Disposable email database
Is guerrillamail.com a disposable email?
Quick answer
guerrillamail.com is operated by Guerrilla Mail, a disposable / temporary email service. Signups using this domain are almost always throwaway. Block at signup if your product depends on long-term email reachability.
About Guerrilla Mail
Guerrilla Mail is a long-running disposable email provider that issues temporary inboxes which expire after one hour. The service operates a number of alias domains that all forward into the same Guerrilla Mail backend.
Operating since 2006.
What it’s typically used for
Anonymous signups, comment submissions, and any throwaway email registration. Guerrilla Mail addresses are sometimes used to bypass IP-based rate limits on signup forms.
Other domains operated by Guerrilla Mail
The same service runs additional alias domains. Block these alongside the main domain — otherwise users will simply switch to an alias to bypass your filter.
- sharklasers.com
- guerrillamailblock.com
- spam4.me
- grr.la
- pokemail.net
Should you block guerrillamail.com in your signup form?
Block at signup. Guerrilla Mail and its alias domains are pure throwaway providers with no expectation of long-term inbox access.
