Having dipped a toe into the world of Mailchimp and having the API feeds set up, It's become clear that the customer data coming via the API isn't great.
I'm now £100s into it without even having sent an email yet. It appears that the email data and consents is stored differently on POS and Merchant Tools.
Customers who have consented to marketing on one platform but not the other can cause clashes in the data and whether you can actually sent them an email or not. All the while, the API keeps adding email adresses to my audience figures which costs a fortune for Mailchimp to store.
Sales data is also inconsistant such as last purchase date or last visit making it difficult to make full use of the information.
I think there is a need for some combined platform to manage customer's data which marries up the information coming from both Cloud POS and Merchant Tools, particularly in respect to GDPR consent as I currently am finding it very difficult to manage.
