Pillar 02
Receive Messages Automatically
Learn how MailOnce receives incoming temporary email, updates the inbox in real time, and helps you understand delays or missing messages.
Receiving is a chain: the sender must dispatch the email, the delivery path must reach MailOnce, and the active inbox must surface it. This pillar separates those stages so a slow sender is not confused with an inbox problem.
