About this provider
tempm.com is a throwaway email provider running across 42,300 historical domains. The service generates disposable inboxes on demand, with no registration and a public web interface. It is closely related to the tempmail.lol family in operating pattern, though run under a separate brand.
How it works
Each tracked domain points to a wildcard MX that funnels mail to a single catch-all inbox addressed by username. The service rotates domains as they get filtered by major providers, and exposes a simple HTTP interface for retrieving messages without authentication.
Why block these addresses
Same risks as any disposable provider: inflated bounce rates, dragged sender reputation, and a strong correlation with low-intent or fraudulent signups. tempm.com addresses should be filtered at signup for any platform that depends on long-lived contact with the user.
Catch what historical lists miss
SMTPing offers real-time disposable monitoring, including detection of .edu disposable providers and Gmail, Googlemail, Hotmail, Outlook, Yahoo, Ymail disposable providers. The categories no static blacklist can catch.
