E-mail Apple Gift Card - is it a scam?

I bought an iPhone 12 mini a few weeks ago. I traded in an iPhone 6 and received an email a few days ago saying it’s complete and they would credit my account or original form of purchase $35.00. I’m telling you this backstory because today I received three separate emails talking a purchase I made for an Apple Gift card in the amount of 39.55. It says I purchased it and sent it to myself. Some of the sentence structure is not familiar for Apple sites. I did look at my own purchase history on my Apple account and don’t see any purchases in this amount. Is it a scam? I don’t know why I would get 3 emails either. I was given an Apple Card for Christmas which I used, in part to pay for my new 12 mini. Any help would be appreciated.
