What Maildrop is

Maildrop is a free service for receiving email at temporary, disposable addresses when you do not want to give out your real one, such as for a one-off purchase or website registration. It works on the web without signup or a password, and custom addresses are supported. Developers can use its GraphQL API to view mailbox listings and messages, delete messages, and automate email testing. Incoming messages are filtered with Heluna antispam filters; Maildrop says the filters reduce spam by more than 90%. The service only receives email, and every inbox is public, so other users can read its messages. Plain text and HTML messages under 500k are accepted, but attachments are removed. Inboxes hold no more than 10 messages, and inactive ones may be cleared after 24 hours or sooner to make room. Mail servers it has not seen before may be greylisted, delaying delivery from at least 15 minutes to as long as an hour. Maildrop logs email and web connections and does not promise complete anonymity.
