Look past emoji speak, i.e. 🙈🙉🙊 = See no evil, hear no evil, speak no evil.
The utility of an emoji goes well beyond a fun way to “speak” to each other over your messenger tool.
Use them to create a common understanding, personalization, or a unique identity. They are also great for driving faster user adoption and helping users navigate their tool faster. Many of us are visual learners. We need to see information in order to retain it. Visuals, like an emoji, add to the communication flow in a way that written or verbal communication do not.
