When working in Salesforce Marketing Cloud (SFMC), managing files effectively is essential for ensuring smooth operations, optimizing performance, and maintaining compliance. Whether you're a developer automating content updates, an admin maintaining secure storage, a consultant designing scalable campaigns, or an architect defining the system landscape — file management plays a key role.
In this blog, we’ll explore the file management capabilities in SFMC, best practices, and how each persona can make the most of them.
1. Where Are Files Stored in SFMC?
A. Content Builder
Stores images, documents (PDFs, Excel, etc.), videos, and HTML files.
Used in emails, landing pages, and social posts.
Organized in folders for easy access.
Supports tagging and sharing with business units.
B. Enhanced FTP (Safehouse)
Secure storage space to upload/download files via FTP.
Used heavily for automated imports/exports, data extensions, and file drops.
Requires explicit access credentials and folder permissions.
C. SFTP in Automation Studio
Used in file-based automation flows.
Supports scheduled imports (e.g., .csv for contacts).
Automation activities like "File Transfer" and "Import File" rely on this.
D. External FTP (Customer-Hosted FTP/SFTP Servers)
In many cases, enterprises need to integrate SFMC with their own secure external FTP servers (SFTP/FTPS). This allows for:
Automated data exchange between internal systems and SFMC.
Third-party data providers (e.g., CRM, loyalty systems, POS) to drop data securely.
Complying with internal IT policies or local data regulations by not using the SFMC-provided Safehouse.
Supported Protocols:
SFTP (Secure File Transfer Protocol)
FTPS (FTP over SSL)
2. File Management Tools and Automation
A. File Transfer Activity
Moves files from the Safehouse to the Enhanced FTP folder or vice versa.
Decrypts, unzips, or converts files for automation usage.
B. Import File Activity
Used to import a file (e.g., .csv) into a data extension.
Can be chained with File Transfer activities in Automation Studio.
C. Export File Activity
Exports a data extension as a .csv, optionally encrypts and places it in the FTP folder.
D. Script-Based Management (SSJS/AMPscript)
Developers can use SSJS to interact with assets (e.g., read/write data, interact with Content Builder).
API calls (REST/SOAP) can be used to fetch assets, list files, or upload via backend.
3. Security & Access Control
Role-based access control ensures users only see what they need.
FTP folders can be segmented by business unit or function (inbound/outbound).
Best practices include:
Use multi-factor authentication (MFA) for FTP access.
Clean up old or unused files regularly.
Avoid sensitive data in public-facing file links.
4. APIs for File Management
REST API: Useful for managing assets in Content Builder (/asset/v1/content/assets).
SOAP API: Offers file upload/download support, particularly for legacy systems.
Use Cases:
Syncing files from a CMS to Content Builder.
Auditing image usage across templates.
Migrating files across BUs or sandboxes.
5. Best Practices by Role
For Developers:
Use REST API or SSJS for dynamic asset management.
Automate file checks before data import to avoid broken automations.
For Admins:
Audit the FTP and Content Builder regularly for outdated or unused files.
Enforce folder structure and naming conventions.
For Consultants:
Document file usage and maintenance guidelines in the implementation playbook.
Help clients map business needs to folder structures and access rules.
For Architects:
Design a multi-BU file governance model.
Define an FTP file lifecycle strategy: file drop, process, archive, cleanup.
6. Common Pitfalls & How to Avoid Them
Pitfall | Solution |
Files stuck in the Safehouse | Ensure File Transfer Activity is correctly configured |
Image links breaking in emails | Use published URLs from Content Builder |
Automation fails due to missing files | Add a file existence check before import |
Data exposed via file URLs | Always verify access permissions before sharing links |
7. Integrations & Advanced Use Cases
Connect SFMC to Cloud Storage (e.g., AWS S3, Azure Blob) via middleware (Mulesoft, Boomi).
Automate asset migration between Salesforce CMS and SFMC Content Builder.
Track file usage analytics using API calls and Einstein Content Selection.
🚀 Wrapping Up
File management in SFMC isn't just about storing images or uploading CSVs. It's about enabling efficiency, ensuring security, and building scalable marketing operations. When handled well, it can streamline your automation, reduce errors, and deliver a better experience to your end users.
Whether you're developing advanced automations, managing assets across BUs, or architecting an enterprise-grade solution — a solid file management strategy is essential.
