Hello @NatalieS641 ,
You're free to add as many contacts as you want to your account, as long as you have permission to email them and can pay for the subscription. Pricing is based on contact tiers, which you can view on the main pricing page, or in your account under the Pricing & Plans tab (link will open if you're logged into your account) when you click the name in the top-right corner.
