File Drop Entry Source is one of the most powerful automation triggers in Salesforce Marketing Cloud (SFMC). It allows marketers to automatically start an automation as soon as a file is uploaded to a specific SFTP folder. This makes it ideal for handling recurring data imports and real-time data updates without manual effort.
In this in-depth guide by Peoplewoo Skills, you’ll learn how the File Drop Entry Source works, how to configure it, and where it fits in your automation workflows with real-life examples.
What is File Drop Entry Source?
The File Drop Entry Source in Salesforce Marketing Cloud is an automation trigger that starts an automation automatically whenever a new file is placed in a specified folder on the Marketing Cloud SFTP server. Unlike Scheduled Automations, which run at predefined times, File Drop automations execute the moment the file arrives — ensuring near real-time data processing.
In simple terms, imagine you have an external CRM or e-commerce platform exporting daily customer data. Instead of manually running an import every day, you can use the File Drop Entry Source to detect the file upload and automatically start a workflow that updates your Data Extensions, cleans the data, and even triggers follow-up campaigns.

How to Configure File Drop Entry Source in SFMC

- Select your storage location:
- Enhanced FTP: The main SFTP storage in Marketing Cloud.
- Safehouse: A secure temporary storage area within SFMC for internal file use.

/Import/). - Define a File Pattern (e.g.,

Example Folder Structure for File Drop

Real-Life Example: Automated New Subscriber Import
Let’s consider a real-world scenario:
- Your website collects daily new signups and exports them as
new_subscribers_2025_11_05.csv. - This file is automatically uploaded to your Marketing Cloud SFTP “Import” folder.
- The File Drop Entry Source detects the file arrival and starts the automation immediately.
- Automation steps:
- Move and decrypt file using File Transfer Activity.
- Import subscribers into a Data Extension.
- Trigger a Welcome Journey in Journey Builder.
As a result, new subscribers instantly receive welcome emails without any manual effort — ensuring seamless engagement and faster onboarding.
