Everyone says connect with potential advisors beforehand, but to be honest that sounds so intimidating! Do you have any suggestions on the length of the original email you send out?

Hi there! My name is Andrea Robinson. I'm a senior at Davidson College studying physics. I just wanted to reach out to let you know how appreciative I am of your media presence. Specifically, how you take the time to have a presence online that is very helpful as another WOC in a STEM field. I've recently stumbled across the GEM fellowship and see that you are a fellow. I will definitely be using all of your tips on my application! As someone not much younger than you, it's very encouraging to see you succeed. I'm looking forward to keeping up with your journey and just wanted to say thank you.
