The Q4 preview laid out the quarter's agenda and promised nothing beyond the shipped list. Three weeks out from quarter close, this mid-check closes that loop: the holiday-run preparation a commerce operator needs is not a future capability list. It is a set of guides and controls already on the announcements hub, each grounded in Q2/Q3 releases that are live today.
The runbooks, already shipped
Three posts carry the peak-preparation content end to end, and each one names only live controls.
- [The holiday-season volume playbook](/blog/holiday-season-volume-playbook-2026). The two levers that decide a Black Friday spike — sender reputation locked in before the spike (10DLC trust score, WhatsApp quality rating, email domain warmup) and the channel fallback matrix locked in during it — plus the pre-season checklist, budget guardrails, and the post-season wrap. Every control it names runs as a tenant-side setting on the platform today.
- [The RCS launch checklist](/blog/rcs-launch-checklist-2026). The five go-live elements for RCS Business Messaging — provider reach, verified agent, approved templates, an SMS fallback, and your consent posture — sequenced operator-style, with the SMS-fallback and cost-model math a holiday sender needs before RCS earns a slot in the mix.
- [Quiet hours and send-time optimization](/blog/sms-send-time-optimization-quiet-hours-2026). The recipient-local-time math behind send windows, including the daylight-saving failure mode that slides a UTC-pinned window into a blocked hour. The policy itself is scriptable:

The operator checklist, revisited
The preview named three controls worth putting on your Q4 checklist; add the runbooks above to it and the list closes.
- Lock sender reputation before the spike. Run the playbook's pre-season checklist now — recheck live 10DLC campaigns, ramp holiday WhatsApp templates at low volume, warm the email domain you will actually send from, and verify CNAM on the phone numbers customers will see.
- Audit send windows in code. Read the quiet-hours policy through the settings API the same way you audit the rest of your configuration; it is tenant-owned and opt-in per channel.
- Cut detokenize loops before peak support volume. The PII vault console groups sealed envelopes by identifier type, so a batch opens in one call — a support-side time-saver when season volume hits.
- Sequence RCS before it joins the mix. If RCS carries holiday traffic, run the launch checklist's five go-live elements and set the SMS fallback posture first.
None of this asserts unreleased capability. The quarterly commitment stands as it did at the preview: the shipped list and the cadence itself, with forward-looking direction clearly labeled there and nowhere else.
