You should carry out IP warming if you’re just starting out in email marketing, or you’re in the process of switching email providers. When you switch email providers, your emails contain a new IP address. IP warming is also recommended if you have a large subscriber list of more than 50,000 contacts.
IP warming is about the process of warming up your IP address so that it's deemed trustworthy to email inbox providers.
