Hello @HeidiK84 ,
A welcome email is a singular automation that sends to new additions from sign up forms for the list(s) specified (or all if so selected). If you're wanting additional steps after your initial email, I'd suggest creating an automation series to host your automated welcome email and timed follow-up emails.
If you'd like additional guidance, you may wish to call our general support so you can speak with an automation-specialized agent for live, 1:1 assistance and troubleshooting.
