Use the emoji for positive emotions liberally in social media posts, forum comments, and support messages as long as both you and the customer are feeling good about the situation.
Example emoji:
😄😊😉
Do not use emoji for negative emotions at all, unless you know you and your audience share the emotion. For instance, on the day Tim Berners-Lee dies, a ☹ would only be appropriate.
Example negative emoji:
😡😞😪
