Consent and Klaviyo subscriptions

In many countries you need a shopper's permission before you send them marketing email. bluebarry lets you ask for it with a checkbox under the email question, keeps the answer on the shopper's profile and passes it on to Klaviyo as a marketing subscription.

How consent and Klaviyo work together

When Klaviyo is connected, every shopper who leaves an email address through bluebarry is sent to Klaviyo with their answers, whatever they chose. Consent decides one thing: whether bluebarry subscribes them to your email marketing. The Marketing subscription setting in Klaviyo settings sets the rule.

Email marketing status in Klaviyo per setting
Marketing subscriptionBox tickedBox not tickedNo consent box
AlwaysSubscribedNot subscribedSubscribed
Only if consentedSubscribedNot subscribedNot subscribed
NeverNot subscribedNot subscribedNot subscribed

If you sell to shoppers in the EU, Only if consented together with a consent checkbox is the safe choice. People who didn't opt in still arrive in Klaviyo, but as not subscribed, so they won't get your campaigns.

Add a consent checkbox to your quiz

  1. Open your quiz on the Design quiz tab and select the question that asks for the email address. Under Question settings, its display type is Email. A Phone question works the same way.
  2. Under Validation, switch on Ask consent. A checkbox appears below the input in the preview.
  3. Click the checkbox text in the preview and write your own, for example: "Yes, send me personal product tips and offers by email."
  4. To link your privacy policy, type @ in the text. Under Quiz links, click Create new link, fill in the Link title and Destination URL, and click Create link.
  5. Publish your quiz.

Popups can ask for consent too, with the Marketing consent field. That consent counts the same way.

Set Klaviyo to match

  1. Go to Integrations and click the settings icon on the Klaviyo card.
  2. Under Marketing subscription, choose Only if consented.
  3. Click Save changes.

Check consent in Profiles

Take your published quiz twice: once with the box ticked and once without. Then go to Audience → Profiles.

  • The Consent column shows Yes, No or Unknown (no checkbox was shown).
  • The Synced column shows whether the profile reached Klaviyo. Both test profiles should be synced.
  • In Klaviyo, the ticked profile shows as subscribed to email. The other one doesn't.

Good to know

  • Don't want bluebarry profiles in Klaviyo at all? Then don't connect Klaviyo, or disconnect it on the card. No setting keeps profiles out while Klaviyo is connected.
  • When you erase a shopper in bluebarry, Klaviyo keeps its own copy. Remove them in Klaviyo as well.
