Hi!
I would like to know if there is a way in which i can automatically tag already existing mailchimp subscribers that come from a specific sign up form on a landing page.
I am hosting a webinar and i am sending my current mialchimp list an email inviting them to register. However, I only want to continue sending e-mails regarding this webinar only to the ones that register. I know Tags are useful for this matter but I am not able to find a way to automatically tag existing subscribers.
I hope someone can help me!
Thank you!
