This functionality is good to use, if you want to send out a link to a group of existing members or a group of players that you think they should buy. When a player press the link, the view in the webbrowser will only show that membership and not other memberships.
This is the view when you have clicked the link:
Where do I find the link?
Go into the club portal club.sweetspot.io and select the Membership / overview section:
2. Select the membership
3. In the upper right corner you find the button: "Checkout link"
Add that link to the e-mail that you are planning to send out to.
