About MailGenie

MailGenie is a temporary email service that has operated 1 disposable domains since we first observed the service on 2026-04-12. Users typically generate throwaway email addresses on MailGenie to sign up for sites without exposing their real inbox; addresses expire automatically after a short window, with no long-term association between the address and its user. The service offers no account creation, no password, and no recovery — anyone who knows an address can read its inbox until the messages roll off. That convenience is exactly what makes MailGenie attractive to both privacy-conscious users and to anyone running automated signups at scale.

Why people use MailGenie

Legitimate use cases

Privacy-conscious users rely on MailGenie when they want to interact with an unfamiliar service without exposing their primary inbox. Common scenarios include downloading a whitepaper or e-book that requires an email address, trying a SaaS free trial before committing, signing up for a one-time event or webinar, or evaluating a product before deciding whether to share real contact details. For these low-stakes use cases, MailGenie provides a clean buffer between the user and the service. Journalists, researchers, and security professionals also use temporary inboxes when testing how a third-party service handles signups, to avoid contaminating their permanent address book with marketing lists or, in the worst case, with mail from a service that has been breached.

Abuse patterns

Bad actors exploit MailGenie to create fake accounts at industrial scale. Typical abuse patterns include fraudulent free-trial farming where multiple accounts are created to reset a trial counter, abusing referral or sign-up bonus programs, bypassing one-account-per-user rate limits on marketplaces, creating synthetic identities for click fraud, and registering throwaway credentials for credential-stuffing attacks on other platforms. Because MailGenie domains are publicly known and require no identity verification, they are a first-choice tool for automated account creation. The economic effect on a SaaS business is real: inflated signup metrics that mislead growth planning, support costs spent triaging fake accounts, increased risk of credential abuse on subsequent product surfaces, and contaminated retention cohorts where the denominator includes accounts that were never going to be real users in the first place.

How to block MailGenie signups

Three approaches, ordered by accuracy:

Manual regex (least reliable)

const BLOCK = /@(mailgenie\.[a-z]{2,4}|mailgenie\.com)$/i;
if (BLOCK.test(email)) reject();

Frequently asked questions

Is MailGenie safe to use?

MailGenie is operated by anonymous third parties and offers no privacy guarantees. Anyone who knows the address can read incoming mail — there is no password or access control on the inbox. Sensitive data sent to a MailGenie address, such as password reset links, financial documents, or personal identification, is effectively public. Do not use MailGenie addresses for password resets, account recovery, two-factor authentication codes, or any communication you expect to remain private. From an operator's perspective, allowing MailGenie addresses for high-value flows like account recovery or invoicing is itself a security risk — an attacker who guesses or pre-claims an address can intercept any messages sent to it.

Can I receive emails on MailGenie?

Yes — MailGenie addresses receive incoming email and display it in a public or pseudo-private inbox until the address expires or is recycled. The inbox is typically accessible to anyone who types in the address, which means it offers no real privacy. Some MailGenie domains also accept email for any subdomain or random string, making it easy to generate effectively unlimited distinct addresses on demand. This catch-all behavior is one of the strongest signals we use to classify MailGenie as disposable: a single MX record accepting mail for thousands of distinct local parts on hundreds of distinct domains is not how legitimate inboxes work.

Is using MailGenie legal?

Using a temporary email service like MailGenie is legal in most jurisdictions. However, individual sites' terms of service often explicitly prohibit disposable addresses, and using one to bypass paid-account limits, circumvent fraud controls, or inflate signup metrics can breach those terms and, in some jurisdictions, constitute fraud or computer misuse. For ordinary privacy use cases — such as downloading content anonymously — MailGenie usage is generally permissible. For product operators on the receiving end, declining to accept addresses from MailGenie is similarly legal and well-supported by industry practice: every major SaaS company maintains some form of disposable-domain block list, either internally or through a third-party API like EmailProbe.

How does EmailProbe detect MailGenie emails?

EmailProbe matches addresses against 1 known MailGenie domains plus the service's mail-server infrastructure. Detection happens at the edge in under 50ms.

Can I block all MailGenie domains at once?

Yes — every MailGenie domain is flagged as disposable by the EmailProbe API. A single integration blocks every current and future MailGenie domain without a manual list.

How long do MailGenie email addresses stay active?

Address lifetime on MailGenie varies — some addresses are intentionally short-lived (a few minutes to an hour) while others persist as long as the user keeps the browser session open. After the retention window, incoming mail is silently discarded. For a SaaS operator, the practical implication is that any automated follow-up email (a day-2 onboarding nudge, a billing notice, a security alert) is likely to land in an inbox that no human will ever check.

Can users still verify their email if they signed up with MailGenie?

Most MailGenie domains do receive verification emails — that's the entire point of using one — so a plain double opt-in will not filter them out. Effective filtering requires checking the domain against a known disposable list before the verification email is sent, ideally during the signup form submission itself. EmailProbe's free API call returns a verdict in under 50ms, which is fast enough to gate signup without harming the user experience for legitimate addresses.

Why do new MailGenie domains keep appearing?

Disposable services rotate domains continuously to evade simple block lists. MailGenie alone operates 1 domains today, and that number grows weekly as new domains are registered or repurposed. Maintaining a static text-file blocklist means you ship code every time a new domain appears; using an API like EmailProbe means new MailGenie domains are flagged automatically without any change on your side.
