I’ve set up up my welcome message, changed the double opt-it to single opt-in, and tried to run a test with an email account. I clicked the confirmation email when it arrived and received the message that I was subscribed, and can see my email address in the list for the newsletter subscribers on my Klaviyo page but after 28 minutes still have not received the welcome email. I have customers who signed up for the email as far back as December and it turns out they haven’t received their welcome emails with the discount code either! Help! How do I get this to work and send the welcome email to those customers who’ve not received it yet instead of resending it to all newsletter subscribers?
TIA
