How to import subscribers from a CSV file
On the Subscribers page for the selected client, the Import CSV button opens a dialog where you upload a file with subscriber data.
File structure
- email: required
- name: optional
- tags: optional, multiple tags separated by commas
- metadata: optional, in JSON format
What happens during the import
After the upload, the result shows how many subscribers were Imported and the total number Processed. Skipped rows (usually emails already in the list) appear separately, with the reason they were skipped, and rows with errors show the exact error message for each email.
An email already in the list is automatically marked as a duplicate and skipped. It is not overwritten and does not create a second entry.
Adding subscribers manually
For a single subscriber you do not need a CSV: use the Add subscriber dialog on the Subscribers page, with a name, email, and optional tags.

Tags are manual and can be renamed; segments are saved rules (ALL/ANY groups) with a subscriber count that recalculates automatically.
