About Maskbox — Temp Mail
Maskbox gives you a disposable email address for signups, so you never have to
hand out your real inbox just to verify an account.
• One tap — generate a throwaway address and copy it into any signup form.
• Catch the code — the verification code or activation link shows up right in
the popup, with one-tap copy. No tab-switching, no inbox digging.
• Live — new mail appears automatically; a badge tells you when something landed
while the popup was closed.
• Private by design — the address is generated in your browser and is the only
key to its mail. No account, no password, no real email required.
• Open the full message in a roomy tab when you want the whole email.
Maskbox is for throwaway signups and one-off verifications — not a replacement
for your primary email.
