Decent but room for improvement

Thank you for taking the time to leave this detailed review @acal. I’m glad to hear that you’ve managed to make this work for your needs within the plugin’s capabilities.

We do have plans to integrate with tags in a future release (no ETA) and our development discussion can be followed here – https://github.com/strangerstudios/pmpro-mailchimp/issues/110

For now we recommend using Segments in Mailchimp that are dynamically updated based on merge fields for list subscribers.

Going this route, you will maintain (and pay for) a single list in your Mailchimp account. You can assign all members to the same list. Then, create a segment for each “group” that automatically updates based on the merge field for their level ID.

See this guide for detailed information:?https://www.paidmembershipspro.com/create-segment-mailchimp-specific-membership-level/

I’m not sure why it would try to run this code on log in as that’s not default behavior, our support team would be more than happy to help troubleshoot this further if you’d need . If you run custom code to give a non-member a level during the log in process this may interfere – this is all I can think of that may be causing this.

I hope this helps. All the best with your membership journey.
