Many of the new feature announcements that appear automatically each week now relate to features only available in specific plans. This is usually only mentioned in the body of the message.
I would request that Aha make it clear at the top of each announcement what plan or plans the feature is available for. Even better, have a config option that only allows announcements for your plan level to be seen.
This avoids setting false expectations and reduces wasted time.
I appreciate that you want to "market" your new features but disturbing everyone with features they cannot get is frustrating. Most enterprises control the plan level centrally. Individuals cannot decide to change plans.
