Thanks, okiedad.
Here is roughly what I would do...
Coach X (get the name right and don't just say "Coach" with no name),
My name is xxx xxxx and I am a 2021 grad at xx High School. I am a pitcher/first baseman. I play travel ball for xxx.
I am interested in xxxx University (get the school name right; don't say University when it's College, etc.) because of your Biology program (or whatever is generating your interest). I also have done research on your school and your softball program and I like (whatever you like about the school and softball program). I realize you can't contact me directly because of NCAA rules (if this is true), but I have listed contact information for my coaches below and in my attached player profile. I know that you are able to talk to me if I call you on the phone, so please contact my coach(es) if you would like for me to call.
Also, if you have time, my skills video is here (link). I will be sure to send you my tournament schedule each weekend this summer. I have attached my high school schedule, although I understand the chances are low of you making one of my high school games.
Good luck on the rest of your season and I hope you can watch me play this summer.
Thank you,
