My website's members have an Account Page that lets them change their
profile including whether or not they want to be opted-in to my
MailChimp powered newsletter. I am using the MailChimp API (php) to
subscribe or unsubscribe them according to the preference they set.
Both operations appear to be working fine, except I do not get
notified when the listSubscribe() call is made. By 'notified' I mean,
my MailChimp list settings are such that I should be getting emailed
every time someone subscribes or unsubscribes from the list. I DO get
notified via email when listUnsubscribe() is called.
Why am I not getting the email notifications for listSubscribe() calls?
