I need a FB messenger that will let me message the user in a group. I want to be able to automate sending messages to users of a group that I own, but there are some users I don't want to message. So Ideally, it would be nice to be able to specify which user to message or which to not message. Also, I'm not sure if there are limitations and if exceeded could cause a temp ban. So having a self-defined delay between the messages may be wise. I would think there is something turnkey that exists, but I guess I will develop if necessary. Any help appreciated.
