Note: if your email is not run by a Microsoft exchange server, the you must leave your computer turned on and Outlook running for the automated replies to be sent. If you’re not sure if your email is setup in this way, ask your IT department. If you don’t have an IT department, then your email isn’t likely setup on an MS Exchange server and you should leave your computer on.
The ideal type of opinion (unrelated to your expertise) is one that doesn’t offend anyone, but makes some people relate to you more. For example, I’m a vegetarian. I used to protest whenever there wasn’t a big piece of meat on my plate. But when I tried eating just veggies for a couple of months, I realized I felt a lot more energetic. Sure, it’s more ecological. And often animals are treated cruelly. But those aren’t the things I emphasize if someone asks why I’m a vegetarian. No one in their right mind has a strong negative reaction to someone eating food that makes them feel energetic, right? But for some vegetarians it’s a very meaningful choice, so it might have a positive impact on those people. That said, I highly doubt that my choice of diet have any direct impact on my sales.
