I am using Mailchimp for my newsletters.
I could not find online info useful to implement point b) of the following steps :
a) When a contact is inserted in my list "new contact", the series of newsletter "new contact" starts
b) when a contacts performs a certain action (clicking on a link inserted in one of the newsletters) he should be moved to another segment which will trigger a new series of newsletter (newsletter "user clicked on link a").
Can you help in suggesting how I could achieve point b) with mailchimp or other apps?
