When people label an email as spam, it usually means the message felt unexpected, too promotional, or unrelated to what they wanted. A good first step is to check how often you send emails and make sure you are not overwhelming the inbox. It also helps to review your subject lines because some phrases can look misleading or too sales-focused. Allowing people to change their preferences can also reduce complaints. If they can choose topics or reduce frequency, they feel more in control. Cleaning your list by removing inactive contacts can also protect your reputation. What changes do you think help reduce unwanted spam complaints?
