Guerrilla Mail Not Working? Here's What to Do
When Guerrilla Mail goes completely down, users are left without their temporary inbox and any pending verification emails. Here is how to check the...
Common Issues
- Complete site outages where guerrillamail.com returns a connection timeout, blank page, or HTTP error code. These outages can last from minutes to hours and typically affect all Guerrilla Mail domains simultaneously since they share backend infrastructure. During complete outages, both the web interface and email receiving servers go offline.
- Partial outages where the web interface loads and appears functional but email delivery stops working behind the scenes. You can see your inbox and any previously received emails, but no new emails arrive, even from senders you know have sent messages. These partial outages are particularly frustrating because the service appears to be working normally.
- DNS resolution failures for guerrillamail.com in certain geographic regions or on certain ISPs. Some ISPs cache DNS records aggressively, and if Guerrilla Mail changes their server infrastructure or IP addresses, users in affected regions cannot reach the site until the cached DNS records expire, which can take hours.
- The Guerrilla Mail API going down independently of the website, or vice versa. Developers and QA teams relying on the API (api.guerrillamail.com) for automated tests may find it returning errors or timeouts even when the website appears fully functional, because the API and web interface can run on different infrastructure.
- SSL certificate expiration or renewal issues that cause browsers to display full-page security warnings, effectively blocking access to the site for non-technical users. When certificates lapse, most modern browsers refuse to load the page without an explicit security override that many users do not know how to perform.
- Email loss during outages. Guerrilla Mail does not appear to queue emails during downtime for later delivery. Any verification emails or messages sent to your address while the service is down are likely dropped permanently and cannot be recovered after the service comes back online.
Troubleshooting Steps
Try accessing guerrillamail.com from a different network (switch from WiFi to mobile data, or use a VPN). If it loads on another network, your ISP may be blocking or having routing issues to Guerrilla Mail servers. Try flushing your DNS cache (on macOS: sudo dscacheutil -flushcache, on Windows: ipconfig /flushdns).
Search Twitter or Reddit for "guerrilla mail down" with a recent time filter. DownDetector also tracks Guerrilla Mail outage reports. If many others are reporting issues, it is a confirmed outage and you need to wait or switch services.
Guerrilla Mail runs several mirror domains. Try guerrillamail.info, guerrillamail.net, or guerrillamail.de. These sometimes run on different servers and may be available when the main .com domain is down.
If you need a working temporary email right now and Guerrilla Mail is down, NukeMail provides instant inbox creation with no signup required. Visit nukemail.app, pick a name, and your inbox is live in seconds. You get 24 hours of active access and can return using your access code.
Unfortunately, if Guerrilla Mail goes down while you have an active inbox, any emails that arrive during the outage are likely lost. Guerrilla Mail does not queue emails during downtime. You will need to request new verification emails from whatever services you were signing up for, using a new address on a working service.
Why Consider Switching
NukeMail runs on dedicated infrastructure with monitoring and high availability practices. The service is designed to handle traffic spikes and infrastructure issues gracefully — emails are received and stored reliably rather than being silently dropped during periods of instability.
With NukeMail, your access code means you are not locked to a single browser tab or session. Even if you need to switch devices, change browsers, or recover from a crash during an unexpected situation, you can resume your inbox anywhere by entering your access code.
NukeMail provides 24 hours of guaranteed active access for each inbox, compared to Guerrilla Mail's approximately 1-hour window that can be interrupted by service instability. The longer window means delayed verification emails have ample time to arrive even during slow periods.
NukeMail uses fresh, regularly rotated domains that are not associated with nearly two decades of disposable email history. Guerrilla Mail's long-established domains are on virtually every blocklist, while NukeMail's domains look like normal email to both automated systems and human reviewers.
