TLDR:
Include CTAs in every CMS Hub and/or Marketing Hub Tier, starting with 3 in Free, 5 in Starter, and unlimited once you get to Pro and Enterprise.
Who:
marketers, web designers, web developers, theme developers, anyone using CMS Hub to grow their business
Goal:
Allow access for all tiers to purchase paid themes that require CTAs due to how modules are developed to incorporate CTAs and buttons and eliminate unnecessary theme migrations from free to paid themes.
Value:
A CMS Hub free user could opt to buy a Pro level theme and grow into CMS Hub (and other hubs). It would allow them to build their website once with the theme of choice and not have to worry about compatibility or migrating their website later. It would essentially allow all of the themes in the marketplace to be available for all customers.
Examples:
Many other tools within HubSpot are structured this way, such as included marketing contacts or even number of snippets, templates, etc.
