How to back up all email subscribers to a local file regularly

Email & Newsletters, Automation & No-Code, Files & Documents

Define what to back up, where to save it, and how often. Use a consistent export format to simplify restoration. Ensure security and traceability in the process.

Who is this for?

- Marketing teams needing offline subscriber records.
- Compliance teams auditing data retention.
- Admins maintaining backups for disaster recovery.
- Developers automating data exports for dashboards.

Before you start

- Access to the email service's export feature or API.
- A local storage location with sufficient disk space.
- Secure handling of credentials (encrypted storage).
- A schedule mechanism for regular execution.

General Process (How it works)

  1. Define backup scope and data fields Identify which subscriber fields to export (email, name, status, signup date, and custom fields) and the export format.
  2. Choose export format and destination Decide on CSV or JSON and set a local destination path.
  3. Set up automation schedule Create a recurring trigger at your chosen frequency.
  4. Implement export mechanism Use the email service export feature or API to generate the file.
  5. Validate export Compare record counts and sample data to source; run a simple integrity check.
  6. Secure and manage backups Encrypt the file at rest and restrict access.
  7. Document and monitor Record steps and monitor for failures; set up alerts.
