No. It checks syntax and the domain’s mail records only, so the person is never contacted.
How much does the Email Verification API cost?
The Email Verification API on API Sathi starts at ₹0.50 per successful call plus 18% GST, paid from a prepaid wallet. There is no monthly fee or minimum volume, and recharges of ₹1,000 or more earn bonus credit. Live prices for every API are on the pricing page.
Can I test the Email Verification API for free?
Yes. Every account gets a TEST key that calls the Email Verification API in the sandbox at no cost and returns realistic sample responses, so you can finish your integration before adding money to the wallet.
Am I charged if a Email Verification API call fails?
No. You pay only for successful calls. If the source is unavailable, times out or rejects the request, the amount held for that call is released straight back to your wallet.
