I immediately thought maybe I had purchased from this seller before although her member ID or her (gmail) address did not come up in my email searches. I also searched her name. So far nothing has come up for me.Did you look at the seller's ID history? Is it possible you sold to or bought from her in the past and didn't recognize the current ID?
Another possibility is that although it came to your email address, it might have been sent through ebay and anonymized.
For example, I got a question from a buyer and if I look at "her" email address, i.e., if I were going to reply to the email rather than ebay's reply button, the email address would show as:
If her ID is janedoe_0, the email address might be [email protected].
note that this is a made up address ^^^^^ used as an example.
So if I responded, it would go to her email address but I don't know her actual email address.
As far as the email coming from ebay......it was a gmail address. the first part of the address was her full name then @gmail.com.
I will update when she replies to my ebay message. She seems very very eager to sell her bag.
