These collaborations are especially common on Instagram, where brands can either publish a shared giveaway post using Instagram Collabs or promote the same giveaway through separate posts. They can also involve Facebook or other social networks, although the participation model differs depending on the platform.
In this article, we explain the main types of social media giveaway collaborations and how Easypromos helps brands gather participants, manage collaborators, and select winners transparently.
How does a giveaway collaboration work?
When planning a giveaway on social media, collaborating with another brand or influencer is an effective way to increase visibility and attract more participants. Because collaborators often have complementary audiences, these campaigns can significantly extend a brand’s reach and introduce it to potential new customers.
Collaborative giveaways can be organized in different ways depending on the social network. Some campaigns use a single shared post, while others rely on separate posts published by each collaborator. While the latter approach is simple for participants, it creates a challenge for organizers: how do you combine all the comments from different posts, profiles, or even social networks into a single giveaway and select one winner fairly?
The answer depends on how the collaboration is structured. Easypromos supports several collaboration models depending on how the giveaway is published and which social networks are involved. In the following sections, we’ll explain how each collaboration model works and how to manage participants efficiently.
Giveaway collaboration on Instagram
Easypromos supports different ways of running collaborative giveaways on Instagram. The right setup depends on how the campaign is published and how participating brands or influencers want to share it. If you’re looking for a broader guide to planning this type of campaign, read our article on How to Run a Giveaway Collaboration.
Instagram Collabs: One Giveaway, One Shared Post
Instagram Collabs is an Instagram feature that allows two accounts to co-author the same Feed post or Reel. Once the invited collaborator accepts the invitation, the post is published on both profiles, sharing the same comments, likes, and engagement.

Because participants interact with a single shared post, Easypromos can automatically import all comments and include every participant in the same giveaway. No additional setup is required beyond connecting the original Instagram post to the giveaway.
This is the simplest collaboration model when two brands or a brand and an influencer want to promote the same giveaway using one shared publication.
Collaborative Giveaways Across Multiple Instagram Accounts
Unlike Instagram Collabs, this collaboration model uses separate giveaway posts. One brand publishes the original giveaway, while the collaborating brands or influencers publish their own version on their Instagram profiles. Participants can comment on any of the posts to enter the giveaway.
When the campaign ends, Easypromos Multi-Network Giveaway allows the organizing brand to combine participants from every collaborating post into a single giveaway. This means brands do not need to redirect everyone to one original post—participants can enter through whichever collaborating account they follow.

To make this possible, the organizing brand creates a Multi-Network Giveaway and generates invitation links for the collaborating accounts. Each collaborator simply opens the invitation, signs in with their Instagram account, and selects the giveaway post they want to include. Easypromos then imports the participants from every approved post into a single participant pool for one transparent winner selection.
The setup process is simple:
- Create a Multi-Network Giveaway and select the organizer’s giveaway post.
- Generate an invitation link for each collaborating brand or influencer.
- Each collaborator signs in to Easypromos and selects their giveaway post.
- Participants from every approved post are automatically added to the same giveaway.
If one of the collaborating posts is promoted through Meta Ads, only the administrator of the advertising account can authorize access to the promoted post’s comments. The invitation system allows agencies or advertising account administrators to provide this authorization without sharing access to the advertising account itself.
Giveaway Collaboration on Facebook
Unlike Instagram, Facebook does not offer a feature equivalent to Instagram Collabs where two accounts co-author the same post. Instead, each participating Facebook Page publishes its own giveaway post and invites its audience to comment to enter the giveaway.
When the campaign ends, Easypromos Multi-Network Giveaway allows the organizing brand to combine participants from all collaborating Facebook posts into a single giveaway. Each participating Page authorizes its own post through the collaborator invitation system, allowing comments from every approved post to be imported into the same participant pool for one transparent winner selection.

The process is very similar to collaborative giveaways across multiple Instagram accounts:
- The organizing brand creates a Multi-Network Giveaway.
- Invitation links are sent to the collaborating Facebook Pages.
- Each collaborator authorizes the giveaway post they want to include.
- Participants from every approved Facebook post are automatically combined into a single giveaway.
If one or more giveaway posts are promoted through Meta Ads, the administrator of the advertising account must authorize access to the promoted post’s comments. The invitation system makes it possible to provide this authorization without granting access to the advertising account itself.
Giveaway Collaboration on Facebook and Instagram
Some collaborative campaigns span both Facebook and Instagram, allowing brands to engage their communities across the two platforms through a single giveaway. In this type of campaign, each collaborating brand publishes its own giveaway post on Facebook, Instagram, or both, and participants can enter by commenting on any of the eligible posts.
With Easypromos Multi-Network Giveaway, comments from eligible Facebook and Instagram giveaway posts are imported into the same giveaway, making it easy to combine participants into one participant pool and conduct one transparent winner selection across both platforms.

This approach is ideal when collaborating brands have audiences on different social networks but want to manage a single campaign with one set of participation rules, one participant pool, and one winner selection process.
Collaborative giveaways are an effective way to increase brand visibility, expand your reach, and engage new audiences. Using a reliable giveaway platform also helps ensure a transparent winner selection process and provides a Certificate of Validity to reinforce participants’ confidence in the campaign.
Note: Facebook does not support a feature equivalent to Instagram Collabs. Instead, collaborative campaigns on Facebook use separate Facebook posts, which can be combined with Instagram posts through Multi-Network Giveaway.
Giveaway Collaboration on Other Social Networks
When collaborating on social networks that do not support participant consolidation, such as X or YouTube, the simplest approach is to publish the giveaway on one social network and ask collaborators to promote that original giveaway from their own channels.
Instead of creating separate participation experiences, collaborators direct their audiences to the original giveaway post, where everyone follows the same participation rules and enters the same giveaway.

This approach is particularly useful when running campaigns across social networks that do not support automatic participant consolidation. It keeps the giveaway simple to manage while allowing every collaborator to help increase its visibility and reach.
