We recently released a change to the way that Campaigns function, making them open ended. This means that for Campaigns created after this change was made, subscribers will continue through the series when new messages are added to the end of it. This will happen even if the subscriber reached a point that was previously the final action in the Campaign.
This article will review how Campaign messages will send, depending on when the Campaign was created.
After July 15th, 2019
Campaigns created after July 15th, 2019 will be open ended by default. Subscribers will receive all messages in a Campaign, regardless of whether the message was in the Campaign at the time the subscriber began the Campaign.
For example, if a subscriber has received all 3 messages in a Campaign, they will receive the next message you add to the Campaign. This will happen no matter how long you wait before adding that next message to the Campaign.
If, however, you add a message between messages 1 and 2, that newly added message would not be sent to the subscriber because the subscriber passed that section of the Campaign already. The subscriber would not receive any new messages from the Campaign until a message has been added after the messages the subscriber has already received.
Before July 15, 2019
Campaigns created before July 15th, 2019 are not open ended yet. If a subscriber reached the end of a Campaign, they would not receive messages that are later added to the Campaign.
Note: We are in the process of making these older Campaigns open ended as well. Once is complete, when new actions are added to the Campaign, subscribers who had previously ended the Campaign will pick up where they had left off and will continue through the series from the place where they had stopped receiving new messages. There will be a notification added to the Campaigns page when this change is live in your account to make you aware of this update.
