I apologize in advance for waffling on about something (relatively) insignificant-
For professors who have written and submitted LOEs on my behalf- How should I thank them? I feel like emails are a bit impersonal but written correspondence can get tricky finding the correct address to reach them. Also, is it enough just to extend our thanks? Should we also include a token of our gratitude- I was thinking a Starbucks e gift card maybe? And generally what should we say beyond thanks for writing the letter.
Thanks
