Basic text-based email editors to fully designed HTML or JavaScript templates are just some of the features these packages can provide businesses. You can manage your contacts by simply keeping a list of names and email addresses or you can create a complex database full of subscribers segmented by demographic slices and engagement levels. Which method you choose really just depends on how much of your budget you're willing to allocate towards the email marketing software that can give your company the features it needs.
Every week, the folks at InVision send a roundup of their best blog content, their favorite design links from the week, and a new opportunity to win a free t-shirt. (Seriously.

Most of the article really talks about how to successfully get an email of a person who has already landed on your landing page/podcast page/affiliate/blog etc. but how to get those people there in the first place is a bigger challenge. Also, one of the ways you can include in your list is by offering free tools/widgets. For example, OpenSiteExplorer by Moz is a great example. Evergreen and very useful for the target audience.

A blast furnace is used to create pig iron from iron ore. It is a large vertical chamber lined with refactory (heat resistant) material into which iron ore, lime and charcoal is dropped. The charcoal is burned, with the help of compressed air blowin into the bottom of the chamber via ducts called tuyere's. This generates enough heat for the charcoal to react with the iron ore, effectively stripping out the excess oxygen and leaving the iron behind. After the process has run for some time, the impure pig iron is drained from the bottom of the chamber. The pig iron gets its name from the grid of ducts the iron was drained into, because it resembed piglets suckling alongside the mother.

An omni-channel approach not only benefits consumers but also benefits business bottom line: Research suggests that customers spend more than double when purchasing through an omni-channel retailer as opposed to a single-channel retailer, and are often more loyal. This could be due to the ease of purchase and the wider availability of products.[24]
