I like that you can upload images to be used in signature image, this makes it easy for me to update my sig when needed. It is not as intuitive as other programs out there (like MailChimp) so some people might find it confusing at first. However, once they figure it out, it's pretty straight forward. Make sure to do thorough research before choosing software/program. We were looking for something simple where we could easily add our logo to each e-mail sent from our account. This allowed us to have consistent branding throughout our business without any extra work or cost.
