Avoid being pushy

Don't compel users to provide feedback when they're unsubscribing. Instead, consider it as an optional and voluntary action. Users may find themselves in situations where they're pressed for time, not in the best mood, or simply in a circumstance where typing out feedback is inconvenient. Regardless of their specific reasons, it's crucial to value and respect their time.

Opting for an optional feedback process also benefits you. It ensures that the insights you receive are more likely to be relevant and meaningful. When feedback is made mandatory, users may be inclined to type random or hasty responses just to fulfill the requirement, which may not offer genuine insights.
