Why disposable detection matters
Throwaway inboxes are the easiest way for low-intent users and bots to get past a signup form. They rarely convert, they skew your activation and retention numbers, and they leave you emailing addresses that will be gone within the hour. Catching them at signup — or cleaning them from an existing list — keeps your metrics honest and your sender reputation healthy.
Frequently asked questions
A disposable or temporary email is a throwaway inbox from a service that lets anyone receive mail for a few minutes without signing up. People use them to bypass signup gates.
Disposable signups inflate your user count, never convert, and can hurt deliverability when you keep emailing dead inboxes. Blocking them keeps your list and metrics clean.
We match the domain against a maintained list of known disposable providers. New domains appear constantly, so the list is updated over time.
