Hi I am trying to test adding a new subscriber from Bigcommerce (trigger when an order is placed) to Campaign Monitor as a new subscriber. This test has worked fine but when I added a new custom field it returns this error:
Failed to create a subscriber in Campaign Monitor
('Campaign Monitor throttling https://api.createsend.com/api/v3/subscribers/cc165e3b10c549939897f2ab4848cbca.json', 60)
I have tried removing the custom field and this doesn’t help either. Does anyone know how to fix this? All the fields have the correct values in them.
