FlushMailbox
YOPmail alternative — temp mail without the blocklist
YOPmail is one of the oldest temp mail services — and one of the most blocklisted. When yopmail.com is rejected at registration, FlushMailbox is a free alternative that works on most of the same sign-up flows.

Because YOPmail is so well known, developers add yopmail.com and related domains to disposable-email filters. Streaming services, SaaS trials, gaming accounts, and social apps often refuse YOPmail even though the address is technically valid.
FlushMailbox vs YOPmail
Both give you an instant throwaway inbox with no registration. The difference is acceptance: FlushMailbox uses a mail domain that is not on most public YOPmail-style blocklists, so your address is more likely to pass validation and receive OTP codes.
