Understanding Domain Reputation

Your domain reputation is the score mailbox providers assign to your sending domain based on your email practices. A strong reputation means higher inbox placement, better open rates, and greater engagement. Conversely, a poor reputation leads to bounces, blocks, and messages lost in spam folders.

Why Domain Reputation Matters for Deliverability

Every email you send impacts how ISPs and spam filters perceive your brand. A healthy reputation:

• Boosts inbox placement and reduces bounce rates
• Increases subscriber trust and engagement
• Protects your sender score and future campaigns

Key Factors That Influence Your Domain Reputation

• Bounce Rate: High bounce rates signal list hygiene issues.
• Spam Complaints: Too many “mark as spam” clicks will lower your score.
• Sending Frequency: Sudden spikes can trigger spam filters.
• Authentication: Proper SPF, DKIM, and DMARC setup earns trust.
• Engagement Metrics: Opens, clicks, and replies show relevance.

Best Practices to Boost Your Domain Reputation

1. Use a Reputable Email Verification Tool

   Regularly clean your list with Bouncer’s powerful verification platform to remove invalid, disposable, or toxic addresses before sending.

2. Segment and Engage

   Send targeted content to engaged subscribers. Segment by behavior and preferences to maintain low complaint rates.

3. Authenticate Your Domain

   Implement SPF, DKIM, and DMARC records so ISPs can verify your identity and trust your messages.

4. Monitor Feedback Loops

   Subscribe to ISP feedback loops to see who marks your emails as spam and promptly remove them.

5. Warm Up Your IP and Domain

   When starting new campaigns or using new infrastructure, increase send volume gradually to build positive history.
