Maildrop vs Mailinator

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.

Mailinator provides temporary inboxes and tools for testing email and SMS workflows. Developers, QA teams, and businesses can use it to check delivery for OTP, MFA, onboarding, password recovery, and other email processes at scale. Paid subscriptions include private testing domains, where messages can arrive at any address without creating an inbox first. The REST API retrieves inboxes, messages, and SMS, injects messages, and connects with CI/CD pipelines. Inbound webhooks can accept HTTP POST messages from sources such as alert systems, Zapier, or Twilio, then apply configured rules. SMS can be routed to an inbox or API for automated OTP and 2FA testing. The free public inboxes are readable by anyone, and messages typically auto-delete after several hours. Mailinator is receive-only: it cannot send email or fill out forms. The Public - Free plan is free to use without sign-up. Business costs $79 a month billed yearly; a two-week Business trial is listed. Other plans include Verified Pro at free, Business Plus at $159 a month billed yearly, and Enterprise at a price agreed with the maker with custom pricing.
