Email list fatigue is a possible issue if conversions from email marketing deployments decrease. While it is often due to old subscribers in your list, it can also be due to stale or repeated messaging, or the information provided is no longer relevant or of interest to the recipient.

Email list fatigue occurs when subscribers stop engaging with your email marketing campaigns. Email list fatigues occurs for three primary reasons:

• You send email too frequently, which burns out your list
• Your emails are not relevant enough to the audience on your list
• A subscriber that was once part of your target audience has a change in their own life, and engages less frequently
