If someone subscribes to shopify newsletter I got a doube double opt-in. One from Shopify and one from Klaviyo.

When I am disable Shopify double opt-in then It shows me on the costumer as marked that he/she subscribed to the newsletter.

When I disable Klaviyo double opt-in then I have two lists with Klaviyo Newsletter and Shopify Newsletter. But I want one flow for both Newsletter. If someone subscribeds to Shopify-Newsletter and Klaviyo-Newsletter then he or she has “longer” discount.

Because if someone subscribes to the Newsletter, I give him/her free shipping.

Hi @Christoph E., welcome to the community! 

If you’re confident that all Shopify captured emails should go into the same List to trigger the same Flow, then you can set the same List in the Shopify Integration settings in Klaviyo.

From the Klaviyo admin sidebar, go to Integrations → Shopify.

Then select that List in the dropdown where you want emails from Shopify to go into. 

Here’s some documentation for you to reference too:
