Cannot import WooCommerce customers into Zoho Campaigns

Cannot import WooCommerce customers into Zoho Campaigns

Hello,

We are trying to set up an automated email sequence that will go out to our WooCommerce store customers. I can't get the complete list of customers to sync with Zoho Campaigns though. It syncs completely with our Mailchimp account but not with Zoho.

Is there a setting that I am missing? Thanks in advance!
