Good day Klaviyo People!
We are noticing quite a lot of 400s when doing identify/track calls to Klaviyo. It looks like a lot of email addresses that we get through Shopify can't be processed through Klaviyo. One example is non-ascii email addresses as mentioned in this other post:
But in our system we see it's not limited to non-ascii characters but there are quite a lot of characters that create issues when sending events to Klaviyo.
I looked at the docs but couldn't find anything. Could you provide what is the subset of email addresses that are valid email addresses in Klaviyo? Like a regex you use internally or the set of characters supported?
