When it come to GI, lots of people will say to mail 24/7. Never let those servers rest. But what I have noticed is that most action will happen during the busy hours of 8am - 9pm. After that the sales/residuals are hardly impressive. So would it even be worth using up valuable resources like IPs and domains during these hours? Wouldn't it be better to back off the domains and IPs if the blacklists you end up on are not so serious? After cleaning, some of the blacklists i get on are not as critical as say DBLs, Barracudas, etc. Some of the lists i get on allow IP removal with the click of a button. What say you?
