You did it! You're officially married to your best friend and pulled off the best celebration of the year. However, just because the planning is done and the party has come and gone doesn't mean your bridal tasks are over. There are several boxes to check before your era as bride comes to an end. If you're unsure where to start, turn to the most important part of your wedding: your guests. That means promptly writing thank you notes and sharing any advance photos on your wedding website—they want to see them just as much as you do! Read on for your official list of post-wedding responsibilities.

Say thank you.

This is by far the most important item on the list. Your guests were generous with their time (and many with their gifts), so take the time to say thank you. For gifts you receive at the wedding, try to get thank you notes out within 60 days. While a pile of 200-plus cards staring you in the face may be intimidating, break it down. Spend just 30 minutes each evening writing a few cards. You'll have them done in no time.

Add photos to your wedding website.

Whether you have funny Instagram photos from the party or an advance series of shots from your photographer, upload a few to your wedding website. After all, your website isn't just for the pre-wedding details—your family and friends want to see those wedding and honeymoon snaps. While social media is also a great place to share, posting the photos on your site streamlines all photos into one place, without clogging up your guests' news feeds.

Clean or preserve your dress.

Spilled champagne, sweat, and dirt can leave your wedding dress a bit of a mess at the end of a fun night. Whether you're hoping your future daughter might wear your gown one day or you're planning to resell it, get your dress cleaned or preserved as soon as possible.

Change your name.

Planning to keep your maiden moniker? Sweet! One less to-do for you. If you're planning to change your name, it's not Facebook or Instagram that's the problem. It's the long arm of the law. Make the process as painless as possible by collecting all the necessary documents, including your marriage license, Social Security card, driver's license, and passport. Be sure to check your state's requirements for any additional paperwork you can fill out before you get started. The sooner you get this out of the way, the happier you'll be, and the sooner you can use your new new monogram.

Use your registry-completion discount.

There will probably be a few things on your registry that you don't get. Grab any gift cards and plan a fun day at the store finishing out your registry. Don't forget to take advantage of your registry-completion discount before it expires (this can be anywhere from one to six months after the wedding).

Return duplicate gifts.

Don't need three coffee makers? We didn't think so. But this scenario is very possible if people shopped at the same time or just don't understand the idea of a registry. And it's not just duplicates. There may be a few things you receive that just aren't your taste. Exchange them for something you really like or need.

Sell any extras.

If you were a DIY bride down to the last detail, don't let all of that hard work go to waste. Whether it's mason jars or hundreds of skeleton keys or accessories for the photo booth, get your money back where possible. Post your treasures on eBay, Etsy, or Wallapop. You can even resell your dress on a site like Poshmark if you're not the sentimental type or don't have the space to store it.

Relax.

Yes, there is a huge list of things to get done. But don't get so lost in the post-wedding to-do list that you forget to savor the moment. If you're lucky enough to hop on a plane a day or two after the "I dos," enjoy it. Spend time with your spouse, soak in the time away, and ride that post-wedding high as long as you can. Your list can wait until you get home. Planning a delayed honeymoon? Try to shut yourselves off to the world even just for a day or two before tackling your to-dos.
