Email service with automatic gmail list importer

This post should have gone hot off the BHW today because it is really important. In a time where there is no email service company that is providing it without footer links and logo. No any email service company is giving out a plan where user can send campaign without the credit link in the source of the template but this company is giving out premium services. I enjoyed it and you too can grab this opportunity. I found it on a thread in BHW here and would like to share it with all of you about this company.
But i still have a question that i joined that company and as i used gmail extracot there, i got my email contact automatically imported. Is my list yet secure?
