Klaviyo and Privy.

Privy builds pop ups and sign up forms that can send new subscribers to Klaviyo, where they start a welcome flow. The connection and the fields it passes depend on your setup, so confirm the current steps in the Privy documentation. The main jobs are sending people to the right list with clear consent and avoiding a second form tool doing the same thing.

What Privy sends to Klaviyo.

• Form submission. Someone completed a Privy form, which adds or updates a profile in Klaviyo when connected.
• Email and phone capture. The contact details collected, which need consent wording that matches how you will use them.
• Custom fields. Extra answers such as preferences, passed through only where the connection maps them.
• Form source. Which form or campaign the person came from, useful for tailoring the welcome message.
• Discount code delivery. Where a code is offered, how it is issued, which varies by setup and should match what the email says.

Flows it enables.

• Welcome series

  Starts when a Privy form adds someone to a list. Deliver any promised offer first, then introduce the brand.

• Preference based follow up

  Uses an answer from a form to send relevant products rather than a generic message.

• Back in stock or product interest

  If a form captures interest in a product, a follow up when it becomes relevant.

• Re engagement of new sign ups

  Nudges people who joined but never opened the welcome email, with a single gentle reminder.

Setup order.

1. 1. Check the documented connection

   Read the current Privy documentation to see how it sends subscribers to Klaviyo.

2. 2. Choose the target list

   Create or pick the list the form should feed, and name it clearly.

3. 3. Write clear consent wording

   Make sure the form text matches how you will email the person.

4. 4. Test a submission

   Submit the form with a test address and confirm the profile, list and fields in Klaviyo.

5. 5. Build the welcome flow

   Trigger it from the list and check the offer, if any, arrives as promised.

6. 6. Retire duplicate forms

   Turn off other capture tools that add the same people so profiles stay clean.

Common pitfalls.

• Two form tools adding the same subscriber with different consent.
• An offer in the form that the email does not honour.
• Missing fields because the connection does not map them.
• Pop ups showing to existing subscribers.
• Vague consent text on the form.

Apps and Klaviyo both change their screens and options over time, so confirm names against what you see and check each app's own documentation for current details.
