Please note that this process and the numbers described below can also be applied to warming up your new domain alongside your private IP.

Purchased IPs are typically pre-warmed by Elastic Email which will dramatically help the warm up process, but your email is unique and it takes time to warm up your domain as well on a new IP.

We recommend warming up new private IP(s) over a 4 week period by gradually adding email volume to the new IP address(es).

It is important to warm up your IP(s) so you can build a good sending reputation and improve your chances of getting your email into your subscriber’s inboxes.

Warming up an IP address means that you start sending low volumes of email on your dedicated IP and then systematically increase your email volume over a period of time. This gives ISPs the opportunity to recognize, identify and evaluate your sending practices.

There’s no guarantee that you will not have some deliverability challenges at first, but using these best practices will help set you up for long-term success.

Given all of these needs, the IP warm up process should start small. When warming your IP(s), your sends might look something like this:

NOTE - The numbers above are based on sending new mail on ONE IP.

Elastic Email typically pre-warms purchased IP's.

If you are warming up a cold IP, we would suggest reducing these numbers by half.

When warming up an IP, it is always recommended to send to your most engaged contacts first. Our segmentation tool can help you achieve this.

You can organize your contacts using different segment rules, this will help determine the most recently engaged contacts for sending to. For further tips on increasing subscriber engagement and using segments please refer to the following articles:
