How to Add External Recipients to an Email Message

You can access this feature from your MSL website. Only Organisation Admins with permissions to send messages can access the Send Email window.


For information about how to enable the External Recipients window for an organisation, see How to Allow External Recipient Messaging.


To add external recipients from a file, ensure that the file is in Excel (.xlsx) or comma/tab-separated text format. 
The file should either have a single column for email addresses or three columns in this order: Email Address, First Name, Last Name.
Remove any column headers before uploading.


Before proceeding, when sending to external recipients, MSL doesn't track open rates. Instead, use Google Campaigns for tracking. For further information, see How to Track Email Insights Using Google Campaigns.


Uploaded files aren't saved, so you'll have to upload the list whenever you message external recipients.


For further information, see Send Email.
