There are 3 things I feel are necessary for any online business: A Website, an Autoresponder and Traffic.
I have always gotten my domains from GoDaddy. I love their customer service and tech support. I currently have them hosting my website also. It seems they now have wordpress blog support., that helps.
As for an autoresponder., I have tried many. In starting out, I did not have the resources for a monthly expense. I recently found an autoresponder that is easy to understand and manipulate thru. They also offer their system free until you have 100 subscribers. You can find them here.
The most important part of a successful business, virtual or ‘brick & mortar’, is TRAFFIC. It took me a long time to realize that. Without it, you go nowhere. People have to be able to find you. The internet is a huge platform, so, you have to learn how to spread the word that you have a blog, a product, whatever you are promoting. I decided to use Leased Ad Space, there is a link to the right. I also use IBOToolBox, which is a free site. There are optional upgrades. That seems to take care of the traffic aspect, but, for me., I had nothing to sell or promote. That is until I started to learn about cryptocurrency., i.e. bitcoin and many others.
