Our wedding will be this coming Sunday, and we recently received a cash gift from my department at work. We will of course send an official handwritten thank you note after the ceremony, but since I am at work today and tomorrow, I thought I might just send the group a quick thank you by email. Or would it be better to wait and send the official note after the ceremony? I'm sure it came out of the department budget rather than a collection, so most people aren't even aware - perhaps just a verbal thank you to my boss the VP/department head?
