Manual submissions service providers argue that automatic submission are not effective...but directories cannot make difference between a submission made by MyPersonalSubmitter and a fully manual submission.
An automatic Submitter at a lowest price
For $59, MyPersonalSubmitter proposes a fully automatic mode; submitter at same price are often semi-automatic software, where you have to click each directory. Automatic submitter are much more expansive, or time-limited, and work only with an unique submission page for all categories (if a directory requires you to navigate before submission, they fail).
