First off I've been mailing GI off and on for the past 9 years, full time for the past two. As the title suggests, I'm wondering how long mailers keep their servers online before either 1. ruining the IPs so bad they are worthless to mail on, or 2. getting shut down by your host. I realize there are many factors here such as the host's complaint tolerance, where the host is, how good the network is in the first place, data cleanliness, etc. I re-clean twice a month but inevitably still piss some people off with too much mail, hit new spam traps, etc. I remove all complaints including DNEs from affiliate networks. I've kept a list with notes of all the hosts I've used in the past year. Some are complaint tolerant, some turned off the server with the first one (just happened again today - had the server since December, got my first complaint ticket and they shut me off -first time using this particular host). In the past year I've gone through 28 servers of which 7 are currently still online. I've had some as long as 8 months and others as short as 1 month. The longer I've had them does not necessarily mean they are the best servers, only that the hosts care less about complaints. I had two servers online for 8 months that were some of the best I ever had. However, I have one online still that is pretty much crap but since they let me send all I want, it has been up for almost 7 months. So, what is your experience.... How long do you last with your hosts? Is there a good time to churn and burn?
