Why Are Both Shopify and Klaviyo Sending Confirmation Emails for Double Opt-In?

@janinnero - Here’s what I recommend if I understand you correctly.  Remember, Double Opt-in rules in Klaviyo are set on each LIST.  For example you can have List A have Double Opt-in Enabled, and List B have Double Opt-in Disabled.  

• Emails that come from Shopify, where Shopify has Double Opt-in Enabled, goes to a Klaviyo List where Double Opt-in is Disabled.
• Emails that come directly into Klaviyo (e.g. Klaviyo Signup Forms, 3rd Party Email Captures, etc) should be pointed to a DIFFERENT List where Double Opt-in is Enabled in Klaviyo.

In this way, Emails from Shopify only get the Shopify Double Opt-in.  And, Emails that go directly into Klaviyo, is directed to a DIFFERENT List that has Double Opt-in Enabled.

The only caveat, you have to build a Segment that includes profiles from both List as your “Marketing Segment” to combine both Lists.  Or, send a Campaign to each separately (which has the bonus of seeing the analytics unique to each List).

@drainyoo - I think Klaviyo doesn’t try to make assumptions on how you want to organize your Lists and what requirements might be stipulated - as in the case above, you may want to have Klaviyo have Double Opt-in or Not depending on your circumstances.  It’s a fair point, but I prefer that they allow me to choose then to make assumptions that might be false.
