The overwhelming consensus is that dedicated IP addresses are generally unsuitable for low-volume email senders. A minimum sending volume of around 50,000 emails per month is widely recommended to justify a dedicated IP and maintain a positive sender reputation. Some sources suggest even higher volumes (100,000-200,000) for optimal reputation building. Low-volume senders face challenges in building and maintaining a positive reputation, which is crucial for deliverability, and they may struggle to effectively warm up the IP. For these senders, leveraging shared IPs is usually recommended to benefit from the collective reputation of multiple senders. While some exceptions might exist if the emails are wanted, metrics are strong, and the sender has a solid warming plan, the risks usually outweigh the benefits for low-volume scenarios.
