sending email based on a gridview column containing email addresses
===

May I know how to send email based on gridview column containing email addresses?
I am currently using asp.net and c#. I'm also currently using smtp gmail for the email. 

Currently, I had a gridview1 which contain customers (email, name, accountNo) that had bounced cheque, however I wish to send an standard email, to all these customers upon clicking a button. May I know how should i go about it? Their email is stored in database and will be shown on gridview.
