Cannot attach formerly deleted email to new customer

Per my earlier question, I have a situation where if I try to create a new customer with an email that was formerly in the system, the customer is added, but the email is not.

This happens both when I add through the API, and done manually through the site.

Concrete example: I used my personal email address for a test customer early into my app development. This test customer has since been deleted, and now when I try to add a new customer (manually on Shopify) who is utilising that email address, the user is created but the email only says “No email provided”.

I need to find a fix for this, as I am migrating to Shopify from another provider, and will be moving over a large amount of customer data. I have to be able to store their email addresses, and not create a ton of lost data as a result of my earlier test customers.

This doesn’t happen for every user, just a couple that I have observed. Is there some sort of script that needs to be run against the actual database to clear any remaining artifacts of my previous testing? Anybody have any ideas on this?

Thanks!

Okay, had some thoughts about this while I was digging in: wondering if these emails may be tangled up because of previous order history. I deleted all the test orders I had in the system, but maybe that’s somehow involved?

Also wondering if TenderTransactions could have something to do with it. There’s no way to delete them from the API, is there a process for having these removed? I entered a few when I was doing initial testing without flagging them as test orders, so I should really have them removed or at least marked as test entries.
