How to reduce user-level spam actions?

Reducing spam button usage:

Set expectations: Tell subscribers what they will receive and how often. Meet those expectations.

Deliver relevance: Send content recipients actually want. Irrelevant mail gets marked spam.

Easy unsubscribe: Make opting out simple. Users who cannot find unsubscribe use the spam button.

Honor preferences: Respect frequency choices and content preferences.

Proactive removal: Remove disengaged users before they mark you spam.

Every spam mark damages reputation. Make it easy to leave gracefully instead.

Let dissatisfied passengers disembark politely rather than forcing them to signal distress.
