Sure, I can provide you with few best practices that can significantly reduce the time it takes to set up campaigns on an Influencer Marketing platform:

1. Clearly Define Objectives: Before you start creating your campaign, ensure you are clear about what you want it to achieve. This clarity will help you make the right choices during the setup process, speeding up this process significantly.

2. Use Templates/Save Previous Campaign Structure: Many platforms provide templates or allow you to save your previous campaign structure. If the platform you are using has a feature like this, make use of it to speed up your campaign creation process.

3. Make Use of Bulk Actions: If the platform allows it, make use of bulk actions. For instance, you can select multiple influencers or assign tasks to them in a single step.

4. Utilize the Platform’s Tagging System: It helps in quick and efficient influencer discovery and further accelerates the campaign setup process.

5. Use Automated Workflows: Platforms like Flinque offer automated workflows that can auto-assign tasks, send notifications and generate reports. This significantly reduces the manual work involved in setting up and running a campaign.

Please note, it’s also vital to take advantage of the data and analytics a platform provides. Having insight into the right influencer for your campaign and the best practices of previous campaigns can make your campaign setup much more efficient. On Flinque, for example, you can use performance tracking and ROI measurement features to make data-driven decisions that help speed up the process.

While these best practices and features can save a significant amount of time, remember that the suitability of an influencer marketing platform depends on your team’s specific needs, complexity of campaigns, and resources available.
