Giveaways work like quizzes, where you can collect email opt-ins and choose to include products for recommendations (optional).
Once your giveaway is created, the POPlink is the most common way to share a giveaway since it works well on social. For example, on Instagram you'd add it in your link in bio and tell customers how to enter in your post.
The big differences with giveaways are:
You can set an end date when the giveaway will close for new entries
You can pick a random winner on the submissions with the built-in winner picker feature.
If you have any questions or need any help, just ask!
