I have the default flow “Email Welcome Series with Discount” setup and a customer got a discount code from the welcome email but isn't subscribed to the newsletter, which is the trigger for that email being sent. Why would this have happened?

Hey @ryanmrt 

Welcome to the community!

This is definitely unexpected behavior as we have strict guidelines in place to not email customers who have not actually subscribed to your marketing. Although they did not subscribe, do they have a profile in your Klaviyo account? If so can you share a screen shot of their profile activity? It should show when the email we sent and any actions they took before/after receiving the email. It might be that they subscribed to the list to get the discount and then unsubscribed. Another idea if they don’t have a profile, is that someone who has subscribed to your list forwarded the discount code to them for use. 

Let me know how else I can help!

I’m having this same problem.  A customer used 2 separate coupon codes for 2 separate orders on the same day.  I checked where the codes came from, and they’re from my uploaded Newsletter Signup codes, but when I checked his profile, he never signed up for the Newsletter.  How did this person get access to my coupon codes?
