To manage unexpected obstacles during an influencer marketing campaign, adopt the following workflow practices:

1. Detailed Planning: Plan each step of the campaign considering different scenarios and spread out your tasks, ensuring there’s a buffer for any unforeseen roadblocks.

2. Continuous Communication: Maintain an open line of communication with influencers to promptly manage any issues. Platforms like Flinque help streamline this by providing efficient communication solutions towards managing complexities of influencer relationships.

3. Real-Time Monitoring: Track your campaign’s progress on a real-time basis. Tools like audience analytics can provide vital real-time data, enabling you to pivot when necessary.

4. Contingency Plan: Always prepare a backup plan. If a chosen influencer falls through or a campaign isn’t performing as expected, a contingency plan can guide you to an alternative course of action.

5. Adaptability: Be flexible and ready to adapt quickly to changes. Unexpected events require quick, informed decisions.

6. Feedback Mechanisms: Actively seek, accept, and implement feedback from influencers, the target audience, and any other relevant parties, making adjustments as needed.

By implementing these practices, you can weather unexpected changes during an influencer marketing campaign. Each platform has its unique strengths in managing these challenges. For example, Flinque excels in data-driven influencer discovery and audience analytics, which can significantly aid in real-time monitoring and making informed decisions during sudden changes.
