How do I send multiple emails at once?

You can send individual or multiple emails via any tab with the "Send Email" button

Check the box at the far left or each job line that you wish to send an email to (or the checkbox top right of each job on the Planner calendar or on a worksheet).

You can highlight all the jobs in view using the checkbox at the far left of the blue tool bar above any lists of data, next to the column title "Due"

Click the "Send Email" button highlighted in yellow above the data list

Create your email in the "Send Email" pop-up box, and click "Send Email" to send your message. If you want a record of the email please check the BCC self box.
