Hi Jeff,
You can do this date conversion using an email script token. The code to use in the script would be something like:
$date.format('MMM dd, yyyy', ${convert.parseDate($company.Enablement_Date__c, 'yyyy-MM-dd')})
You would want to use the drag-and-drop UI within the email script token editor to get the exact name of the field to reference (I just guessed at the format based on your post).
The one caveat is to make sure that the date field you're converting actually contains a value (if it's null, the script can fail silently on test messages and leave you no clue what's gone wrong).
The full script, including a test for a null value, would be:
#if ( $company.Enablement_Date__c )
$date.format('MMM dd, yyyy', ${convert.parseDate($company.Enablement_Date__c, 'yyyy-MM-dd')})
#end
#* end your script with a comment so that it doesn't fail when returning no value *#
You could add more conditionals (if/then statements) to vary the format conversion by region if you wanted, as long as there's a field on the company or lead record that designates region.
If you try this, let me know whether it works. I am using something just like it in several of our email messages and it works quite nicely.
