Signal 04 The timing

AI Send-Time Optimiser

Every customer gets the message when they are listening

The optimiser learns when each person opens, clicks and buys, and on which channel. It schedules every message for that person's best window, always inside the quiet hours you set.

What it does

Everything inside AI Send-Time Optimiser

Per-person send time

Each contact gets a predicted best hour for each day of the week, refreshed as new opens and clicks arrive.

Channel choice

When a step allows more than one channel, the optimiser picks the one this person engages with most, among channels they opted in to.

Quiet hours first

You set quiet hours per brand and channel. The optimiser never schedules outside them, whatever the model predicts.

Time zones

Times are calculated in each customer's local time zone, useful for brands selling across regions.

Sensible fallback

New contacts with little history get your brand's best-performing hour until their own pattern appears.

Measured lift

A holdout group gets your default time, so you can see the real difference the optimiser makes.

How it learns

Built only from your customer's own behaviour

The model looks at when each person opened, clicked and ordered from your brand on each channel. It does not use bought data, data from other brands or device tracking.

  • Engagement history with your brand only
  • Recent behaviour weighted more than old
  • Explainable: see each contact's best hours
  • Turn off per contact on request
Campaigns and journeys

Works for one-off sends and automated flows

For a campaign, sends spread across a window you choose, such as within 24 hours. For a journey step, the wait ends at the customer's next best moment.

  • Maximum delay you control
  • Flash sales can bypass timing
  • Spreads load on your website and support
  • Works across email, SMS, push and WhatsApp
Questions

About AI Send-Time Optimiser

01How much history does it need?

It starts personalising after a handful of opens or clicks. Until then, it uses your brand's best hour.

02Can I still send at a fixed time?

Yes. Timing is a per-campaign and per-step setting. Turn it off for time-critical messages.

03Does it use data from other brands?

No. Each brand's model uses only that brand's customer engagement.
