What does IP warming refer to?

IP warming refers to the practice of gradually increasing the volume of emails sent from a new IP address. This process is crucial for establishing a positive sender reputation with Internet Service Providers (ISPs). When a new IP sends a low volume of emails initially, it allows ISPs to monitor the engagement levels of recipients with those emails, such as open rates, click rates, and complaint rates. As the new IP builds its reputation through consistent sending and good engagement metrics, the volume of emails can be increased over time without risking deliverability issues.

The correct understanding of IP warming highlights its role in ensuring that the emails sent from the new IP address are recognized as legitimate and trusted by ISPs. Therefore, it is essential for organizations looking to maintain effective email communication with their audience.
