Drive product signups by requiring entrants to subscribe and provide you with their username or user ID.
With this easy-to-use giveaway template you can incentivise signups and increase product subscriptions by giving away a prize such as a free subscription or upgrade and getting users to unlock chances to win by signing up to your product or a free trial.
If you want users to sign up to a paid subscription to enter you will need to be aware of the No Purchase Necessary laws that apply to you. but don't stress, as Gleam has a built-in Alternate Method of Entry that will automatically be available where required. Just make sure you tick "A purchase or donation is required for users to complete this Action" in the template setup form.
