I’ve configured custom transaction emails, and if a customer registers on the site, they do receive the correct (custom) welcome email.
However, if I am in admin and I create a new customer manually (i.e. to enter info for a wholesaler or other special customer), and I check the box to send an email to the customer, then that customer receives the default “Magento Store” email - even though I have created the customer as specifically associated with one of my stores.
As a further bug, that customer ALSO receives a “you have successfully unsubscribed from our newsletter” email immediately after.
I think these are both bugs - but if anyone can shed any light…
