Property management: the crew sees the leak first

The setup

Manager Owen lists rentals@ as the source and adds the office admin plus three techs and the weekend on-call: admin@, felix@, grace@, hugo@ and oncall@.

How the mail flows

1. A tenant reports a burst pipe to rentals@ at 9:12pm.
2. Copes land in all five inboxes within minutes — including the on-call phone.
3. The tech replies from their own address with an ETA; the office sees it in the morning thread.
4. rentals@ holds the timestamped original for deposit and liability disputes.

Why Sinka fits here

• After-hours coverage without giving five people one password.
• Photos of damage arrive full-resolution in every copy.
• Staff turnover is one revoked App Password, not a shared-login reset for everyone.

Watch out for

• Tenants will reply to whoever answered; make sure that thread CCs the office or the record splits.
• Filter noise (rent reminders, newsletters) still copies — keep the source inbox for humans, not bulk senders.
