Connect Klaviyo and sync your SoundSeam audience

Use Klaviyo with SoundSeam when you want new fans and buyers to enter the email list and automations you already manage in Klaviyo.

Klaviyo is currently a beta integration. The connection, list selection, contact sync, and supported SoundSeam events are available, but labels and capabilities may continue to improve.

Before you connect

Make sure you have:

• A Klaviyo account you are allowed to authorize.
• At least one list created in Klaviyo.
• A clear choice for which list should receive SoundSeam contacts.
• Access to SoundSeam Settings.

SoundSeam can keep Mailchimp, Kit, and Klaviyo connections on file, but only one email app is active for audience delivery at a time.

Connect Klaviyo

1. Open Settings and select Emails.
2. Find Klaviyo under Email Apps.
3. Select Connect.
4. Approve the requested access on Klaviyo.
5. Return to SoundSeam.
6. Choose the Klaviyo list that should receive your audience.
7. Select Save.

After the list is saved, the Klaviyo card should show the selected list and the Setup status should say it is ready to collect emails. Saving a Klaviyo destination also makes that connection active.

What SoundSeam sends to Klaviyo

SoundSeam creates or updates eligible Klaviyo profiles using contact information captured through supported audience activity, including free downloads and checkouts. Profiles are attached to the Klaviyo list you selected.

Supported activity can also appear in Klaviyo as SoundSeam metrics:

• SoundSeam Free Download Claimed
• SoundSeam Free Checkout Completed
• SoundSeam Paid Checkout Completed
• SoundSeam Cart Abandoned
• SoundSeam Offer Accepted
• SoundSeam Exclusive Purchase Completed

An event appears only when SoundSeam has the required contact and activity data and that activity is eligible to sync. Connecting Klaviyo does not import unrelated contacts from your Klaviyo account into SoundSeam.

Sync contacts you already captured

After connecting or changing lists, use Sync your list in SoundSeam Settings to queue eligible existing contacts for the active provider.

The sync runs in the background. Select the button once and allow the queue to process instead of starting the same sync repeatedly. New eligible activity continues to deliver automatically while Klaviyo is active.

Verify the connection

Check these signals in SoundSeam:

• Setup says Klaviyo is ready.
• The Klaviyo card shows Active and displays the intended list.
• Sync says delivery is running normally, or is waiting for the first activity.
• The audience count reflects contacts SoundSeam has captured.

Then check Klaviyo:

1. Open the selected list and look for an eligible test contact.
2. Open that profile and confirm the expected SoundSeam properties.
3. Check Klaviyo metrics for the matching SoundSeam event.

Use a real test action, such as claiming a free download with consent, when you need to verify the full path.

Fix common problems

No lists appear

Create a list in Klaviyo first. Return to SoundSeam, refresh Settings, and reconnect if the list still does not load.

Klaviyo says Reconnect or Needs attention

Select Reconnect on the Klaviyo card and approve access again. Then confirm the destination list.

The wrong list is selected

Open the list selector on the Klaviyo card, choose the correct list, and select Save. SoundSeam queues eligible audience data for the newly active destination.

Contacts or events are missing

Confirm that Klaviyo is the active provider and that a list is selected. Use Sync your list once, then review the status for failed or queued work. Remember that a profile or event must be eligible and contain the data required by Klaviyo.

For deeper diagnosis, see Fix an email integration or contact sync.

If you switch email apps

Making Mailchimp or Kit active sends future SoundSeam audience delivery to that provider instead. Contacts and events already stored in Klaviyo remain subject to your Klaviyo account settings and retention rules.
