How To Warm Up a Domain Before Email Outreach — RC-Educate

Hi guys, my name is Julia and today I’m going to tell you how to warm up a domain before email outreach.

Why should you even bother to warm up your domain in the first place?

Well, first and foremost, without adequate warm-up you risk burning your domain.

When this happens, your emails will stop getting delivered and any other email addresses on your domain will be affected.

Warming up a domain takes much longer than warming up an email address.

The warm-up stage before you begin sending cold emails should take a minimum of 3 months.

Why so long?

Well, every domain has its own reputation.

Domain reputation is earned over time.

It doesn’t just happen automatically.

It can be affected by many factors, one of which is the age of the domain.

Every new domain is treated as suspicious.

When a domain is younger than a month, spam filters mark it as suspicious by default — which means the messages sent from it are also flagged as suspicious.

Always better to be safe than sorry, so if you have a freshly set up domain, make sure you wait for 3 months before starting your outreach.

This time is necessary to build up a good reputation for your domain.

There are a couple of things, though, that may prolong or even disturb the warming up process.

Firstly, a suspicious frequency of email sending, for instance sending 100 messages on the first day.

Secondly, a low-quality list resulting in many bounced emails.

So in order to keep a good sending reputation, avoid sending large campaigns to untargeted prospects with numerous follow-ups.

Another important thing to remember is to make sure that your new domain is in line with the name of your main one so that no one gets confused when they get your message.

For this reason we set up as a domain from which we send cold emails.

But it also refers to our main domain —, so an example email address for outreach could be

Now that we’ve covered how long your domain warm-up should last, and how you can improve its reputation, let’s move to the core of this lesson, so how to actually warm up your domain for email outreach.

One way to do this is using an automatic warm-up.

After you’ve plugged in a mailbox on a newly set up domain, choose the domain warm-up, and the process will be done for you automatically.

You don’t need to set up the sending frequency or the right number of emails to be sent.

It’s easy as a pie and available to all premium subscribers at no additional cost.

The other way is to do the warm-up manually. To warm up your domain the manual way, follow this scenario:

Step 1 Buy a domain, unless you already have one.

Don’t set up email accounts on a fresh domain yet, though.

Wait a month before you add the first ones.

Step 2 is to configure your domain.

Firstly, you should take care of the mail exchange record which is used to gather replies.

Following this, set up the SPF & DKIM records, as these are crucial for sending and receiving emails.

Step 3 is to set up from 1 to 3 email accounts on the domain. Step 4 — configure the email accounts.

Set up the from line and a signature for each of them.

Step 5 is to send a handful of emails manually, but start no sooner than in the second month after registering your domain.

Remember to start with a couple of emails per day and send them to email addresses you know, such as your own, your friends’ and family’s or colleagues who will gladly reply back.

Getting replies matters to email providers, especially to Gmail.

It’s important to keep the sending natural — the frequency, volume and content of emails sent and received.

The final step of how to warm up a domain before email outreach is to prepare a test campaign in Woodpecker.

So log in and send your first automated email campaign.

You need up to 20 email addresses that you trust will not bounce, are real and can get you replies.

Ideally they will belong to your friends or colleagues.

And that’s it!

To sum up, a domain needs some time to get ready for outbound email campaigns.

Don’t rush the process because it can disturb the warm-up.

Don’t send massive campaigns from the very start, and don’t set up more than 3 email addresses on a new domain at the beginning.

Remember that when you send massive campaigns, even if your domain exists for a long time and has a good reputation, it may burn your domain.

Just don’t take it too fast and you should be alright.
