Hello,

I’m currently using Invision integrated with Mailchimp, and I would like to clarify how unsubscribe and sync behavior is handled to avoid potential issues with compliance and billing.

Here is my situation:

When a user unsubscribes from emails within Invision, the contact is synced to Mailchimp.

In Mailchimp, I am now archiving unsubscribed contacts to ensure they:

• Do not count toward billing limits

• Do not receive further communications

• Remain suppressed for compliance purposes

My concern is the following:

If a contact is archived in Mailchimp but still exists in Invision (as an unsubscribed user), can ACP re-sync that contact back into Mailchimp as an active or new contact in the future?

This could potentially:

• Re-add archived contacts into Mailchimp

• Increase billing unnecessarily

• Risk sending emails again to users who have already unsubscribed

I want to ensure that:

• Users who unsubscribe remain fully unsubscribed across both systems

• Archived contacts in Mailchimp are not unintentionally reintroduced

• My setup remains compliant and cost-efficient

Thank you in advance for your help.

The software simply adds and removes people to your mailchimp list as subscribed or unsubscribed, and keeps them in sync. I'm not sure what would happen if you archive them in mailchimp, and my suspicion if they are literally removed from the API list, is that it would re-add it.

Essentially, we send them. What it does on mailchimps end when you archive them, would be on mailchimps side. So it may well be a question for them
