Mail Topology (MVP)

Nova supports two email identity paths.

Identity paths​

  1. Managed Mailbox (Mailcow): Nova provisions assistant inboxes
  2. Google Backup Sender: optional fallback when primary sending fails
  • API and dashboard on app hosts
  • Mailcow on its own persistent server
  • managed Mongo/Redis

Send behavior​

When backup is enabled:

  1. try managed sender first
  2. if it fails, retry with Google backup sender

Important note​

Google backup alias must exist and be verified in Google send-as settings.
