Receiving Wrong Emails with the “wrong name”

Hi there,
Still new at learning how Magento works.
I have encountered several cases in Magento1 where people are receiving emails with the “wrong name.
There are 2 things I think might be the reason but can’t confirm yet: (a) something weird going on with IDs, e.g. changing email addresses or using $id, or (b) APIs related issue.

For example, the recipients name is Jon, but they receive an email saying “Hi Derek”.

Has anyone encountered similar issuer or know of what I could look at?

any help would be greatly appreciated
