Hi teanas1,
No ones helped you out yet! I'm not sure I'll be 100% help, but I'll do my best. Can't leave you hanging for to long, you might think this forums ignoring you
:)
SEO Software: The only thing I can recommend, before you buy anything is to check out Stomping the Search Engines (Brad Fallon). Just take peak. His system was featured in Wall Street Journal and Entrepreneur Radio. He's used by a lot of big sites...
E-Mail Marketing: I'm not 100% sure what kind of marketing software you looking for. I use Constant Contact. I have a newsletter, reports, alerts, you name it and Constant Contact manages it all. They give you a 60 day free trial. It's worth checking out.
The easiest thing for you to do is just go to my website. I have a free eCourse. Lesson two talks about online marketing in general; maybe you'll pick up some ideas. You'll find towards the bottom "other avenues". That's where you'll find more
info on SEO and E-Mail Marketing and links to the above resources.

Otherwise, you might want to check out the Search Engine forum and see if you can get a better solution over there about
SEO Software.
I hope I've helped at least a little.
Good Luck in Your Endeavors!
