I am designing an app that has different pricing tiers with specific features tied to the tiers. We currently have a tier 3 feature called zebras that will be added to/accessed from an existing drop-down menu. It has been suggested that we add a greyed out text option of zebras to tiers 1 and 2 with a tool tip to inform users that they can have zebras if they upgrade to tier 3.
I believe that the user would rather not have a UI element crowding the interface and I don't want a paying customer to feel like we are constantly telling them what they cannot do with our product and forcing marketing on them.
What are some in-app light touch approaches, other than an upgrade button that can be utilized in this situation. Also, is the greyed-out text approach as bad as I feel it is or am I over-reacting?
