Use candid beta customer reactions to your new feature or product (like Intercom did with its Fin launch) to build launch hype.
Nobody cares about the "new product/feature launch" email describing new functionality.
Instead, go against the grain and create a sizzle reel of reactions from early access customers to show off your new product or feature.
Aside from creating a buzz, you can also get those early access customers in on the promotion strategy by having them share the post, amplifying your reach.
