Instead of answering the same questions over and over, why not create a Frequently Asked Questions blog post in which you give in-depth, definitive answers to the questions?
When creating your FAQ blog post, try to be thorough and answer as many questions as possible.
Your goal is to create a resource to which you can send people again and again. A document that will stand the test of time. When they email you with a question, you want to say, “Here’s a document I created in which I answer that question.”
If you don’t feel like creating one long FAQ document, you could write a series of blog posts to answer one commonly asked question in each post. That way, when someone asks a specific problem, you can point them to a particular post.
However you do it, be sure to answer the questions in as much detail possible. You don’t want people sending you follow up emails with more questions after they read your post. You want to try to answer each question in as much depth as possible.
Over time, you can add to your FAQ post as people ask more questions. It can be a “living document” of sorts, which continues to grow, change, and evolve.
