Checking to see if this email address is a legitimate email address for Directv: noreply@sat.directv-mail.com

Hi - I received a phone call this afternoon from 480-602-9049. I answered because I thought it was someone else and they said they were from Directv and were trying to get me back as a customer since I've been such a loyal customer in the past. They asked me what services I'm using now and tried to sell me a streaming plan saying I could try it for 2 weeks free of charge! That was a red flag for me as I've never gotten anything free from Directv! Also they were confirming my information and got my email address wrong. It was an email address I've never had. As far as I know, Directv has the correct email address for me. I asked them to send me an email to a different email address that is actually mine so I could review the plan they were trying to sell me and the email came from noreply@sat.directv-mail.com. It doesn't seem legit to me but wanted to confirm. I would actually try the 2 weeks free trial and think about coming back if it is legit! Sadly I don't think it is.
