You can add a little post-script to the end of your email copy, such as "Not responsible for your company's social media? Feel free to forward this ebook to a friend or colleague using social media marketing." Link the call-to-action to a pre-made email, complete with subject and body text. That way, all someone has to do is enter their associates' email addresses and hit "Send." 

Very well written article! Thanks for sharing!!! Just that I would add another tool to this list- intellyMail.com. It is really one of the best email marketing tools that I have come across. intellyMail eliminates the need of manually sending bulk emails through an automated process, thus saving you time and money, besides helping you generate leads
The post is very informative and the list you have shared with is great, but the Constant Contact is good I think to start the company as the live chat features are powerful in it can solve the one query on time. But it’s chargeable that to $20 at least it should be $10, I don’t know much about its but I’ll try for that free package and check it. Thank You.
This article is by far one of the most interesting and fun articles that I have read in a long time. I say fun because the points mentioned here are simple and easy to read. They are not long passages that speak a lot and tends to lose focus. On the contrary the points mentioned here were in short crisp sentences that did not bore me but made my read a pleasurable one. Thanks!
Another way to extend the clicks on your email beyond its shelf life is to prompt your audience to forward the offer. The folks at Litmus found that the most forwarded emails were 13X more likely than the typical email to include “Share With Your Network” calls-to-action. By including forward-to-a-friend (or social sharing links, as we discussed above), you put it in recipients' minds to share.
