1SecMail vs Maildrop

1SecMail provides temporary disposable email for sign-ups, with mailbox creation that does not require registration or personal information. Users can send and receive messages, create custom aliases, and receive attachments to download before they expire. Its guide says addresses and related communications are usually erased automatically after 24 hours. The service is available on web and Android, and a Chrome extension provides access to temporary email. Developers can use published API documentation covering domains, mailbox creation and management, message retrieval, and attachment downloads; however, the API-key feature is currently under development. Premium offerings list additional domains, inbox records, saved messages, attachment viewing, and support. The Premium page also advertises 100MB storage and no ads. A free plan is available; Standard costs $4.99 a month, and paid plans start at $4.99 a month. 1SecMail cautions that public temporary addresses are not suitable for sensitive or financial information.

Maildrop provides temporary disposable email inboxes for receiving messages without sharing a real address. It requires no signup or password and supports custom addresses, making it suitable for one-off purchases and website registrations. Developers can use a GraphQL API to retrieve mailbox listings and messages, delete messages, and automate email testing. Incoming mail passes through Heluna antispam filters, which Maildrop says reduce spam by more than 90%. Every inbox is public, so other users can read its messages, and Maildrop cannot send email. Plain-text and HTML messages under 500k are accepted; attachments are removed. An inbox holds at most 10 messages, and inactive inboxes may be cleared after 24 hours or sooner. Mail servers not previously seen may be greylisted, delaying delivery by at least 15 minutes and sometimes up to an hour. Maildrop says it logs email and web connections and does not promise complete anonymity. The service is free and available through its web interface and API.
