Mailchimp Intergration query

-- url of the page with the problem -- : shop.conformance.co.uk/
-- HikaShop version -- : 6.1.1
-- Joomla version -- : 5.4.2

I have downloaded and installed the Mailchimp Integration plugin.

All OK and I have set up the integration fine.

I presume what now happens is when someone makes an order their email address is automatically added to my mailing list in Mailchimp.

What I would like to know is, is there a way for users to agree to being added to the mailing list (via a checkbox perhaps) before they are added to the list.

Let me know.

Kind Regards

Duncan
