Klaviyo's default lists and segments reference

Last updated at:

You will learn

Learn about the default lists and segments provided for all new Klaviyo accounts. Once you complete the Klaviyo setup wizard, you will have several default lists and segments populated in your account. These lists and segments identify key groups of people within your account and are designed to help you get off on the right foot with your sending strategy. The pre-populated lists and segments are as follows:

  • Preview List
  • Unengaged 
  • New Subscribers
  • Engaged 
  • Newsletter

When you add an integration to your Klaviyo account, a series of default ecommerce segments are also populated in your account.

Preview list

Your preview list is a static list of people that receive your test campaigns. This list should include yourself, as well as any other members of your organization who wish to receive previews of campaigns. Sending to this list will allow you to test the layout of your content in the inbox in a live send rather than a preview email sent from within the email editor. This can be particularly helpful if you want to check that your email is mobile-optimized, clips in Gmail, and more.


Your unengaged segment includes contacts who had several opportunities to engage with your brand, but haven’t. You may see 2 unengaged segments: Unengaged (3 months) and Unengaged (1 year). Depending on when your Klaviyo account was configured, these segments may not be available by default, but you can still create a new segment with the definition below in your own account.

If your campaign open rates are between 10-20%, exclude this segment from your future campaign sends.

New subscribers

New subscribers are contacts who subscribed to your newsletter list in the last 2 weeks. If you've recently integrated your ecommerce platform or uploaded a CSV file of contacts to your newsletter list in the past two weeks, these people will be included in this segment. Once someone has been on your newsletter list for longer than two weeks, they will filter out of this segment. There is also a condition in this segment that excludes anyone who is suppressed. While it's not possible to email suppressed contacts in Klaviyo, excluding them from a segment gives you a more accurate calculation of how many people within that segment you can email.

A new subscribers segment

There are several reasons you may want to use this segment. First, if you integrate your Klaviyo account with Facebook, you can sync this segment to Custom Audiences to target new subscribers.

Second, if you have a welcome series flow, you may want to exclude new subscribers from your campaign sends until they finish going through the flow to ensure that you're not sending mixed messages.

Last, this is a good group to keep an eye on from a business intelligence standpoint. You may want to monitor how this number of people changes over time to ensure that your number of recent signups is growing.


Your engaged segment is the primary group of people that you should send to. This segment includes people who have opened or clicked an email at least once recently. Some accounts have a single engaged segment: Engaged (3 months). Others may also have 30- and 60-day engaged segments. These segments will be empty until you send your first email with Klaviyo.

With the release of iOS15, macOS Monterey, iPadOS15, and WatchOS 8, Apple Mail Privacy Protection (MPP) changed the way that we receive open rate data on your emails by prefetching our tracking pixel. With this change, it’s important to understand that open rates will be inflated.

If your campaign analytics show a large number of iOS openers, we suggest identifying these affected opens in your individual subscriber segments.

This is the default "main list" that Klaviyo creates in your account. This should be the list that all new subscribers are added to, whether they sign up via a signup form, by opting in at checkout, or subscribe via any other acquisition method that you use. Email this list whenever you're trying to reach a broad audience, but ensure that you exclude your 1-year and 3-month unengaged segments to ensure that your open rates are above 10%.

Ecommerce segments

Once you add a native ecommerce integration (such as Shopify, BigCommerce, WooCommerce, Magento 1, and Magento 2) to Klaviyo, the following segments are also added to your account:

  • Churn Risks
  • Potential Purchasers
  • VIP Customers
  • Winback Opportunities
  • Repeat Buyers

Churn risks

A churn risk segment includes anyone who has purchased from your store at least once but has since lapsed in engagement. This gives you insight into who may soon turn toward another brand completely. You will want to re-engage these profiles with campaigns that include targeted content and a discount or other incentive.

You may have a high churn risk if you have a large number of one-time purchasers, in which case you will want to focus your marketing efforts on retaining customers after their first purchase. Consider creating upsell and cross-sell flows to send after someone makes a purchase, guiding them in the direction of other products they may be interested in.

Potential purchasers

A potential purchaser segment includes anyone who engaged with your brand in the past month but has yet to make a purchase. This is a good segment to target with campaigns, ads, and forms as they are interested in your brand and may benefit from a gentle reminder to purchase.

VIP customers

A VIP customer is one who has purchased from your site recently, does so frequently, and has spent a lot of money on your brand. You can redefine this segment to match your business preferences and customers’ buying cycles, but the default options are shown below.

Winback opportunities

Your winback opportunities segment includes former customers who are not suppressed but who have not placed an order in an extended period of time. A best practice is to generate a winback flow to re-engage these individuals and remind them of the value of your brand.

A winback opportunities segment

Repeat buyers

A repeat buyer is someone who has purchased from your store multiple times and will likely do so again. They are a good audience to target with branded content as they are already interested and may need a nudge in the direction of another purchase.
