How to integrate Privy with Klaviyo lists

Q: How do you link the accounts?

In Privy, open Settings (bottom left) > Linked Accounts . Under Available Integrations, choose Klaviyo . In Klaviyo, create an API key. Privy recommends granting full access for every API scope. Paste the key, click Link Account . Klaviyo should appear under Authorized Accounts.

Q: How do you sync a display?

The 2023 "Follow-up > Sync signups" button is now Settings on the display. Open Displays , pick the display. Go to Settings > Show Advanced Settings > Sync Integrations . Add Klaviyo, pick the list, save. Repeat per display. There is no account-wide "sync everything". Phone numbers must be E.164. Privy will add +1 for US and Canadian numbers. Every other country needs the code (+44 and so on). Privy adds the + if you omit it.

Privy still pushes Convert signups into Klaviyo. The 2023 path (Account > Integrations) is now Settings > Linked Accounts. Sync is one-way: Privy to Klaviyo, lists only, not segments. Vendor source: Sync Contacts to Klaviyo.

This is the right setup when Klaviyo sends and Privy captures. If Privy also sends, you do not need this. You would be paying two ESPs.

Frequently asked questions

Why did nothing land in my Klaviyo segment?

Segments are computed. Privy can only write to lists. Point the sync at a list, then build the segment in Klaviyo.

Can Klaviyo data flow back into Privy?

No. One-way.

Displays-only pricing if you keep Klaviyo as the ESP: Privy pricing.
