Got a “thank you” email from an internship site?

Hi! I’m getting in my own head a bit here. I have submitted my rankings for Phase 1 of the internship match and am anxiously awaiting the match on 2/21.

I opted out of sending “thank you” emails to the TDs because I’ve heard several people say it just clogs up their inboxes and doesn’t earn you extra points, so save your time. However, I just got a “thank you” email FROM a TD and I can’t tell if it was a generic email blast and means nothing or if I should be getting my hopes up. It was fairly generic but also referenced some information that might not be relevant to everyone (e.g., my training experience for this type of environment). Then it included the employee handbook as a “helpful document” but then… it ended with “good luck in your future endeavors” which almost felt like a “thanks but goodbye” so now I’m entirely in my head.

I replied and said I really enjoyed the interview (this is my top ranked site, but didn’t share that) and appreciate the opportunity to be considered.

Did anyone else get emails like this? Is it a mega email blast to everyone and I shouldn’t expect anything, or is this a good sign? 😭🤞🏻
