Anyone out there collecting their own email addys? I have a list that is growing daily, and i wanted to know the best way to utilise this traffic. Should i do mail outs daily, or will this piss people off?? Do i send out mails with links to a daily gallery with some advertising, or am i better off making a html style email with agressive advertising and a few pics that are impossible to find? I'm very new to this style of traffic so any feedback would be much appreciated.
Cheers
Sloane.
