Minecraft Server opening greeting?

I would like to set up an "initial greeting" on my Aternos server.

For example: Welcome to my server.

This should be written in the chat with the player when he enters the server.

Can someone tell me how to do that?

Either look for a welcome plug-in or use essentials, there you can enter the greeting and farewell.

Thank you 😃

Welcome to the grave digger's field or something. Simply very creative and suitable!
