Hello,
My shopify store has the typical sign-up form, the form is linked with a Klaviyo newsletter list, and when new subscriber, Klaviyo sends a welcome mail with a discount coupon, up to here no rocket science.
The double opt-in is enabled in Shopify's notifications, however in Klaviyo's newsletter list don't.
The problem is since some time ago there are bots subscribing and catching coupons, How is possible if the double opt-in is enable?
Please, let me know if you had the same problem and how you fixed it.
Many thanks in advance,
Miguel
