Caveats and limits

Mailchimp is available in beta. Treat the first sync as a controlled rollout, not a bulk marketing migration.

Important limits

• Your shop must be included in the Mailchimp beta rollout before setup.
• TracsConnect syncs TRACS customers into one selected Mailchimp audience per shop connection.
• TracsConnect does not create the Mailchimp audience for you.
• New contacts default to Pending opt-in unless you choose Subscribed.
• Choose Subscribed only when your shop has confirmed the customer can receive marketing email.
• TracsConnect does not re-add contacts Mailchimp has marked unsubscribed or cleaned.
• Automatic sync should stay off until a preview and a live run look right.
• A large first sync may queue work in batches instead of finishing immediately.
• Disconnecting Mailchimp stops future sync work, but it does not delete contacts already in Mailchimp.

Rollout advice

1. Start with a small sync limit.
2. Review Preview counts with your rollout contact.
3. Keep Automatic sync off for the first live run.
4. Check the Mailchimp audience after the first live run.
5. Turn on Automatic sync only after the shop trusts the results.
