What is the best way to set up this nurture program using nested program/smart campaigns/streams/etc:
Send Email 1
>If click, send Email 1A
>If not, send Email 2
If they clicked in Email 1A, send email 1B
If not, send Email 2
and so on.
Here is an image of the workflow I'm trying to set up within Marketo:
I think you can achieve this using streams and transition rules/smart campaigns.
In your case, you could set it to where a "Yes" takes them to the next stream with the next email you want to send them. And a "No" would keep them in the current stream and they will receive the next email.
To make this possible, you can set up transition rules that trigger off a person clicking a link or visiting a web page.
Stream 1:
Emails 1, 2 and 3
Stream 2:
Emails 1A, 2 and 3
Stream 3:
Email 1B, 2 and 3
and so on.
