There are 3 ways in which you can invite customers to your portal, so they can start voting and adding posts.
Start by navigating to "People" and then select the option "Invite Users". Then you'll find the 3 options.
You can easily invite one or more customers at the same time, by letting ProductLift send an email. Just fill in the email address and the name of your customer and ProductLift will send the email.
Share the link to your portal with your customers. This can for example be useful on social media or directly inside your app.
In this option, you can invite your customers by sending them an email yourself. You can use the email example shared by ProductLift.
