When you launch Mail and select an email, the Daylite Mail Assistant panel at the right side of the Mail window displays options for linking and recording the email in Daylite.
To add a new email message in Daylite, select the email and click the "Add to Daylite" button.
Once added, a token having the subject of the email as its title is displayed in blue color to confirm that the email exists in Daylite.
You can also link contacts, objectives, tasks and events to the email.
