Lead fatigue happens when a prospect disengages due to excessive, irrelevant, or repetitive communication from a business. Overloading leads with generic emails, aggressive sales calls, or frequent ads can result in decreased engagement and higher unsubscribe rates. Businesses combat lead fatigue by segmenting audiences, pacing outreach, and personalizing messaging. CRM insights help identify engagement drop-offs and adjust strategies accordingly. Reducing lead fatigue ensures a healthier sales funnel and better long-term customer relationships.
