Email app or script to identify and forward or alert by SMS user of important emails

I am seeking a solution to my overwhelming amount of emails. I am looking for emailing handling sysem that can identify (or identify) important senders (contacts) along with some generic identifiers, such as domain, or human. When important emails come in, I am notified through SMS to my phone. It would be ideal if it can forward the email content as well. My reply will be back through email. Assume email platform is Microsoft 365 or Exchange. It can be App, bot or script.
