The reserved timezone property

One property slug is reserved: timezone. Mailcrate reads it itself — a campaign sent at local time schedules each recipient off it. Whichever way it is first written (the contact API, a CSV import column mapped to timezone, or a journey's Update contact step), the definition is created with the Timezone type, and every value is validated as an IANA zone name such as Europe/Amsterdam or America/New_York; anything else is rejected the same way a bad number is on a number property. Creating a property with that slug and another type is refused.

Segments

Group contacts into reusable audiences, either by rules that update themselves or by hand.

Contact Events

Record what people do in your product, see it on each contact's timeline, and use it in segments and journeys.
