A personalized 21st birthday card done right

eCards were one of the first viral hits of the 1990s internet. Unfortunately, they also became synonymous with cheap, ad-laden sites flashing outdated stock images. If you were wondering “How can I show someone I care…but not really?” – eCards were the unfortunate, but true, digital answer to your question.

But not anymore.

With Kudoboard, you can forget about the corny images, popup ads, and spammy looking emails. Instead, you can easily create an online card with photos, GIFs, videos, and messages celebrating your recipient’s 21st birthday. You can even invite others to participate to make it a unique group card.

Frequently Asked Questions about 21st Birthday Cards

A 21st birthday eCard from Kudoboard is a digital way, as an individual or a group, to celebrate someone in your life turning 21. For the individual who is tasked with picking out a card for everyone to sign, spending hours in card aisles hoping to find the one that fits the circumstances (and personalities of everyone involved) can be difficult. With Kudoboard, you can custom-create a board to compile everyone’s virtual “21st birthday wishes” right from your computer or phone. On your board, you can add messages, GIFs, images, or videos so that the birthday card can be personalized to the recipient. This makes a great option for those living farther away to still join in on the celebration.

Yes, for many countries around the world, the 21st birthday is one that is celebrated more grandiose than other years surrounding it. Here in the United States, the 21st birthday is seen as the year in which someone becomes an adult. Even though 18 is technically the legal age of adulthood, many bars, casinos, and other venues deny access until the age of 21 due to the serving of alcohol. U.S. law states that 21 is the age at which one can purchase and consume alcohol, so many people celebrate the occasion by drinking the night away with their friends and family. Whether or not someone wants to drink or not, 21 is a birthday that is excitedly looked forward to!

Handmade or storebought cards have been the standard when it comes to birthdays, and for good reason. They give us a chance to say what we need to the people we care about on their special day. Virtual birthday cards, or eCards, have begun to gain popularity and we personally think they deserve a high ranking as well. Here’e why:

  • They are Convenient: no driving to the store or spending hours trying to make your own. With just a few clicks you have not only created the card but sent it as well.
  • They Last Longer: A virtual card can’t have a cup of orange juice spilled on it, or accidentally trampled by your dog when she has the zoomies. It is tucked away safely to pull up whenever you need it.
  • They are Nice to Mother Nature: In a time where we are all trying to be more environmentally-conscious, choosing an eCard over a paper one is a small choice to help make a big difference
  • They are Customizable: Kudoboard 21st birthday cards are made to be exactly how you want them to be. No more searching aisles wondering how you are going to find what you need. Just hop on our website and in minutes you will have a personalized gift for whoever is turning 21.
  • They are Fast and Easy: Whoops – your niece is turning 21 today instead of next week like you thought? No worries here! Choosing a virtual option for her 21st birthday card means you can have something set up in less than 10 minutes (and she never has to know this wasn’t planned all along).

You no longer have to worry about whether or not you are a masterfully skilled birthday-card-maker, because Kudoboard has your back. We have made this process so simple, anyone can do it!

Once you click on that blue “create a kudoboard” button, our template will walk you through each step of the card-making process quickly and easily. You will be prompted to input the name of your recipient, a name or title for your board, and to select which type of board fits your needs best (birthdays & celebrations). From there, try out a variety of backgrounds until you find the right one. Voila! Your board is created. Now that we have taken away the time-consuming stress of actually making the card (like the hours you spent last year on that candy bar birthday card), you can use the rest of your time filling the board with all of the 21st-birthday love your recipient deserves!

That is the money question, isn’t it? In our opinion, this is the most important part of the card; the make-it-or-break-it piece (no pressure). No one knows your recipient the way that you do, so only you can really know what they will want to hear. We aren’t the kind of friend to leave you stranded though, so below are a few ideas to get you started depending on what kind of 21st birthday card you need:

  • Funny:
    “R.I.P. to your fake I.D. Congrats!”
  • Sarcastic:
    “Finally! Now you can legally do everything you’ve been doing for the last 5 years.”
  • Romantic:
    “If I had to do the last 21 years over again, I would find you sooner and spend every extra day with you I could. I love you!”
  • Cute:
    “Happy birthday to my favorite reason to buy presents and eat cake! (and now take shots with!)”
  • Puns:
    “Happy 21st! Lets get trashed! (with a picture of some raccoons next to it)

Whoever you need one for! Kudoboard makes it easy to customize it according to your recipient. Grandma needs a card for her granddaughter? Check. Dad needs a card for his nephew? Check. You need a card for your twin BFF’s? Check and check. Whichever person in your life is turning 21, our virtual birthday cards are the way to go!

Pricing for your 21st birthday eCard varies depending on your need. Kudoboard offers a free mini-board to anyone needing 10 or fewer posts on their board. Our premium board, which is our most popular, is $5.99 and allows for up to 100 posts and the option of adding videos. This would give you plenty of room to put as many things on the board as you want, and even invite friends and family to join in! From there, we have a variety of options for larger groups, companies, or milestones that start at $20 a board.

For larger events contact us for custom pricing.

Yes! That is one of the aspects that Kudoboard does best. While it is great to have the ability to give your friends and family a virtual birthday card just from you, it might be even more meaningful to include other important people in their life. Picture their face when they click on the link and the screen is filled with pictures, messages, and videos wishing them a happy 21st birthday. That is sure to be something treasured for a long time.

Our free mini-board allows for up to 10 posts. It’s perfect for just you or a couple of other individuals to wish someone a happy 21st birthday. Our most popular birthday board, our premium board, bumps you up to a 100-post maximum for $5.99. The premium board also gives you the perk of adding videos to the online 21st birthday card. With this option, you can send a link to all of your friends and family inviting them to contribute to the board and join in on the fun.

We know that, sometimes, just having a digital option for a 21st birthday card isn’t enough. That’s why we have printing options for you! Kudoboard allows the option to have the board printed as a beautiful, hardbound book, or as a high-resolution poster.

Once your board is full of the posts you want, you can select the option to have it printed as a book so a 21st birthday can be remembered in a tangible way. Our books come with a 7”x7” hardcover and have an image-wrapped, matte finish. We ship anywhere in the US, or to many countries worldwide.

If you choose to have the virtual 21st birthday card printed as a poster, you have the option of 12”, 24”, or 48” wide. We can print and ship you a beautiful, semi-gloss poster, or you can download a high-resolution image of your board and print it on your own.
