What's the best option to integrate the ZOHO CRM with either MailChimp or Campaign Monitor?
I would like to integrate also custom fields to segments or groups of the mailing list.
What kind of data can I push back to the ZOHO CRM? Except the opt-out etc.
I am testing Piesync, Cazoomi and Kloudconnectors. All of them, have limited functionalities in terms of what sending back to the CRM.
