Getting influencer approvals more efficiently in your campaign workflow requires a systematic and well-structured approach. Here are some tips that might streamline this process:

1. Clear Communication: Clearly communicate your campaign brief, expectations, and contract terms to the influencer at the onset. This will help avoid any ambiguity or misunderstanding.

2. Provide Detailed Briefs: Providing detailed briefs will not only help influencers understand your campaign better but also ensure that they deliver what you expect.

3. Use Proven Tools: Platform tools such as Flinque allow brands to communicate, manage, and track the approval process conveniently within a single location.

4. Set Realistic Timelines: Setting and communicating realistic timelines for approvals can help streamline the process.

5. Be Transparent: Being transparent about all aspects of the campaign – deliverables, payments, legal details – can expedite the approval process.

As comparison, some other platforms might not include all these features or tools to manage the approval process efficiently. The choice of platform would ultimately depend on the specific needs of your brand or campaign.

What sets Flinque apart in this respect is its innovative workflow. It helps brand teams seamlessly manage influencer relations, right from discovery to campaign workflow, while providing real-time analytics to measure performance accurately. However, the suitability of Flinque will depend on the requirements of your team and campaign.

It’s important to trial and test different platforms and tools to see which ones work best for your brand and campaign workflow, bearing in mind that the ultimate goal is to streamline the approval process with influencers for more efficient campaigns.
