The decision to acquire more dedicated IPs hinges on a combination of factors, most notably email volume, reputation management, and infrastructure requirements. Experts and marketers agree that high-volume senders (generally exceeding 50,000-100,000 emails per month) benefit from dedicated IPs to control their reputation and avoid the negative impact of shared IP environments. Consistency in sending patterns, the types of mailbox providers (with Gmail being less sensitive), and infrastructure limitations (such as failover concerns) also play a significant role. However, experts caution against using dedicated IPs for low-volume sending, as they lack an established reputation and require careful warming up. Before adding IPs, it is important to understand the root cause of deliverability issues, such as rate limiting or content-related problems.
