Mailchimp: "Existing Members" Data only for Lists with Campaings?


I'm trying to retrieve Subscribers Data from the past for all my lists. But for some reason, Mailchimp only returns data when the metric "Existing Members" for those lists which had been actively used in the past.  "Member Count" only for works for today's current data. 

Is there a way to get the past subscriber data even if no campaign was ever sent?



  • Hi Wanja,

    The metrics for that setup with the list growth history are known to be bugged in the MailChimp API and won't work right:
    MailChimp Known Issue: List Growth History Returns 0 For Some Months

    ​So that may be why you're not getting data for unused lists. Sadly, as the bug is within their API, there's not much we can do about it. You may want to reach out to MailChimp for further support/complaint.
