One of the core principles of gamification is feedback, where user actions and decisions are rewarded by a positive response. This principle can be implemented in your product quickly and efficiently, with a transactional email sent whenever a user performs a certain action, or achieves a certain goal.

This simple action of sending a ‘Well done!‘, ‘You generated X leads this month!’ or ‘You ran X miles today!‘ message can help users to feel engaged with your product, appreciated by your company, and motivated to continue using your product in the future.
