Guerrilla Mail

Disposable email: The service provides a disposable email address without requiring registration, and users can also choose their own address.
Spam protection: The maker describes using disposable addresses to keep spam away from a user's real inbox.
Email retention: Incoming email is kept for one hour after delivery to an inbox, or until the user deletes it.
Inbox access: Anyone who knows an Inbox ID may access its inbox; the maker says a scrambled address can provide additional privacy.
Privacy and logs: The maker says it normally keeps logs turned off and may use data from obvious spam for anti-spam, anti-malware, or anti-phishing research.
Encryption: The website can only be accessed using HTTPS encryption.
API: A public JSON API over HTTP is available, and the maker says it may be rate limited without publishing its rate limits.
Email rendering: The API documentation says HTML in email bodies is filtered and images are blocked by default when displayed.
Open source technology: The maker says its email is powered by Go-Guerrilla, an open-source project.
Password manager: The website includes a password manager that generates a different password for each site from a domain and master passphrase, which it says is never stored or transmitted.
Support: The maker asks users to contact it through Facebook or Twitter in English and says it cannot always reply.
Intended use: The maker suggests the service for using an address with parties a user does not trust and for webmasters checking whether their sites send email correctly.
