Smart send-time optimization

Instead of one blast time for the whole list, smart send-time schedules each contact's message for their modal active hour — the time of day they open, click and browse, derived from their event stream. Contacts without enough signal fall back to a sensible default.

Enabling it

Turn it on per campaign or journey send in the dashboard. AI Studio also proposes it automatically on every draft. There's no separate endpoint — it's a send option applied at schedule time.

How the hour is chosen

The platform reads the contact's recent behavioural events and picks the hour they're most active. The maths is deterministic, so the choice is explainable — no black box.

When to use it

Best for non-urgent marketing (newsletters, nudges) where a few hours' timing shift lifts opens. Skip it for time-critical sends (OTPs, order updates) that must go immediately.
