# Provider: Email verification

Last updated: 2026-10-10

MillionVerifier checks whether an email address is real by asking the mail
server for its domain directly, live at the moment you run the check.

**What it delivers.** One of six results per address: valid, invalid,
catch-all, disposable, unknown or error. See "[Email quality checks and
verification](https://listplus.ai/en/help/check-and-clean/email-quality-and-bounces)" for what each result means and how it's shown in your list.

**Where in ListPlus.** "Verify Email Deliverability" in the record panel
and in the Enrich menu under Verify.

**Inputs needed.** An email address — nothing else.

**Coverage & freshness.** Checked live against the mail server at the
moment of the check; verifying the same address again within 7 days
reuses that result.

**Credits & charge rule.** Each address costs credits, charged only for a
valid, invalid or disposable result (the price is in "[Price list: what every action costs](https://listplus.ai/en/help/plans-credits-billing/price-list)"). Catch-all, unknown and error results
cost no credits. Addresses the free pre-checks already flag (bad format,
disposable or test domain, role account, typo, numeric-heavy) never reach
MillionVerifier and cost nothing.

**What the provider receives from us.** Only the one email address being
checked — never the rest of your list.

**Company seat, data location, legal basis.** According to its privacy
policy (checked October 2026), MillionVerifier is operated by Southern
Vector Limited, Christchurch, New Zealand. It processes data in New
Zealand, Hungary and other EEA countries, the USA and other countries,
and it names contract performance, legitimate
interests, legal obligations and, where required, consent as its legal
bases.

**Caching.** A result is reused for 7 days if you verify the same address
again — no new check, no credits charged.

## FAQ

### Which service verifies my email addresses?

MillionVerifier. It checks each address live against the mail server for its domain and returns one of six results: valid, invalid, catch-all, disposable, unknown or error.

### What does MillionVerifier receive when I verify an address?

Only that one email address — never the rest of your list or any other column data.

### Is every address actually sent to MillionVerifier?

No. Free local pattern checks catch obvious cases first — bad format, disposable domains, role accounts, test domains — and mark those without ever calling MillionVerifier.

### Does checking the same address twice cost credits again?

No, not within 7 days. A result is reused for a week before ListPlus checks the same address again.

### Where is MillionVerifier based, and what's its legal basis for processing?

According to its privacy policy (checked October 2026), MillionVerifier is operated by Southern Vector Limited, Christchurch, New Zealand, and processes data in New Zealand, Hungary and other EEA countries, the USA and other countries. It names contract performance, legitimate interests, legal obligations and, where required, consent as its legal bases, and may also process data in other countries depending on the service provider involved.

### What's the difference between the free checks and MillionVerifier's check?

The free checks in Analyze only look at the text of the address (format, known disposable domains, role accounts); MillionVerifier is the only check that actually contacts the receiving mail server to confirm the mailbox is real.
