VBA is Visual Basic for Applications.
It is part of your MS Office application.
VBA is used to create code to assist Office applications with repetitive tasks
or tasks that cannot be be done natively.
Typing email addresses in your worksheet is just the start of your task.
Now you want to send a group email to those addresses on the list.
Excel cannot do this all on its own. Excel is quite dumb when it comes to
that type of operation.
I referred you to Ron's site because he has done all the work of coding.
With Excel closed..........
Download his SendMail add-in, stick it in your Office\Library then open your
workbook in Excel.
Go to Tools>Add-ins and checkmark the Sendmail add-in.
Depending upon what type of group email you want to send and what you will
send, the add-in will assist.
