Entire portfolio (bulk)
To add or update TXT and/or MX records for your entire portfolio you navigate to Settings > Bulk DNS. Here you can add, update or remove records for your entire portfolio. Depending on the size of your portfolio, it might take some time for these changes to propagate. Changes made via the Bulk DNS will overwrite any changes you’ve previously made for individual domain names.
