How to schedule Email

• After creating the trigger your spreadsheet is ready to schedule emails, so close your script editor.
• Go to spreadsheet and provide the details in their respective columns to schedule an Email.
• Write the Email address of the person(to whom you are sending) in the first column.
• Mention the subject and body in 2nd and 3rd column respectively. To write in multiple lines in a single cell you can use Alt+Enter.
• You can provide multiple lines in the body but you must provide a single line in the subject field.

How to mention the time

This part is very very important otherwise your Email can not be sent in proper time. You need to set the time in the format DD-MM-YYYY HH:MM. Make sure that you are putting  a single space between DD-MM-YYYY and HH:MM. You can see an example.
Example: 23-02-2012 21:17

How to know your Email has been sent

After setting everything you can close your spreadsheet. The script will read your spreadsheet in every minute and scan the schedule time. When the time will match with the current time it will send the email. If the email is sent successfully then it will make the status field Green, if it fails it will turn Red.

* Do not write anything in the status column. It will be automatically filled when the email is sent
