Know-How Exchange : E-Marketing

-On your website
-On your blog
-On all company newsletters, mail outs etc.
-A link and little message at the bottom of everyone's email signature
-Financial Planners
-Contact the local college's professors in finance, economics etc. and tell them you were thinking their students might find this e-book helpful.

I would BLAST it out to everyone in your database in a short but sweet auto-response-

Make SURE you have a GREAT subject line.

You can create a study GROUP for it on Facebook, and then tag everyone your friends with...

I have a lot of experience with content marketing. I have promoted any new content in the following ways:

-introduce via email campaign. Reminder emails to those who didn't open the first one
-on home page of website and customer service portal
-on home page of client portal if you have one
-on blog if you have one
-suggest having archive area on your website if you don't have one or if don't have a blog-launch it there
-promote through any partners you have-for example, we had association partners and we asked them to send out emails we created to promote to their members and to post links on their site
-if you have a newsletter, promote it there
-add to "welcome" letters for new clients
-add link to any sales letters going to prospects/clients

Good luck!
