An autoresponder is a type of email that is automatically sent to a prospect when they perform a specific action, such as filling out a form, downloading a file, or registering for an event. To send an autoresponder, a marketer must create an email template using the classic email builder in Marketing Cloud Account Engagement. An email template is a reusable email design that can be customized with dynamic content and personalization. A test email, a one-to-one email, and a list email are not suitable for sending an autoresponder, as they are either not reusable, not automated, or not personalized.

The expected behavior if an automation rule is not set to repeat is that the prospect matches the criteria once and the action runs once. An automation rule is a rule that runs in the background and matches prospects based on certain criteria and performs certain actions. An automation rule can be set to repeat or not repeat, depending on whether the administrator wants the rule to run multiple times or only once on the same prospect. If the automation rule is not set to repeat, it means that the rule will only run once on each prospect who matches the criteria, and it will not run again even if the prospect matches the criteria again in the future. The other options are not the expected behavior if an automation rule is not set to repeat. The prospect cannot match the criteria multiple times and the action runs each time, as this would require the rule to be set to repeat. The action cannot run only once per day on the prospect, as this would require the rule to have a daily frequency limit. The prospect cannot match the criteria once, but the action runs multiple times, as this would require the rule to have multiple actions or a recurring action. Reference [Automation Rules Overview]

According to the Engagement Studio FAQ, when a program is paused, the prospects in the program are also paused and their wait times are not affected. Therefore, when the program is restarted, the prospects resume from where they left off. In this case, the prospect was on day 3 of a 5-day wait time when the program was paused, so they will be on day 3 when the program is restarted.
