Partnering with other Instagram accounts to do collabs (paid or not) and joint giveaways is a great way to reach more people.

Instagram has built-in Collabs support, which lets the accounts share a post that appears in their feeds to reach more people.

If you've never used the Instagram Collabs feature, it's easy to use. You just invite your collaborators during the Instagram post setup flow. See the screenshots below from Later's Instagram collab guide.

We also highly recommend that the other accounts you collaborate with set the quiz link as their biolink (or on their link in bio page) for the duration of the giveaway.
