I have a “coming soon” password protected page on my Shopify storefront and have an email subscriber opt-in for the past year that has collected over a hundred emails. They went to my Shopify account email. I am now ready to send them a newsletter through Klaviyo so I imported the list from Shopify, created the welcome series email and set it to live. But the welcome series is not sending to the imported Newsletter list. I tried to trigger a flow by setting a filter to send the flow to anyone added to the list in the past 30 days. Still nothing. I manually added my email to the newsletter list and I immediately got the first email of the welcome series. So I know it is only sending to those who were added to the list after the welcome series flow was created and set to live.
Please let me know how I trigger the welcome series flow to my existing list. Should I create a new list and import these accounts over again to trigger a flow?
