EmailOnDeck vs Maildrop

EmailOnDeck provides temporary email addresses for sign-ups, confirmations, and privacy protection. A free address typically remains available for hours, often most of the day, but closing the browser or clearing cookies can end access sooner. Free users can send messages only to other EmailOnDeck addresses; Pro users can send anonymous email to anyone. Messages support viewing or downloading attachments. Chrome and Firefox extensions create disposable addresses, and free iPhone and Android apps are available. The browser-based Spy Pixel Scanner says pasted email source stays on the device rather than being uploaded or stored. Pro API access covers address creation and deletion, domain lists, message counts, headers, and raw messages, with a documented limit of 25,000 calls per day; sending through the API is unavailable. API use requires an active Pro account and a 40-character private key. Plans include an ad-supported free option and Pro payments listed at 0.00 BTC or 0.03 ETH, each extending access for 30 days.

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.
