Send Windows Map

A thematic guide to how we study when notifications should land—then turn that study into a calendar your team can keep.

Clock face suggesting careful timing

What a send window is

A send window is a stretch of hours when a defined audience is more likely to open and act on a notification. It is not a single magic minute. It is a protected range you schedule into—and a set of hours you deliberately leave alone.

Morning lift

Often strong for transactional confirmations and planning prompts when people first check devices.

Midday trough

Meetings and lunch can flatten opens; useful for low-urgency digests that can wait.

Evening recovery

In Bangkok, early evening dips often recover later—worth measuring before cutting.

How we walk a timing engagement

Every project follows a clear path from inventory to a usable schedule.

1. Stream inventory

List live notification types, channels, owners, and current schedule rules.

2. Clock audit

Confirm which timestamps analytics trust—device, locale, or server—before drawing conclusions.

3. Window discovery

Map opens and same-day actions by hour and cohort; mark holidays separately.

4. Quiet-hour policy

Define silence and the few alert classes allowed to break it.

5. Cadence check

If frequency is the question, design a fair experiment rather than stacking more sends.
