    This failed on the first disposable email address I tried. A Fastmail masked email address.

    You got that. Just not accurate.

    I do wonder why you think disposable email addresses ruin signups. Esp. given they are often used to avoid signups ruining inboxes with spam.

        List? You cannot determine whether an address is temporary from a domain list.

        > a legitimate email address is required.

        i think you need to consider by what measure disposable email addresses are not legitimate.

    I built this because I kept seeing disposable emails quietly ruin signups, waitlists, and metrics — especially on small projects where every user matters. Most solutions felt heavy, paid, or overkill, so I wanted something simple, fast, and free that developers could drop in instantly.

      A throw away mail is a way to anonymously test a service. Maybe you want only people that commit their real identity to evaluating your service, but maybe you will lose some conversion after an anonymous evaluation. You'll also have less word of mouth.

        And nor do you get that with an ostensibly non-disposable address either. Almost anyone can sign-up a regular gmail.com address and then dispose of it.

        You might be right. It's a decision that should be made by the product owners.

          Agreed. Many signups go further and require a "business" address which excludes gmail.com.

        And you'll have a little more bad word of mouth.
