Do I need to "Warm up" my email domain?

  • August 1, 2023

Recently read through the email warming up guide, but still uncertain on what I should do. I have a very new domain I purchased less than a month ago, and just got my google workspace setup yesterday for gmail. Am I clear to start having Klaviyo send out welcome emails for me through my domain, or should I wait? I definitely don’t want to damage my email strength (not sure exactly how it works). New business and will not have insane email volume.

      Hello @mattisrighteous,

      Welcome to the Klaviyo and the Community!

      So glad to hear you’re taking your sending reputation and domain health so seriously. Since it sounds like you have a “cold” (brand-new) domain that’s never sent emails, warming would be the right process. 

      I recommend following the steps in our How to ramp and warm your sending infrastructure Help Center article to understand how to properly warm your domain. Warming can be broken down into 5-steps:

      1. Migrate historic engagement data
      2. Create engaged segments for sending campaigns
      3. Send campaigns to engaged segments
      4. Turn on high engagement flow emails
      5. Monitor your performance

      Overall, it wouldn’t be a concern to send emails from your domain. In fact, it’s recommended you do so to start building your reputation with inbox providers. But it is important to take a caution approach and start of slow. Because of this we always recommend sending campaigns to only your highly engaged subscribers for a period of time before slowly expanding into your 60, 90, 120, and 180 day engaged segments. 

      Turning on highly engaged flows such as a welcome series is recommended. What better way to build your reputation that responding to an action someone on your website takes (subscribing to your website). 

      I hope this helps!

          Good question @mattisrighteous . @David To has already answered it well in detail.

          Definitely warmup is required to establish a good reputation provided you follow the strategic warmup process properly. 

          However, a good domain strategy is the right starting point but warming up a completely brand new domain (recently bought) could be riskier and process may become lengthier. That’s why website’s subdomain is preferred and recommended.

          Also, what’s the email volume you’re planning to achieve during a warmup phase and then ramp up phase?

          Regards,

          Great question!
          Yes, warming up your email domain is highly recommended, especially if you're planning to send cold emails or bulk outreach. When a domain is new—or hasn't been used for consistent emailing—suddenly sending many emails can trigger spam filters or hurt your sender reputation.

          Warming up means gradually increasing the number of emails you send over a few weeks, while engaging with real recipients. This helps email providers like Gmail or Outlook see your domain as trustworthy and legitimate.

          So, in short:
          ✅ Yes, it's important.
          It protects your deliverability, ensures more of your emails land in inboxes (not spam), and builds a solid sender reputation.
