I’ve never seen this before but over the last 2 days I've gotten over 25 Zapier alert emails that read : “Mailchimp ran into an error: Invalid Resource - (different email address here) has signed up to a lot of lists very recently; we're not allowing more signups for now”.
This is a Zap to add an email address to a Mailchimp list when a customer accesses a thank you page from my Clickfunnels page . It has worked perfectly for years.
Why would so many different spam email addresses be hitting all at once? Can someone tell me what has changed or how I can fix this?
Thanks
