Link Airtable to Klaviyo using Zapier: Single opt-in still sends out confirmation emails?

I used Zapier to link new entries in an Airtable base to Klaviyo. The goal is to auto-subscribe these contacts to our newsletter list in Klaviyo.

 

In our newsletter list, ‘Single Opt-in’ has been selected for ages, yet our customers receive an email to confirm their subscription to the newsletter.

 

I have no clue how to stop these confirmations from popping up.

    Hi @Crodeon Team, welcome to the community!

    If you are using Zapier to link new entires from AirTable to Klaviyo, make sure it’s being added to the exact List that has the Single Opt-In configured (I assume this is your main Newsletter List). 

    If you are adding it to a different List, make sure that List is Single Optin configured - or - make sure to point it to the proper List.  

    See my quick example screenshot, double check it’s the right “List” in your Zapier settings:

    Check back and let us know if it worked!

     @retention I have confirmed that the list ID is the correct one.

    @retention Do you maybe have any other suggestions to fix this problem?

    Key is making sure that single opt-in is configured for the same list. Then, new contacts should not get the double-opt-in confirmation email.

    And if I can add a subtle pitch, we at Outfunnel also offer an Airtable-Klaviyo integration that allows easily syncing contacts, mapping fields and configuring subscribe status in the process.
