Maildrop
Maildrop provides free, temporary email inboxes for receiving messages when you do not want to share a real address.
What Maildrop is
Maildrop provides free, temporary email inboxes for receiving messages when you do not want to share a real address. No signup or password is required, and custom addresses are supported. The service is available on the web and through a GraphQL API that can list mailboxes and messages, delete messages, and automate email testing. Heluna antispam filters process incoming mail; the maker says they reduce spam by more than 90%. Every inbox is public, so anyone can read its messages, and Maildrop cannot send email. Plain-text and HTML messages under 500k are accepted, while attachments are removed. An inbox stores at most 10 messages and inactive inboxes may be cleared after 24 hours or sooner. Greylisting unfamiliar mail servers can delay delivery by at least 15 minutes and sometimes up to an hour. Maildrop logs email and web connections and does not promise complete anonymity.
