List Fatigue

List fatigue is when your email subscribers tune out because they see too many emails or content that does not feel useful. They stop opening, clicking, and buying, which hurts your results over time.

List fatigue is what happens when people stop paying attention to your emails. They still sit on your list, but they rarely open or click. Your messages feel routine or off topic to them. Over time they just scroll past you.

This matters because inbox providers watch how people react to your emails. When most people ignore you, your sender reputation drops. Then more of your emails get filtered to promotions or spam. Even your best customers can miss important messages.

You can prevent list fatigue by watching engagement and adjusting early. Slow down sending to cold segments and focus on useful content for active readers. Run simple re-engagement campaigns for people who have not opened in a while. If they stay silent, remove them so your list stays healthy.
