Summary
Maintaining a dedicated IP reputation for email sending requires a multifaceted approach that balances technical configuration, proactive monitoring, and adherence to best practices. Warming up new IPs with a gradual increase in email volume to engaged users is essential. Robust email authentication (SPF, DKIM, DMARC), consistent sending volume and frequency, positive engagement metrics, and regular list hygiene are key. Actively monitoring IP reputation via tools like Google Postmaster Tools, managing blocklist entries, and using feedback loops are crucial for detecting and addressing issues. Furthermore, the quality of the IP space, managing affiliate traffic, and segmenting your email lists to provide relevant content enhance sender reputation. Consider IP reputation's decreased weight and choose shared IPs for smaller senders. Understand ISP reactions through historical trends and focus on quality content to build trust with filters.
