How to Connect OptinMonster with Klaviyo

OptinMonster offers seamless integration with Klaviyo email marketing service. Connecting OptinMonster to your Klaviyo email list is very easy.

In this article, you’ll learn how to connect Klaviyo with OptinMonster.

Before you start, as a best practice we recommend you also connect your campaigns to Monster Leads as a backup.

Connect Klaviyo

When you create a campaign in OptinMonster that you intend to collect leads with you’ll want to integrate with one or more services to send those leads to.

To send leads to Klaviyo, follow these steps:

1. Before you start, you’ll need a Klaviyo API Key. You can generate and copy an API Key from your Klaviyo account following this guide.
2. Navigate to the Integrations view in the campaign builder, search for and select Klaviyo.
   
3. Enter a Klaviyo Account Name (*internal use only) and your Klaviyo API Key in the appropriate fields, then select the Connect to Klaviyo button.
   
   *The Klaviyo Account Name can be anything that helps you identify the specific integration within OptinMonster. It’s possible to add more than one Klaviyo integration to your account and this is an easy way to differentiate between them when assigning integrations to individual campaigns.
4. Required: Once the Klaviyo integration has been connected select the Klaviyo List you wish to send leads to from the Email Provider Lists field.
   
5. When you’re finished, Save your campaign.

Add Extra Fields

Field Mapping

Get started using Field Mapping with Klaviyo.

Before you begin using Field Mapping with Klaviyo, please consider the following:

• Custom fields are referred to as Custom Properties in your Klaviyo account.
• Custom fields must be manually created in your Klaviyo account before they can be mapped to in OptinMonster.
• The following custom fields are reserved in Klaviyo and cannot be mapped to:
  • email
  • lead_source
  • ip_address
  • referrer
  • $consent
  • $first_name
  • $last_name
  • $phone_number (use the Phone field to send data to this custom field)
  • coupon_code (the Coupon Code won when creating a Gamified spin-to-win campaign)
  • coupon_label (the Coupon Label when creating a Gamified spin-to-win campaign)
• Custom field names should only contain letters, numbers, and underscores.
• You can manage your custom fields in Klaviyo following this guide.

Email Automations

To send emails automatically to new leads you’ll want to configure email automations within your Klaviyo account.

The following guides from Klaviyo may be helpful to get started:

• Getting started with flows
• How to create an email welcome series

Testing

We strongly recommend you test the optin form before publishing your campaign to ensure it is working as you expect.

Before you begin, please be aware of the following details when testing Klaviyo integrations:

• Previously submitted or already subscribed leads may be treated differently by Klaviyo than new leads. For this reason, we recommend using a completely unique email address each time you test submit your campaign’s form. You can use a free tool like TempMail.io or learn how to create unlimited unique email addresses from a single Gmail account.
• If the lead is captured in Klaviyo but you do not receive any automated emails it indicates the integration from OptinMonster to Klaviyo is correct, and the issue is with the automated email configuration. Klaviyo controls email automation exclusively. If you require assistance in troubleshooting email automations we recommend reaching out to Klaviyo support directly.

Get started testing with the Live Site Inspector tool.

Spin-a-Wheel Support

If you are configuring a Gamified spin-to-win campaign, spin-a-wheel support is automatically enabled when using our native Klaviyo integration. The Coupon Label and Coupon Code will be passed as custom fields with each lead.
