For accessible emojis:

1. Use them sparingly as the screen reader will read them all.
2. Use them at the end in order to keep the sentence consistent.
3. Keep words instead of emojis: the words convey a better meaning.
4. Avoid them in bullet lists
5. Avoid emojis to convey an information
6. Context can be misleading in the use of the emoji! It emphasizes points 3. and 5.
