You might realize that automated messages (happen when World Power restarts, or you go in a store) always begin with:
[Store name] Hello! Welcome! et c.
or
<!> ! Whispers to you: Welcome to this store!
Those look very unprofessional and not like a warm welcome. With the /tellraw command, you can display in the chat EXACTLY what you type, without any pre/suffixes.

Clearly, you can see, it is more professional. It is better than /msg because it doesn’t have any text beforehand, and it is better than /say because /say always says the command to everybody.

How to use /tellraw:
Here is the command syntax:
/tellraw <Person(s)ToTell> <MessageToTell>
For PersonToTell, use Target Selectors, such as @a, @p, @s, @r, et c.
For MessageToTell, you will need to type text in the JSON Text format. Here is a useful tool for automatically turning normal text into JSON format. Click here!
