Understand how Klaviyo works with Crisp

Contact synchronization

When automatic synchronization is enabled, the Klaviyo plugin syncs Crisp contacts to Klaviyo whenever a contact is created or updated in Crisp. If automatic synchronization is disabled, operators can still manually sync a contact from the Klaviyo widget in Crisp.

Contact properties synced from Crisp to Klaviyo can include:

• First and last name → middle names are treated as last names
• Phone number
• Email address
• Contact address and location
• Job title
• Contact custom data → when enabled from the Klaviyo plugin settings in Crisp

Contact events

Events that happen in Crisp can be added to the Klaviyo profile. These events help marketing and support teams understand how a customer interacted with your team.

All events include these common properties:

• website_id → Crisp workspace ID
• session_id → conversation ID where the event occurred
• conversation_url → direct link to the Crisp conversation
• conversation_segments → segments associated with the conversation
• conversation_data → custom data associated with the conversation
• contact_address → contact address
• contact_ip_address → contact IP address
• contact_device_timezone → contact device timezone offset in UTC
• contact_device_locales → contact device locales, such as en_US or pt
• contact_device_user_agent → contact device user agent
• contact_device_os_name → contact device operating system name
• contact_device_os_version → contact device operating system version
• contact_device_browser_name → contact device browser name
• contact_device_browser_version → contact device browser version
• contact_device_city → contact device city
• contact_device_country → contact device country
• contact_device_region → contact device region

Supported Crisp events include:

• Conversation Opened → triggered when a conversation changes state to Unresolved or Pending
• Conversation Closed → triggered when a conversation changes from Unresolved or Pending to Resolved
• Conversation Subject Updated → triggered when an email conversation subject is set or changed; includes conversation_subject
• Conversation Rating → triggered when a user leaves a rating; includes rating and rating_comment

Widget data

The Klaviyo widget displays the customer's Klaviyo profile directly in Crisp. It can show profile details such as lists, segments, coupons, and events. Operators can also add or remove customers from lists when allowed by the plugin settings.

Email conversations

If you send an email campaign from Klaviyo, you can receive replies in Crisp by using your Crisp email address as the campaign reply-to address.

1. In Crisp, find your email address from Settings → Workspace Settings → Setup & Integrations → Email.
2. In Klaviyo, set that Crisp email address as the campaign reply-to address.
3. Send the campaign from Klaviyo.

All replies are delivered to your Crisp Inbox.

In the example below, @crisp.yourcompany.com is a custom email domain. You can also append a segment to the reply-to mailbox. For example, reply-to+june2024@crisp.yourcompany.com adds the june2024 segment to the Crisp conversation.

SMS conversations

Klaviyo SMS conversations can also be handled from Crisp. When a customer sends an SMS to your Klaviyo number, Crisp receives the message as a conversation. Operators can reply from either Crisp or Klaviyo, and the messages appear in the Crisp conversation.

Troubleshooting

I see SMS messages in Klaviyo but not in Crisp

Open Plugins → Klaviyo → Settings in Crisp and make sure the option to receive Klaviyo SMS messages in Crisp is enabled. If it is already enabled, reconnect the plugin and send a new SMS test message.
