I love how easy it is! It's super simple, but powerful at almost any level you can think of -- even basic things like having multiple lists with different colors makes sense (and looks great!) You have full control over all aspects about what shows up in each list/group etc., including custom images / backgrounds as well, which are just amazing when compared side by slside w/other services that don't offer this option easily enough!! Honestly everything so far? The only thing i dislike thusfar might be their pricing system - not everyone has $5k free per year lying around waiting patiently, haha! But otherwise nothing much really :). Super clear instructions & helpful support team if anything was needed :) Highly recommend using them now before price increases kick into gear ;) My client base grows weekly thanks market volts' ease! Being able get clients signed right off an email address without needing separate account login details helps immensely too, saves time overall :) I like the way I can easily segment and organize my contacts and the way I can add more contacts to my database. The price is a little high for my budget. I would like to see more features and a lower price. I have been using Marketvolt to help me build my database and to help me create a signup form for my website. I am able to easily organize my contacts and have a database that I can easily segment. I am also able to add more contacts to my database so that I can send them more information.
