Synapse Email and Notifications
Synapse creates an email alias for you when you create an account, <your username>@synapse.org. Synapse uses this email as a relay to send and receive messages, keeping your registered email address private.
To send email to <someone>@synapse.org, you must send the email from an address that is registered with Synapse. Messages sent from an unregistered email address will bounce back. Synapse will forward your message to your recipient’s registered email address. When that message is received, your email address will be replaced with your Synapse email alias (<your username>@synapse.org).
Synapse also sends platform notifications via email, such as @mentions in discussion forums, but it only sends them to the single email address you have selected to be your primary email. You can manage this preference on your Settings page. Synapse will also use your primary email to pass on messages sent to your username@synapse.org email address by other users, such as @mentions in discussion forums or direct emails from other users.
