Batch import mailing lists 

Administrators can go to Lark Admin Console > Product Settings > Mail > Account management > Mailing List and click Batch Import > Import via template.

Click to download the import template and fill it in following the instructions.

If the import fails, the page will display a list of members that failed to be imported and the reason for failure. You can download the error report, edit the information in the import template, and try again.

Batch export and edit mailing lists 

Select all or check the mailing lists you want to export. Once you're done, click Export.

Note: A maximum of 20,000 mailing list email addresses can be exported each time. Don't close or refresh the page while the export is in progress. It usually takes a few minutes. 

After completion, you can see the export result.

Edit the mailing list information in the exported file and click Batch import to upload it. After completion, you can see the import result.
