Adding new campaign members to a flow in progress
How do you add new members into an email campaign flow to join existing members who are already mid-flow?
Here's the problem I've run into:
I have an email campaign with 3 emails in the flow separated by "Wait Until this date" steps.
Wait Until Date 1
Send Email #1
Wait Until Date 2
Send Email #2
Wait Until Date 3
Send Email #3
On Date 1, I send Email #1 out to 40 campaign members.
The next day, I have 10 new campaign members that I'd like to include when sending out Email #2 on Date 2.
However, when I click "Run Once" for these 10 new members, they start off by receiving Email #1. This even occurs if I hit "Run Once" after Date 1 has already passed since it's a "Wait Until" command.
In order to circumvent this, I tried removing "Wait Until Date 1" and "Send Email #1" from the flow, after it was sent to the original 40 campaign members. I then clicked "Run Once," and the 10 new members successfully joined in at the step "Wait Until Date 2" since the previous 2 steps were removed. HOWEVER, the original 40 campaign members incorrectly received Send Email #3! This is even with the "Wait Until Date 3" step in place to prevent this from happening.
Marketo clearly does not like its flow to be messed with once running; is there another way to add new members into an email campaign, and have them jump right into the flow at the same step as the existing members?
