Open rates often drop when people get used to your messages and lose interest over time. The first email usually gets attention because it feels fresh, but later ones may not feel as exciting if the content becomes too similar. If readers expect long or repetitive messages, they may skip them. Sending emails too often can also make people feel tired. Sometimes the subject line does not give them a clear reason to click. Refreshing the style, spacing out emails, or changing your topics can help fix this slow decline. What kind of change do you think can make people curious to open your later emails again?
