Feature-by-feature breakdowns against each service.
Retention and auto-delete, answered
How long do temporary email services keep messages before auto-deleting?
It varies widely. TempMailSpot keeps your inbox alive for 10 minutes by default and lets you extend it in 10-minute steps for as long as you need; when the timer ends, the address and its messages are wiped. Other services range from a fixed 10 minutes to much longer — YOPmail, for example, retains mail far longer but uses public inboxes anyone can read.
What does auto-delete mean for temp mail?
When a temporary address expires, the service deletes the inbox and every message in it automatically — there is no archive or recovery. On TempMailSpot that happens when your countdown reaches zero, which is also the privacy guarantee: nothing is kept after expiry.
What is the difference between TempMailSpot and 10 Minute Mail?
Both give you a free, no-signup inbox that lasts 10 minutes and can be extended. The difference is what you can do with it: TempMailSpot adds domain selection, message export (PDF, EML, JSON, TXT), QR sharing, dark mode, and keyboard shortcuts. The full head-to-head below breaks it down feature by feature.
Which temporary email services can send mail, not just receive?
Most disposable inboxes are receive-only. Guerrilla Mail is the long-standing exception, and TempMailSpot supports outbound mail behind a CAPTCHA so the feature cannot be abused as a spam relay. If you need to reply from a throwaway address, those are the two to look at.
