Use excel to automatically send emails

Hi,
Is it possible to use Excel to send an email? I want to run a macro that emails a member of staff to tell them that a due date for a project is approaching, so it needs to be sent under certain conditions, for instance when cell D8 equals 1 or less. I would also like it to be able to contain information collected from the spreadsheet, so that cells A8, C8 and D11, which contain customer and project information can be sent to the member of staff in an email which also contains other text.
Is this even possible with Excel?
Please advise.
