And yes, just like any other effective marketing tools, you want your postcard to be worth keeping, or at least worth glancing a few seconds more than the rest.
If you are looking for thank you postcard ideas to send to your customers, this article can help you with just that! I have done my research, and discovered that of the 100s “thanks for your business” postcard design ideas, only a handful that I think stand above the rest.
Without further adieu, here are 5 “thank you” postcard design ideas you can use:
1. Cartoon postcard
Well-designed cartoon postcards are attention-grabbing due to the design. Add funny message to that, you can expect your customers will keep yours, even share with their colleagues, family and friends.

2. Thank you + promotional postcard
Saying thank you for your client’s business is wonderful, but adding a bit of promotional to go with your thank you postcards is simply smart!

3. Thematic postcard
Thank you postcards that show your business’ unique design elements can help your branding endeavour.

4. Black and white postcard
Black-and-white postcard is always striking. Usually emphasising on design elements, these kinds of artsy thank you postcards are worth-keeping.

5. “Designer” postcard
Typically simple in design, a “designer” thank you postcards shout “keep me!” to the recipients. If you can say thank you while adding a bit of promotional messages inside, these kinds of postcards will help you gain repeat customers.

I’m sure there are a lot more thank you postcards that are probably better-designed than the five I suggest above… so, if your business has incorporated thank you postcards in your customer relationship campaign, please share your design and message!
