Disposable email addresses: what disposable: true means

valid disposable: true

The address belongs to a known temporary (disposable) email service.

What it means

Disposable email services create inboxes that work for minutes or days, with no sign-up. People use them to get a download or a trial without giving their real address.

The mailbox may exist right now, so the result can be valid, but safe_to_send is false: the inbox will soon disappear, nobody reads it after that, and it will not become a customer you can reach.

Why it happens

• Sign-ups for free content, trials or coupons by people who do not want follow-up emails.
• Fake accounts created in bulk.

What to do

• Block disposable addresses in signup forms when the account or trial has value, and ask for a permanent address.
• Remove them from marketing lists.
