I love that the Cazoomi sync app allows our MailChimp contact lists to stay up to date with the latest contact information in Salesforce. With Cazoomi's automatic syncing and the option to sync on demand, I know that we'll always have the correct contact lists ready to go in MailChimp when I need them.
There was a bit of a learning curve to make sure that I understood all of the sync settings, and my team experienced a few instances where our Salesforce instance and the MailChimp lists did not match up (probably due to user error!). Otherwise, the tool has worked well.
Cazoomi allows my organization to integrate MailChimp with our Salesforce instance automatically, eliminating the need to manually export and import contact lists between Salesforce and our email tool.
