Here are some of my favorite services I use and feel confident in recommending. Some are affiliate links.

WP Engine. Managed WordPress hosting with daily backups, malware scanning by Sucuri, and fast servers. Company is owned by the makers of WordPress. I host my business site with them. Various sized options from one website to enterprise level. (Psst – get 20% off your first payment, use code wpe20off.)
Best for Techs – LiquidWeb. Absolutely the best tech support, rock solid security and very knowledgeable. Available 24/7 via phone and excellent support ticket system. This is one of two companies I refer clients to with multiple websites and also use for my development purposes.

Sucuri. Malware infections on your site are expensive fixes. Protect your valuable website with Sucuri, they will monitor your site for against malware and has free malware cleanup should an incident happen.
Favorite Plugins for WordPress
Gravity Forms. Connects to Mail Chimp (one of my favorite email campaign list management software), Akismet, Paypal and many others.
Email List Campaign Management
MailChimp. There are several great email campaign list managers (Constant Contact, iContact) but this one has the most connections with other services. That last part has what the others lack in spades – plus they are easy to use. You have no problem with easy right? You might enjoy the fun interface (comments can be turned off if you are less than amused).
