On our latest Q4 landing pages we’re asking to provide just an email address which is being fed into MailChimp. However, like before in Q3, when we get a conversion we also get an integration error:
“MailChimp experienced an error processing your lead: MMERGE1 must be provided - Please enter a value”
No idea where this is coming from. Does any of you know how to solve this problem or what I’m doing wrong?
