Ask HN: How to manage inbound calls/ emails/ texts etc.

I am very bad at this.

If you're running a business or working at one with lots of customers reaching out across channels ... what system do you use?

CRMs are hit or miss for me. I just keep a text file open with the stuff i need to follow up on when something does come in. But I lose context and can't prioritize right, or I just forget, then people get annoyed.

There has to be a better way ... right?
