Monitor Email Campaign Metrics

Analyze Bounce Rates and Spam Complaints

This can make your future emails go to spam.

Spam complaints are also very important. This happens when recipients mark your email as spam. Even a few complaints can damage your reputation. For email campaigns, a safe spam complaint rate is 0.3% or lower. If your rate is higher, email providers will trust you less. They might block your emails.

Similarly, many spam complaints suggest a problem. Perhaps your audience is not engaged. Or, your emails go to people who did not ask for them. This also highlights the need for better list quality. You can use these insights to improve your verification process. You might need to verify new leads in real-time. You might also need to re-verify older parts of your list.

Next, use a re-engagement email campaign. Send a series of emails. Say you noticed their absence. Offer things like discounts. Or special content. You can also show value they missed. Always make it easy to opt-out. Make your re-engagement content personal. Use their name. Talk about past items they saw. Make offers based on what they like. Try different subject lines.

A soft bounce means your email failed for a short time. The person's inbox might be full. Their server could be down. Or your email might be too big. The email might still get there later. You can try sending the email again. Many soft bounces can still hurt your reputation.

Strategies for Handling Various Bounce Codes

Email servers send back codes. They do this when an email bounces. These codes tell you why it failed. You should pay attention to these codes. They help you fix problems.

For hard bounces, you must act fast. If you see a code like "550 User unknown," remove that email address. Do not send to it again. Keeping hard bounces on your list tells email providers you have a bad list. This can make your emails go to spam.

For soft bounces, you have more choices. If an inbox is full, you can try sending the email again later. If the server is down for a bit, wait and try again. You should watch soft bounces. If an email always soft bounces, you might need to remove it. This keeps your list healthy. Knowing these codes helps you keep good deliverability.
