If your campaign is running (sending emails to the prospects that are in it), you can still add steps to it. The prospects in the campaign will receive the new steps if these are added after the latest one they've received.
- If you add a new step on the first position and some prospects already received step 1 and 2 they will not get this new step.
- If you add a new step on the 3rd position, prospects that only received steps 1 and 2 will get this new step. But not the prospects that already received the 4th step.
New steps for prospects no longer in the campaign
If the prospect is no longer in the campaign at the time you add a new step (ex: he received all the steps of the campaign), he will not automatically receive this new step.
However, you can add the prospect again and he will receive the new step as the prospects that you add again in a campaign will not start from step 1 but from where they previously stopped.
