Thank you notes are a must!!! It is you formally saying thank you after all the chaos that was the wedding day. You should never open gifts in front of people therefore you hadn't had a moment to thank the person for gifting it to you. You get a chance to mention something personal about them at the wedding as well to tell them that they weren't just another face in the crowd and you appreciated them taking the time and effort to make it to your event.

Also if your signature makes my scrolling mess up "you're tacky and I hate you."
