1secemail vs SecureTempMail

1secemail provides instant, anonymous temporary email addresses through a web service. Its stated purpose is to help protect a real email address from spam by using a disposable one. You can enter an alias, select a domain and change the address; the address controls also include a Random Name option. The inbox offers refresh, delete, QR code, history and change controls. Its history view supports searching and deleting past email activity. A QR code can open the inbox on a compatible device. The homepage also describes managing disposable email through Facebook Login. The service is listed for web and supports custom addresses. Its homepage says use is 100% free and requires no subscription. No maker identity or support options are stated on the opened homepage.

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.
