Privacy Notice

Last updated: 2026-08-12. This notice explains what MailCheck collects, why, and your rights. It applies to this site while registration is closed and we operate a waitlist only.

Who we are

MailCheck is operated by Ethical AI Syndicate. For privacy questions, contact [email protected].

What we collect

We collect only what you submit to the waitlist form:

• Email address — required, used to contact you about access.
• Name, company, intended use, and monthly volume — optional, used to understand demand and prioritize access.
• Consent timestamp — recorded when you accept this notice and the Terms.
• Technical metadata — IP address and request metadata, processed by our edge provider (Cloudflare) for security and rate limiting.

We do not send marketing email, and we do not purchase or enrich lists. Submitting the form stores your information; it does not subscribe you to any mailing.

Why we collect it (legal basis)

We collect waitlist information on the basis of your consent, which you provide by checking the consent box on the form. You may withdraw consent at any time by emailing [email protected]; we will delete your information unless we must retain it for a lawful reason.

Retention

We retain waitlist information until access launches or you request deletion, after which it is removed. We do not keep it longer than necessary for the purpose collected.

Subprocessors

This site is served behind Cloudflare, which processes request metadata (IP, headers) as described in Cloudflare's privacy policy. We do not share waitlist information with advertisers or sell it.

Verification history & aggregate signal (product data)

When the verification service launches, MailCheck observes and records evidence about email domains and addresses you submit (DNS, SMTP transport, and any outcomes you report). The accumulated, aggregate evidence history is MailCheck's proprietary intellectual property. It is never sold and never shared with third parties, except that appropriately mandated auditors may review it only under a strict non-disclosure agreement and solely to verify MailCheck's own accuracy claims. Your own individual verification records remain yours and are returned to you; MailCheck's IP is the collective, anonymized signal derived across customers, not any single customer's data.

End-result gathering is optional

MailCheck can optionally record what happened after you sent mail (for example a bounce or a reply), via a separately-scoped outcomes endpoint. This gathering is fully opt-in — it requires its own API scope and is off unless you enable it. Reporting outcomes is voluntary and used only to improve the evidence history (e.g. to learn when a "safe to send" result was later followed by a bounce). We do not infer or sell individuals from it.

Your rights (PIPEDA)

Under Canada's Personal Information Protection and Electronic Documents Act, you have the right to access, correct, and withdraw your information. To exercise these rights, contact [email protected].

Changes

We will update this notice if our practices change and revise the date above.
