Overview
Connect Klaviyo to MNTN to sync your Klaviyo audiences to Connected TV (CTV) and coordinate follow-up email and SMS campaigns after CTV ad exposure.
Use your Klaviyo Lists and Segments for audience targeting and exclusion in MNTN, and use attributed ad impression events in Klaviyo to inform follow-up email and SMS campaigns.
How data moves
What Syncs | Direction | Available In |
Lists & Segments
| Klaviyo → MNTN | CRM Audiences for Targeting & Exclusion |
Ad Impression Events | MNTN → Klaviyo | Profile Activity Feed |
The Klaviyo integration supports two data flows:
Klaviyo to MNTN
MNTN automatically syncs your Klaviyo Lists and Segments each day. After they sync, your Lists and Segments are available as CRM audiences that you can use for campaign targeting or exclusion.
MNTN to Klaviyo
For Lists and Segments with Klaviyo attribution enabled, MNTN sends attributed ad impression events to matching Klaviyo profiles. These events appear in each profile's activity feed.
Each event type includes:
Ad Type
Campaign Name
Creative Name
Impression Timestamp
Why it matters
Why it matters
Use this integration to:
Reach your Klaviyo audiences on CTV. Use the same Klaviyo Lists and Segments for Connected TV (CTV) campaigns that you already use for email and SMS.
Coordinate email and SMS campaigns. Attributed events are sent to matching Klaviyo profiles, making it easier to follow up after CTV ad exposure.
Keep audiences up to date automatically. Your Klaviyo Lists and Segments sync with MNTN each day, with no manual exports or uploads.
Focus prospecting on new customer acquisition. Exclude existing customers using your synced Klaviyo audiences so your prospecting campaigns can focus on reaching new customers.
How it works
How it works
When you connect your Klaviyo account to MNTN, MNTN syncs your selected Klaviyo Lists and Segments each day.
Klaviyo supports two audience types:
Lists are managed manually.
Segments update automatically based on rules.
MNTN supports both audience types.
For Lists and Segments with Klaviyo attribution enabled, MNTN also sends attributed ad impression events to matching Klaviyo profiles. These events appear in each profile's activity feed, where they can be used to inform follow-up email and SMS campaigns.
After your audiences sync, you can:
Target a Klaviyo List or Segment in a campaign.
Exclude a Klaviyo List or Segment from a campaign.
Combine Klaviyo audiences with other CRM audiences.
Klaviyo audiences behave like other CRM audiences in MNTN. For more information, see Source Audiences with CRM.
Before You Begin
To use this integration, you need:
An active Klaviyo account.
At least one Klaviyo List or Segment that you want to use in MNTN.
Admin access to your Klaviyo account so you can authorize the connection and grant the required permissions.
Set It Up
In MNTN:
Sign in to your MNTN account.
From the account menu in the top right, select Integrations.
Find Klaviyo, then click Connect.
Choose whether to Allow attribution.
💡 Pro Tip: Allow Klaviyo Attribution is selected by default. Keeping this option selected allows MNTN to send ad impression events to Klaviyo later. Selecting this option doesn't enable attribution by itself.
Click Connect.
You're redirected to Klaviyo.
In Klaviyo:
Sign in to Klaviyo.
Click Allow to authorize the connection.
You're redirected back to MNTN.
Back in MNTN:
Select the Segments you want to sync.
💡 Pro Tip: We recommend syncing Segments when possible so your audiences stay up to date automatically.
Sync every List or Segment that you plan to use in MNTN, including audiences that you'll use for targeting or exclusion and any that you'll enable for Klaviyo attribution later. You can enable Klaviyo attribution after setup.
Click Next.
Select the Lists you want to sync.
Click Save.
⚠️ Warning: You must select at least one List or Segment to complete setup. You can sync multiple Lists and Segments.
After setup is complete, MNTN begins syncing your selected Lists and Segments. You can start a manual sync from the Manage page up to once every 30 minutes.
Enable Klaviyo Attribution
To send MNTN ad impression events to Klaviyo, you must enable Klaviyo attribution for each synced List or Segment that you want to measure.
Your MNTN campaign does not need to target a synced Klaviyo List or Segment for attribution to work. After you enable Klaviyo attribution for a synced List or Segment, MNTN can send ad impression events for matching customer profiles reached by your ads, including customers reached through other MNTN audience types.
In MNTN, click the AUDIENCES tab.
Click Segments > CRM.
Find the Klaviyo List or Segment that you want to use for attribution.
To filter the list, select Source, then choose Klaviyo.
📝 Note: The Type column identifies how each audience can be used in MNTN. Klaviyo Lists and Segments are imported as CRM audiences.
In Retargeting campaigns, CRM audiences can only be used for exclusion. For more information about how CRM audiences behave across campaign strategies, see Source Audiences with CRM.
Toggle Klaviyo Attribution ON.
MNTN begins sending ad impression events for matching customer profiles after attribution is enabled. Events appear in Klaviyo the following morning.
You can view MNTN ad impression events in each matching customer's profile activity feed. Customers with MNTN ad impressions also appear in the Klaviyo segment
mntn_saw_ad.
Manage Synced Lists and Segments
After you connect Klaviyo, you can update which Lists and Segments sync to MNTN at any time.
In MNTN, go to My Account > Integrations.
Find Klaviyo, then click Manage.
The Manage page displays your current synced Lists and Segments using the same Lists and Segments tabs that you used during setup.
Select the Lists or Segments tab.
Select or deselect the Lists and Segments you want to sync.
Click Save.
Disconnect It
Disconnecting Klaviyo stops MNTN from syncing your Klaviyo Lists and Segments and sending ad impression events to Klaviyo.
You can disconnect the integration from either platform.

In MNTN, go to My Account > Integrations.
Find Klaviyo, then click Manage.
Click Disconnect Klaviyo.
