As counterintuitive as this may sound, simple messaging isn’t always the way to go. It really comes down to your target buyer(s) and the set of messages that resonate with them, which may need to be simple for a line of business buyer like Marketing or HR or more complex/technical for an IT/Developer buyer. But it always comes back to understanding your target audience and their pain points, and ensuring you're tailoring your messaging for them.
Also, depending on the channel/medium where your messaging is shared, it may necessitate varying altitudes. For example, Social Media is a clear channel where you need to keep your messaging short and sweet whereas a blog is a channel where you can go more in depth.
I love this question! This is one of my favorite parts of product marketing - getting to translate deeply technical concepts into what actually matters. As much as possible, I encourage you to dig into the technology. Spend time with your product and engineering teams to really understand what is being built and why. And don't be afraid to ask lots of questions! That's how we learn. And continuously asking why something matters or how it's different is a great push on those teams to get crisp on their responses to customers too.
Take the time to stay up on the latest in the industry too. Check out presentations from competitors and listen to podcasts/webinars/etc. It's a great input to get ideas on what works and doesn't. And a great way to uncover more questions or new information on technologies.
And always review your messaging to see if it's too jargon heavy or if you're simple describing a feature. What the feature is matters much less than the impact it has on customers. Start with why it matters before trying to talk about your own product.
After working through Positioning, I will build Messaging from the bottom-up. The bottom-up approach automatically encourages you to elevate your messaging from technical details and features. More specifically, I build in this order: Features -> Benefits -> Value -> Message.

This approach has served me well to create a natural balance between technical details (Features) and emotion (Messages).
