How to Build and Maintain a Strong Sender Reputation for Better Deliverability?

A strong sender reputation is key to inbox placement. With no2bounce, discover actionable steps to build, monitor, and protect your reputation.

What is Sender Reputation?

Sender reputation is a score assigned to your domain or IP address by Internet Service Providers (ISPs) and email service providers (ESPs). It determines whether your emails land in the inbox, spam folder, or get blocked entirely. A high sender reputation ensures better deliverability, while a poor reputation can cripple your email campaigns.

Factors That Impact Sender Reputation

Bounce Rates and Spam Complaints

High bounce rates and spam complaints are major red flags for ISPs. They indicate poor list hygiene and irrelevant content, which can lower your sender reputation.

Engagement Metrics (Opens, Clicks, Unsubscribes)

ISPs prioritize emails that recipients engage with. Low open and click rates, or high unsubscribe rates, signal that your emails are unwanted, hurting your reputation.

Domain and IP Health

Your domain and IP address must be free from blacklists and have a history of sending legitimate emails. Any association with spam or malicious activity can damage your reputation.

Best Practices to Improve Sender Reputation

Gradually Warm Up Your IP Address

If you’re using a new IP address, start by sending a small volume of emails and gradually increase it over time. This process, known as IP warm-up, helps build trust with ISPs.
