temp-mail.org is a disposable email service — it hands out temporary, throwaway inboxes that expire after minutes or hours. People use addresses like anything@temp-mail.org to receive a verification link without revealing a real inbox.
For a product owner, signups from temp-mail.orgare a red flag. These users skip real email verification, can't be reached again, inflate your metrics, and are a common channel for spam, trial abuse, and fake accounts.
