Email Verification API

Verify email deliverability in real time before you send. Now available as two new endpoints:

POST /v1/emails/verify — Single email verification
POST /v1/emails/verify/bulk — Batch verification (up to 1,000 emails per request)

What it does

Real-time SMTP handshake validation
MX record verification
AI-powered catch-all detection
Returns deliverability status, confidence score, risk level, and provider info

Pricing

1 credit per verification. Unknowns (where we cannot determine deliverability) are free.

Why it matters

Bounced emails destroy sender reputation and tank deliverability for your entire domain. Now you can verify before you send — whether that's one prospect or an entire list.
