Velocity Marketing Software has a feature that not all Email Marketing Services offer. Velocity has unlimited image hosting so that you can upload as many images you want without worrying about running out of space. This is not always offered by companies with much more expensive pricing than Velocity.
Velocity also has social Media integration. You can import contacts from your favorite social media websites as well as your email providers. This gives you a lot more options when it comes to advertising your product or service. Velocity has most, if not all, of the features as the more expensive Email Marketing Services at a less expensive rate.
