Warming up your IP is away to help you see what is working and what isn’t in an email plan before permanently tarnishing your IP’s web cred. A healthy IP receives good engagement and this is the aim with an IP warmup. To steadily increase email open rates, you can begin by sending small volumes of email and then progressing to larger volumes. Keep in mind the need to track engagement as well. This helps you make changes and fixes to optimize your emails before you send to them to a bulk of your users.
