I'll take a more extreme position on this question. You're setting yourself up for failure by asking us how to "defend" your messaging. Instead, I'd ask you to listen to those people who you are used to "defending" your messaging from. It's not your messaging - give up that pride of ownership in order to listen and learn from sales, product, and your executives if they choose to care about your exact phrasing. That doesn't mean that they get to write the exact words - but all of those constituencies have an important point of view, and it's your job to triangulate among them, decide where to give weight, and come up with messaging that is clear and compelling. When you think you totally have that message nailed, you're not finished. You're at step 1. Next, you need to test that messaging with real, live customers. Don't look just for confirmation of your message - lean into those people you interview who find your amazing messaging confusing or bland. Figure out how to make it right. This is an involved process, but it's amazingly powerful. Then, by the way, when someone comes and says "hey that message isn't that great, how about XYZ" you can say "well, we crafted this message with your input and the input of other leaders, then we shared it with customers and made ABC changes based on their feedback, and this is where we landed."
