Actually automated submissions are a complete no. if you want your website to have a good positioning in search engines. Automated submissions create more harm than advantages. Major Search engines and directories like Google and domz does not allow automated submissions at any cost. And all other search engines also prefer manual submissions. The automated submissions software can only fill out the submission form automatically but this is not enough for search engine and directory submissions. The most important step involved in submissions is to select the most relevant category. This can no be done by automated soft wares. Automated submissions can also lead to server overload and vulnerability to denial of service attacks hence manual submission is considered better much better than automated submissions even though it is time consuming. The time spent in manual submissions is worth it because your website is sure to start receiving good quality visitors once it is indexed by the search engines and directories.
