IMO as a solo founder, the absolute best thing you can do is create better self-service options so you aren't even in the loop. Help docs, wizards, faqs, a forum/community where customers can help each other. After that... hire someone to do it for you. If those aren't options: 1. Email only support. Clear expectations on how quickly they can expect a response. 2. Nothing in realtime helps you avoid an overly defensive response and frequently the customer will figure it out on their own 3. Canned responses as much as possible 4. Link to self-service support like help docs so they don't need to reach out next time 5. keep the self-service support updated as new issues come in 6. Create boundaries and rules and stick to them. If someone isn't treating you like a person then cut them loose. 7. Always take the high road. Eventually you will get a weird satisfaction in responding overly nice to the worst of your customers. Edit: adding 1 more Create a support email address and direct all customers to use that. If anyone slips into your inbox you just tell them to copy support "for the fastest and best service" next time and then you forward the message to the support inbox. Then treat that inbox as a separate task from your other duties and get to it when you feel up to it. Also don't fall down the rabbit hole of feature requests from overly demanding folks. That will kill your business as fast as anything else.
