What about Google GMail? Do they have limits as to how many emails you can send using gmail account? Of course, you'd have to have your local mailer/manager application.
Dear Kartik & other DP members, for your review let me share this shareware with you guys .... Review: Super Email Sender is a professional high speed bulk email direct sender program. It is an ideal for newsletters, targeted marketing, and keeping in touch with clients. Super Email Sender accepts a list of recipients from text files generated by any email harvester(Such as Super Email Spider). The number of addresses to be sent is unlimited. You can send email to a million people if you want. Super Email Sender is a stand-alone bulk mailer program. All you need is a connection to the Internet, the program has its own internal SMTP server and delivers mail messages directly to email recipients without your ISP SMTP server. The normal sending speed can be up to 50000 e-mails per hour. It also has a professional and simple user interface so that everyone can set it up in few minutes. http://www.programurl.com/software-super-email-sender-downloadnow.html This is a download link if you guys want to give it a try ....

Those programs do not work anymore Tirmizi. ISP's block emails that are not sent through proper SMTP servers.
From what I understand, Constant Contact has a good delivery rate. They also have responsive customer support.
