Identifying the signs of overwhelming volume can help you take corrective action before it affects your entire campaign. Look out for:
High Unsubscribe Rates: A significant increase in unsubscribe rates can indicate that your email volume is too high for your audience. Low Engagement Rates: Consistently low open and click-through rates may suggest that subscribers are ignoring your emails. Increased Spam Complaints: A rise in spam complaints is a clear signal that your emails are not being well-received. Negative Feedback: Direct feedback from subscribers about receiving too many emails should not be ignored.
