When implementing this method, you first purchase a set of dedicated IP addresses. The number of IPs you need depends on your sending volume and frequency. As a general rule, you should use one IP address for every 5,000 to 10,000 emails you send per day . This ensures that each IP maintains a consistent sending volume, which is critical to building and maintaining a good reputation.
Set up multiple sending domains
These cannot be subdomains of your primary domain (e.g. email1.yourdomain.com, email2.yourdomain.com), but must be completely separate domains. Each domain should be properly authenticated using SPF, DKIM, and DMARC protocols. This authentication is email performance critical to building trust with Internet Service Providers (ISPs) and improving deliverability.
Implement a robust IP and domain warm-up process. This involves gradually increasing the volume of email sent from each new IP and domain over a period of several weeks . Start with a small amount and increase slowly, closely monitoring engagement metrics. This process fantuan database will help build a good sending history and reputation with the ISP.
Develop a rotation strategy for your IPs and domains
This may include using different IPs and domains for different types of campaigns, segmenting your lists and assigning specific IPs/domains to each segment, or implementing a round-robin approach where you rotate your IPs and domains with each send.
Implement a sophisticated email infrastructure to handle the complexities of best chatsonic alternatives in 2025 IP and domain rotation. This may involve using a premium email service provider or building a custom solution to manage rotation and track performance across multiple IPs and domains.
Carefully monitor the reputation and performance of each IP and domain . Use tools such as Google Postmaster Tools, Microsoft SNDS, and third-party reputation monitoring services to track sender reputation, spam complaints, and other key metrics for each IP and domain.
Implement a system to quickly identify
And isolate problematic IPs or domains. If an IP or domain starts to have singapore data delivery issues, you should be able to quickly remove it from rotation and investigate the cause without impacting your overall sending capabilities.
All IPs and domains. Look for patterns in open email performance rates, click-through rates, and spam complaints. Use this data to optimize your rotation strategy and identify IPs or domains that may need additional warm-up or deactivation.
Consider implementing IP and domain segmentation based on email type or recipient engagement. For example, use the best performing IPs and domains for your most engaged subscribers or for transactional emails that require high deliverability.
