"We're giving them what for!"
peterb - you would
but 20x30= 600 - do you really have that many REAL friends email addresses or are you just going to do some spamming / create fake adresses? - that's probs not a great idea
Regardless you still seem to be missing the "point" of the points for emails. It's not there for you to earn £££ / month spamming emails to people who have absolutely no interest in joining giffgaff - it's a way to reward you for introducing some friends who you think will be genuinely interested in what giffgaff has to offer.
You can only send an email to an address once anyway, and if you spam to hundreds of emails in giffgaff's name then it just harms the giffgaff brand and makes it highly likely that email from giffgaff will find its way onto spam filters which will massively damage future marketing efforts. The giffgaff staff are on the look out for people who attempt to "game the system" anyway and in all likelihood they would determine that what you are trying to do is just that.
