IP Pools: All You Need to Know

IP pools are collections of dedicated IP addresses used to manage and protect the sending reputation of email streams, particularly differentiating between marketing and transactional emails to ensure high deliverability rates. By using separate IP pools, users can prevent marketing emails, which often face spam filters, from negatively impacting the reputation of transactional emails that require high engagement. Additionally, IP pools can segment recipients based on engagement levels, allowing for targeted improvement of deliverability rates without compromising the reputation among highly engaged recipients. While this strategy is beneficial for those with large email volumes and multiple IPs, excessive IP usage can appear suspicious to mailbox providers, potentially harming reputation. Twilio SendGrid recommends creating subusers for organizational purposes and offers resources for managing IP pools, boosting deliverability, and optimizing sending reputation.
