Our verdict on 1SecMail
1SecMail provides disposable email addresses for temporary sign-ups, verification codes, newsletters, forums, and service testing. It is aimed at people who want to receive or send messages without exposing a primary email address. The service supports web access, an Android APK, temporary aliases, inbox history, attachment viewing and downloading, and QR-code inbox access. It also offers custom domains through its paid plans and a developer API service that is still under development.
The Free Plan includes own domains, 3 inbox records, 3 saved messages, and attachment viewing. Standard costs $4.99 per month and raises those limits to 5 own domains, 30 inbox records, and 30 saved messages. Premium costs $9.99 per month with 10 own domains, 50 inbox records, and 50 saved messages. Gold costs $35.99 per year and includes 20 own domains, 500 inbox records, and 500 saved messages. Diamond costs $45.98 per year with unlimited own domains, inbox records, and saved messages. The Pro API Key costs $10 per month and includes private API key access, unlimited requests subject to fair usage, faster response times, and developer instructions with example code.
The main fit is straightforward temporary mail across a browser or Android device, especially when attachment access, aliases, or QR-based inbox access matter. Published product pages describe inbox lifetimes differently, ranging from 60 minutes to a few hours or 24 hours, so users with strict retention requirements should review the current service terms before relying on a particular duration. Inbox protection is listed as none, and the API feature remains under development. Choose 1SecMail for basic disposable inboxes and higher storage limits; choose an alternative if protected inboxes or a fully established API are essential.
