For a marketing campaign, what method should be used to automate emails triggered by file placement on FTP?

Triggered Automation is the appropriate method for automating emails based on specific events, such as the placement of a file on an FTP server. This approach allows marketers to set up automated workflows that respond immediately to external triggers, ensuring that recipients receive timely and relevant communications as soon as the specified condition is met.

When a file is uploaded to an FTP, the Triggered Automation can be configured to monitor this event in real-time and automatically send out emails. This efficiency not only enhances the responsiveness of the marketing campaign but also allows for personalized communication tailored to the context of the file being placed.

In contrast, other methods like Scheduled Automation would send emails based on a predetermined schedule rather than in response to specific triggers. User Initiated Send is reliant on manual initiation by a user, making it unsuitable for automatically responding to file placements. Dynamic Content generally refers to the customization of content within emails based on recipient data, but it does not relate specifically to the activation or automation of sending emails based on external events.
