Boy i hear ya. I just got a thank you card from a wedding 4 months ago. I didnt go to the wedding, i just sent the gift from ordering it online, so its nice to know they did actually get it. I never did get a thankyou from a baby shower last year - i think maybe they emailed it, cuz they called asking for my email, but then their call broke my phone so i had to get it reset and then google didnt believe i was me(!), so i had to get a new email! Lesson being, people should not depend on emails for this stuff. It can disappear and you would never know. They dont make movies about lives being changed by missing emails like they did about letters in the olden days.
