Hi,
I’ve been trying to configure this plugin. I’ve got to send Email data on the “Data Sent” window but I can’t connect to Mailchimp:
“The resource submitted could not be validated.”
“[{“field”:”merge_fields”,”message”:”This value should be of type object.”}]”
I’ve tried several possible configurations but always get the same error.

My cf7 is as simple as:
[email* Email]
[submit “Send”]

Mailchimp account is correctly linked and fields are mapped:
Name: email_address , Type: email > {Email}

What am I missing?
