Everything you need to know about bulk email verification with DNSai Email Verify.
DNSai Email Verify is a bulk email verification platform that checks whether email addresses are valid, active, and safe to send to. It uses DNS lookups, SMTP mailbox probing, and AI-powered analysis to deliver accurate results.
Our multi-layered engine achieves high accuracy by combining syntax checks, DNS/MX validation, SMTP probing, and AI analysis. Each result includes a confidence score (0–100) so you can make informed decisions about each email.
No. Our SMTP probing checks if a mailbox exists by initiating an SMTP handshake but does not actually deliver any email. The recipient will not receive any message or notification.
You have two options:
The system automatically parses, deduplicates, and validates the format before processing.
We accept .csv and .txt files. For CSV files, emails should be in the first column (a header row is fine). For TXT files, place one email address per line.
No. The Free plan gives you 100 email verifications per month at no cost and no credit card required. You can upgrade to a paid plan anytime if you need more.
Each email verification uses 1 credit. Your monthly credit allowance depends on your plan:
Credits reset automatically each billing period. See our pricing page for full details.
No. Credits reset at the start of each billing period. We recommend choosing a plan that matches your typical monthly usage.
Yes. You can change your plan at any time from your account page. Upgrades take effect immediately with the new credit allowance. Downgrades take effect at the start of your next billing period.
