Using a CSV file

Coro enables you to add existing email security allowlist and blocklist data by importing a CSV file containing a list of user email addresses with their corresponding list (Allow/Block).

Entries in your CSV file must follow the pattern:

<email address>,<list type>

Each entry must be on a separate line, and <list type> must be one of Allow or Block.

Files must abide by the following rules:

  • You must specify valid values in both columns. Entries with extra columns or invalid values will be ignored.
  • The maximum file size is 5 MB.
  • A maximum of 100,000 records are permitted.

To facilitate creating a valid CSV file, Coro provides a link to a template in the Upload a CSV file dialog:
