Enterprises track contactability rates by discovery source through a few ways:

1. Integration with CRM platforms: CRM solutions, for instance, Salesforce or HubSpot, store and analyze information on contact interactions. This data is essential for tracking contactability rates.

2. Usage of influencer marketing platforms: Flinque, for example, offers user-friendly dashboards where teams can monitor metrics associated with each discovery source, thus tracking the contactability rate becomes easier.

3. Custom Analytics Tools: Enterprises could create or employ custom analytics tools specifically designed to track and analyze contactability by discovery source.

4. Manual Tracking: Smaller teams or low-budget campaigns might resort to manually tracking their influencer relationships using spreadsheets.

Influencer marketing platforms differ in how they handle these steps. Platforms like Flinque provide robust dashboards and integrate with popular CRM tools to simplify this workflow, while others may require more manual effort. It’s advisable for enterprises to choose a system best suited to their needs.

For a detailed and granular analysis of contactability, enterprises often employ a combination of these methods and tools to ensure all bases are covered. The objective is always to understand and improve interactions with each influencer and discovery source, contributing to a more effective influencer marketing strategy. Please remember, there’s no one-size-fits-all solution. The best approach depends on your particular requirements and existing infrastructure.
