Verify before you send

Protect deliverability with recipient intelligence.

Sendzovo combines email verification with actual delivery history so you can catch obvious invalid addresses, flag risky recipients and reduce preventable bounces before they reach your sending IP.

One platform for Verify + Send + Protect.

Verification is not a separate disconnected tool. Sendzovo can use pre-send checks together with real delivery, bounce and complaint signals.

Single verification API

Validate one address from signup, checkout or account flows before you store or send to it.

CSV

Bulk verification

Upload lists, process them asynchronously and export deliverable, risky and invalid segments.

🛡

Verify Before Send

Optionally verify new recipients automatically before a transactional message is queued.

MX

DNS + SMTP intelligence

Syntax, domain, MX, SMTP response, catch-all, disposable and role-address checks.

Recipient Health Score

Blend verification with Sendzovo delivery history, bounces and complaints into one score.

Smart caching

Don't waste credits rechecking recently verified or successfully delivered recipients.

Verification that gets smarter after delivery.

A recent successful Sendzovo delivery can be stronger evidence than repeatedly probing the same mailbox.
