## Overview

BillionVerify is a bulk email verification platform that grew out of the EmailVerify AI product and now runs at the billionverify.com domain. Its core function is straightforward but operationally important: telling you whether an email address can actually receive mail before your campaign sends to it. Rather than relying on format checks, it performs real-time SMTP handshakes that ask the receiving server whether a given mailbox exists.

The service centres on bulk list cleaning, an email validation API, and granular result typing. Every check returns a status such as valid, invalid, catch-all, disposable, role or unknown, and each result category also has its own free single-address checker so you can test the water without buying credits. There is a designated Email Validation API, a WordPress plugin, a white-label option, and an MCP server plus "agent skills" aimed at AI agent workflows.

Beyond verification, BillionVerify bundles a wide set of free diagnostic utilities: SPF, DKIM and DMARC checkers and generators, DNS and MX lookups, blacklist and IP reputation lookups, an email header analyser, a bounce rate calculator and a deliverability test that scores a sent message on authentication, spam filters and placement. Enterprise buyers are served through an FAQ, help centre and documentation, and the platform positions itself as a lower-cost alternative to established verifiers such as NeverBounce, ZeroBounce and Kickbox.

## Pricing & Plans

Freemium. New users get 20 free credits per day, up to 600 a month.

One-time packs, monthly and yearly plans are available; check the pricing page for current rates.
