So i am in process of emailing professors regarding Phd Program in HCI. I was thinking of explaining about my MS thesis , 3 journal publications I had in MS and my research activities during Masters and my resume.

What else should I include in the emails ? What will a Phd Supervisor look for when I am enquiring into the Phd Program? Should i explain how my previous research might align with his current research? Will a reco letter from my current advisor help me out in any way?

Edit 1:Sorry was typing from mobile,might have been some typos.
