How to Fix Mailchimp Tagging Issues for WooCommerce Subscriptions

Issue Overview

A WooCommerce store using Mailchimp noticed new customers weren’t receiving the correct tags—especially the “MEMBER” tag used to unlock gated content and trigger welcome emails. One subscription product was especially affected, despite orders being placed successfully.

The tagging issue created downstream problems with:

• Segment-based automations

• Membership access logic

• Visibility of subscriber types in Mailchimp

Diagnosis & Fix

🧩 Check your Mailchimp setup

Make sure the tag (e.g. “MEMBER”) exists in your Mailchimp audience and is tied to an automation or WooCommerce trigger.

🔍 Investigate SKU conditions

In this case, Mailchimp tagging was based on product SKUs. The affected product didn’t have its SKU included in the tag logic—so tags weren’t applied when it was purchased.

🛠️ Update SKU-based logic

Edit your automation workflow or plugin rules to include all relevant SKUs. Save and refresh connections between WooCommerce and Mailchimp.

✅ Run a test

Make a test purchase of the affected product. Check the Mailchimp contact record to ensure both the general tag (“MEMBER”) and product-specific tags (e.g., “INSIDER-MONTHLY”) appear.

🔁 Backfill missed tags

Use filters or exports to identify subscribers who missed the tag. Add tags manually or run a one-time automated update using purchase history.

Final Outcome

After updating the tagging rules, all new subscribers are now correctly tagged—improving automation flow and ensuring members get the right content and access.
