Actions in campaigns can be executed at different time.
There are 3 options:
- immediately: action is executed as soon as contacts get to the action
- at a relative time period: is calculated in days. Action is executed in + X days when contacts get to the action. Here you can finely tune when the action trigger with different parameters, see how in this article.
- at a specific date/time: action takes place from this date and time. If contacts get to the campaign after this date and time, action will be executed immediately for them.
