As we all know marketing on the web is rather like the Red Queen's problem in Alice in Wonderland. You've got to run ever faster just to stand still. As soon as you come up wih a reasonable or decent technique then someone else comes up with a way of blocking you getting your message out.
One way to get yourself a leg up in this race is to use a specialist hosting company: like Fat Jack for example. Yes, they do all of the regular hosting plans: $5.77 a month for a basic server space, just under $20 a month for private hosting and so on. But hen there are hundreds of other companies out there offering such deals.
What sets Fat Jack Hosting apart is their specialty in hosting email campaigns. They'll monitor the deliverability of your messages (which is, in these days of spam filters, the most difficult part of the process) on an ongoing basis: this helps you to work out when and where campaigns are succceding and when they are not.
If you're in this part of the marketing business then Fat Jack is definitely worth checking out.
