I feel like I'm going mad? I'm certain that I used to be able to add people to a mailing list using the MailChimp Activity extension. It appears in the right-hand sidebar and there is a link that says 'View subscriptions'. I could then check a box to add them to one of my mailing lists.
Something changed. I can still see the 'View subscriptions' link, but only for people who I've already added to MailChimp. For other users, I now see the message
'There is no record of the email address "firstname.lastname@example.org" in your account' - and no link to add them via 'View subscriptions'.
Am I wrong? Zendesk support insist that I couldn't do this, but I have had a workflow set up for the past two years - users give permission to add them to our Mailing list when they create a ticket, and if I see that they've checked that box when I answer their ticket then I add them to a mailing list.
It's definitely changed, and I don't know why?!
