In their own words
1SecMail
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.
SecureTempMail
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.
