Maildrop vs SecureTempMail

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.

SecureTempMail provides disposable inboxes for sign-ups, downloads and one-off verifications without requiring an account. Users choose an inbox lifetime from 10 minutes to 24 hours, after which messages are deleted. The receive-only service cannot send email from temporary addresses. It detects verification and login codes for copying, and displays incoming HTML in a sandbox with scripts disabled to neutralize tracking pixels and malicious markup. SecureTempMail says inbound mail uses TLS and opportunistic STARTTLS, and that it does not log IP addresses against inbox activity or build advertising profiles. Its API supports inbox creation, message reading and deletion, and real-time webhooks. The Chrome extension offers per-site aliases, one-click autofill, OTP notifications and a side-panel inbox. Desktop apps are offered for Windows, Apple Silicon Macs and Linux; Intel Macs are not yet supported. The free plan lists unlimited disposable inboxes with up to 24-hour lifetimes and rotating domains, and is ad-supported. Premium costs $39 a year and includes up to 30-day retention, private domains, attachment downloads, no ads, inbox history and search, and priority delivery. The Developer plan costs $190 a year and includes 100k API requests per month, catch-all domains, REST API and webhooks, and an email support SLA.
