The problem: TTL of 300 seconds. The shared inboxes check fails for cabin rentals.

Every CMS update brings a small chance that shared inboxes breaks. For cabin rentals, we pin versions and test upgrades in a staging copy before touching production.

cabin rentals did not need a portal. They needed a page that said who they are, what they do, and a phone number that somebody picks up before the fifth ring.

We once forgot to renew shared inboxes for a weekend project and it took down a page that cabin rentals linked to from a print flyer. We now set auto-renew on everything.

When we onboard cabin rentals, the first thing we check is shared inboxes. It tells us more about the previous provider than any sales call.

For cabin rentals, the boring path won: HTTPS, a backup that we have restored once on purpose, and a calendar reminder for shared inboxes.

The best shared inboxes setup is the one nobody has to think about. For cabin rentals, that means auto-renew, auto-redirect, and a monitoring ping every four hours.
