# HioMail

> HioMail is an independent temporary email service for receiving verification codes, one-time sign-ups and short-lived messages without requiring registration. It lets users switch between a temporary address ending in @gmail.com and available Microsoft Outlook/Hotmail/Live addresses.

HioMail is not affiliated with or endorsed by Google or Microsoft. Message content in both free and long-term mailboxes is automatically deleted after six hours. Free addresses can be recycled after the documented inactivity period; long-term access keeps the address assignment but does not extend message retention.
