Maintaining effective communication with influencers throughout a marketing campaign involves several practices:

1. Set Clear Expectations: From the onset, the brand should provide a thorough brief outlining the campaign goals, requirements, key messages, and desired outcomes. It’s crucial to set the foundations for what is expected and what measures of success would look like.

2. Regular Check-Ins: Regular communication helps in monitoring progress, addressing issues, and staying aligned with campaign goals. This can be via email, phone calls, or virtual meetings.

3. Constructive Feedback: Provide feedback at various stages – from content creation to post-campaign. Positive reinforcement helps maintain rapport, while constructive critiques help improve campaign results.

4. Respect Inclusivity: Respect the influencers’ creativity and audience knowledge. They know their audience best and can help tailor the message effectively.

5. Use Tools: Use advanced platforms like Flinque where you can streamline communication, monitor campaign progress, and see real-time analytics.
