Video emails add the personal touch to your communications.  They are not - and will most likely will never be - a substitute to plain text emails.  Yet a well-timed video email can be the difference between and sale and a loss.  If you are doing business online, you should be creating videos and then loading them to YouTube and other video sharing sites, along w/ scheduling them in follow-up sequences.  Every time you make a new contact via phone, you should send them a video email also--it's much harder to forget a face than a name. 

TubeMogul is a free service that uploads your videos to several video sharing sites at once.
