Send audiences to Klaviyo

Klaviyo is an email platform for targeting, personalizing, measuring, and optimizing email and Facebook campaigns.


This destination uses the Klaviyo REST API .

Review the rate limits that are applied to endpoints in the Klaviyo REST API, specifically the endpoints that add profiles , create a list of profiles , and remove profiles , which are the endpoints Amperity uses to manage customer profiles.

Before sending a set of customer profiles to Klaviyo, and to help set expectations, you should review the rate limits and estimate the amount of time required to complete the process of adding your set of customer profiles to Klaviyo.

If you don’t want to wait to load customer profiles, you may instead use the SFTP import tool process. This approach is efficient and quick. It uses the built-in SFTP connector in Amperity and is capable of importing large sets of customer profiles much faster than a rate limited API.

The CSV file that is imported to Klaviyo has specific requirements on formatting and must include one (or more) of the following fields: “Email”, “PhoneNumber”, and/or “ExternalID”. When these fields are present in the CSV file they must have those exact names.

This topic describes the steps that are required to configure campaigns to send email address lists to Klaviyo.


Ask your DataGrid Operator or your Amperity representative for help configuring Klaviyo as a destination to which you can send campaigns for customer activation.

Build a segment

Use the Segment Editor to build any audience using a series of drop-downs and picklists.

As you define the attribute profile for an audience be sure to refresh segment insights to see how many customers match your audience and to see how much value they bring to your business.

When the segment is ready, activate it, and then use it use it in a campaign to send to your preferred destinations for customer activation.

Which attributes should you use?

You can use any attribute that is in your customer 360 database to define your audience.

When the list of customers who belong to this audience is sent to Klaviyo as part of a campaign you will be required to choose specific attributes to send.

Klaviyo supports the following attributes: email address lists.

Build a campaign

Use the campaign editor to build campaigns that send data to Klaviyo. Add a segment, define exclusions and sub-audiences, and then configure Amperity to send campaign data to Klaviyo.

To build a campaign

Step 1.

The campaign builder is available from the Campaigns page. The Create Campaign button in the top right corner of the page opens the campaign builder.

After the campaign builder opens, give your campaign a name.

Open the campaign builder and give your campaign a name.


The campaign name will always appear in the filename that is sent to any destination.

Use good naming patterns for the campaigns you will send to Klaviyo. Good naming patterns help ensure that you can easily find your campaigns within Amperity and that the campaign is discoverable in Klaviyo by users who may not be the same users who built the campaign in Amperity.

Avoid duplication between campaign and recipient group names.

Avoid using Klaviyo in the name unless the campaign is sent only to Klaviyo.

Use a naming pattern that ensures the campaign name works across every recipient group that is configured within any sub-audience.

If brand names and/or region names apply to all sub-audiences in the campaign, consider using them within the campaign name.

Step 2.

All campaigns start with an audience. Choose a segment from the Include drop-down list. The customers in that list will become the audience for this campaign.

Choose the audience to use with your campaign.


When a campaign starts with an audience that is defined by a single segment, you can use the segment insights for that segment as a way to measure the performance of that audience over time.

Step 3.

Sometimes campaigns need to exclude certain members of your audience. For example, a churn prevention campaign is often configured to exclude customers who have opted-out of SMS messaging and/or who have unsubscribed from an email list.

When you need to exclude audience members, choose one (or more) segments from the Exclude drop-down list. The customers in an exclusion list will be removed from the audience for this campaign.

Exclude some customers from this campaign.
Step 4.

Some campaigns have just one audience, while others have many and require sub-audiences.

Sub-audiences can be many things. How you choose to configure them depends on your audience, marketing strategy and goals, and the type of campaign you will run in Klaviyo.

Click Add recipient group to add another recipient group to a sub-audience. The total percentages for all recipient groups (and the control group, if present) must be 100%.

Click Add Sub-audience to add more sub-audiences to this campaign, and then use the Audience Builder to define the criteria for that sub-audience.

Step 4.

Assign Klaviyo as a destination for at least one recipient group, and then edit the attributes for the sub-audience to ensure Amperity is sending the right data to Klaviyo.

Step 4.

Click Edit attributes to review the attributes that Amperity will send to Klaviyo.

Klaviyo requires only email addresses. There are no optional fields.

Amperity pre-selects the list of attributes that may be sent to Klaviyo. The Edit attributes page for Klaviyo is similar to:

Edit the attributes for Klaviyo.


The Merged_Customers table is the default table from which data is sent to Klaviyo, even though segments are often built against the Customer360 table. This is by design. The Merged_Customers table is the underlying table for customer profile data and is the source for all customer profile data that exists within the Customer360 table.

Step 7.

A campaign can be configured to be sent once or on a recurring basis. A campaign can also be scheduled (i.e. “to be sent at the time you choose in the future”) or to be sent as soon as possible.

Give your campaign a name.
Step 8.

Enter the date on which you plan to launch your campaign in Klaviyo. This date helps Amperity improve results tracking and campaign results measurement.

Configure the schedule and timing for your campaign.
Step 9.

When your campaign is ready, click the Schedule button in the top right corner of the Campaigns page.


Amperity will begin processing the segments that define audiences, exclusions, and sub-audiences, and will then send the results to Klaviyo.

Please allow for enough time for Amperity to complete this process before starting a campaign in Klaviyo.
