Sheela's Pottery is a legacy company, and they mostly stick to single emails to all their subscribers. Recently, they were hoping to branch out: which Mailchimp feature can you use to automate the sending of a welcome email series?

Customer Journeys allow you to automate a series of emails based on specific triggers, such as a new subscriber joining your audience. This feature is ideal for creating a welcome series that sends multiple emails over time. Merge tags are used to personalize email content, not to automate sending. Segments are used to group subscribers based on shared characteristics, which can then be targeted by campaigns, but they don't automate a series of emails themselves. Popup forms are used to capture new subscribers, but they don't manage the automated sending of a series of emails after signup.
