Can I Control Who Sees My Feature Announcements?

Yes. On a Capture's Targeting tab, click Add New Rule and pick a rule. These are the useful ones for announcements:

• Visitors: New or returning visitors
• Geo-Location: Visitors from the countries you pick
• Schedule: Set dates and times only (Business Plan and above)
• Triggers > Selector: When an element is on the page, or contains a value (Business and above)
• Triggers > Javascript: Your own function decides, such as a logged-in user's plan if your page exposes it (Business and above)
• Triggers > Times Shown: How often one person sees it, per visit or ever

Every rule in a group has to match. To announce a feature only to returning visitors in the UK, for example, put a Visitors rule set to returning and a Geo-Location rule for the United Kingdom in the same group. On the Premium Plan you can add more rule groups, and the Capture shows if any group matches.

Every Capture also starts with two exclude rules, so people who've completed or closed it don't see it again.

The Rules Overview covers every rule type.
