Why signups from minuteinbox.com cost you money
People reach for minuteinbox.com when a form asks for an email they do not want to give: to grab a free trial, a discount code or a download. The account looks real in your database, but the welcome email, onboarding sequence and receipt all go to an inbox nobody reads again.
The damage is quiet: inflated signup numbers, trial-to-paid rates that look worse than they are, bounces that hurt your sender reputation, and in the worst case one person farming endless trials with a fresh minuteinbox.com address each time.
How to block minuteinbox.com on your signup form
The quick fix is a domain check before the account is created. Our free list of disposable email domains includes minuteinbox.com and is public domain (CC0):
const res = await fetch('https://usevetto.com/disposable-domains.json');
const throwaway = new Set(await res.json());
function isThrowaway(email) {
const domain = email.split('@').pop().toLowerCase();
return throwaway.has(domain); // true for 'minuteinbox.com'
}A static list goes stale within weeks, because new throwaway domains appear daily. Vetto keeps the list current, also checks the domain's mail servers live, and shows the visitor a friendly message instead of a dead end.

Frequently asked questions
Is minuteinbox.com a temporary email service?
Yes. minuteinbox.com is on Vetto's list of disposable email domains: anyone can receive mail there without an account, and the inbox is usually public or deleted after a short time. Treat signups from it as throwaway.
Should I block minuteinbox.com on my signup form?
For a free trial or a freemium product, yes: people use minuteinbox.com to grab a trial without giving a reachable address, so the account never activates or pays. Show a friendly message asking for a real address instead of a silent error.
Can minuteinbox.com receive email?
Yes, it publishes MX records (mail.minuteinbox.com), which is exactly why it works as a throwaway: the code arrives, the person copies it and never comes back.
