Cover the common reply set
Start with yes, no, love it, crying, shocked, excited, angry, bored, side eye, thinking, good night, and thank you. This gives users a reason to open the pack often.
Make faces expressive
The face should explain the sticker before the caption is read. Large eyes, clear mouths, and strong gestures make reaction stickers easier to understand.
Test against busy chat backgrounds
A sticker needs enough outline and contrast to work on light bubbles, dark mode, photos, and mixed message threads.
