A dedicated IP address is an IP address that is used exclusively by one email account. This means that the IP address is not shared with any other account, which can help to improve deliverability. When an IP address is shared by multiple accounts, it can be more likely to trigger spam filters. Dedicated IP addresses can be particularly helpful for businesses that rely heavily on email marketing, as they can help to ensure that messages are delivered to the inbox. Dedicated IP addresses can also be used to create a custom domain for email, which can add an additional layer of professionalism. While dedicated IP addresses come with some benefits, they can also be more expensive than shared IP addresses. As a result, businesses should weigh the costs and benefits of using a dedicated IP address before making a decision.
