Basically, this is something I need to do for work.
I have a list of about 280 e-mails in an Excel doc that I need to send as a mass e-mailer through my work e-mail address. I have been told to convert it to a .csv file so I can then copy and paste into the BCC line. The ISP I use for my e-mail is Gmail.
Hopefully this will make sense to someone out there.
I will be eternally grateful for any advice, and will obviously rep where I can.
