If you’re working on cold email, buying domains, and sending out emails to your ideal customers then you’ve heard the phrase “be sure to warm up your domain!”. 

But what does that mean? What do you do? How do you do it? Don’t worry, in this article we go over the step by step process for warming up your domain, what it means, how to do it, why to do it, and everything in between. Let’s get started! 

What Does it Mean to Warm Up a Domain?

The phrase “warming up” is making sure your email/domain is seen as “being used” by Google. For example, let’s say you buy a domain and an email and start blasting out hundreds of emails a day on day 1. What is Google going to think? Obviously, you’re a scammer. We need to avoid Google thinking that because they will ‘blacklist’ your domain and you’d waste your money on that domain. So, we must do everything in our power to avoid that from happening.

In this article, we’ll talk specifically about warming up the domain. Think of “warm up” as an actual “warm up” for your workouts. You’re warming up your body before the hard core exercises, you’re preparing your body for what you’re going to endure. In reality, warming up is sending emails back and forth with other people during a period of time in small increments to let Google know you’re an actual user and not spam or a robot.

A common way to warm your emails are by sending 3-5 emails a day, either manually or through a software, for a period of two weeks and ramping up the count towards the end. This period is to let Google know you’re an actual user and not a robot. 

Software to Schedule Email Warm Up

If you’ve read our other article about cold email 101, then you’d be familiar with Instantly, a cold email sending platform. This is a software we highly recommend as it’s super easy to use and has tons of features and is constantly being updated and worked on. You’re going to want to sign up for this software as warming up your domain is one of their core features. Typically, other cold email sending softwares you have to pay per email to warm up, but instantly is unlimited warm up for unlimited domains you have registered with them.

This picture above is Once you sign up, you’ll see the image below - of course when you connect your email to Instantly so I’m assuming you’ve done this step already.

You see that Flame Icon that is green? That is the Instantly warm up feature. For you it won’t be green, but once you select it, it will walk you through the setup process and tell you the steps you need to take. 

Once that is turned on, your emails will begin to be warmed up and be a part of their engagement group and you’ll be set! I recommend waiting two weeks before sending out tons of emails as your domain will be primed and ready to go after two weeks.
