Several indicators can signal that you are overusing email marketing:
High Unsubscribe Rates: If a significant number of recipients are opting out, it's a clear sign you're sending too many emails. Low Engagement: Declining open rates and click-through rates suggest that your audience is losing interest. Spam Complaints: Frequent complaints about spam can damage your sender reputation and deliverability. Negative Feedback: Direct feedback from your subscribers expressing frustration or annoyance.
