Hi. I'm new to Convertkit and am setting up a Welcome Newsletter sequence. I've already created a Welcome Newsletter to send out and also the sign-up forms for my website. I want the email to be sent immediately when they sign up. Following the 'Getting Started: Lunch and learn video series', it states you can select from email templates you have already set up. However, when I got to choose the Welcome newsletter that I have already created, there is no option to choose it. How do I link a form/welcome newsletter to the sign-up boxes? Does anyone know. Thank you.
