When your promotion is 'private,' you need to generate invite URLs for each individual you wish to invite to enter
What are InviteLinks?
When you make your promotion 'Live' via the Launch Control page, you will be asked to choose if entry to your promotion is Public (anyone with a single link to the promotion can enter) or Private (only people you individually invite with their own unique URL can enter).
InviteLinks is the name we've given to these secure one-use URLs that allow one entry to your promotion. Learn more about Public and Private Promotions here.
What are Personalized and Anonymous InviteLinks?
Personalized InviteLinks
The great thing about inviting someone to enter your promotion with an InviteLink is that you likely already know their email address and perhaps information about them, such as their name, a product they purchased from you, etc. If you want this information recorded against their entry (for reporting purposes or to display on the promotion pages), then you can select to create a Personalized InviteLink and choose which fields to add. You then just need to make sure the right person enters via the right InviteLink. (You may wish to switch off the Enter page in your promotion if there is no further data you wish to collect from entrants).
Anonymous InviteLinks
If you would rather not create person-specific InviteLinks, you have the option to create Anonymous InviteLinks, which can be given to anyone to choose from and will allow one entry to your promotion. If you want to collect any information from this entrant so you can identify their entry, then you can add an Enter Form to your promotion to ask for their details.
How do I create and manage my InviteLinks
InviteLinks are created and managed in the Share Centre you can read more about that here.
