Hey people, I am a linux guy, and I hate windows. So I had to make this script in Python, and it needs GTK to run. You can very well run this on Windows if you have python and GTK and MySql installed in it. This is the best of them all I guess, or maybe I think so, cos I made it . The software has 3 tabs, one is the Batch creator, another is a Content Generator, and the other is the Mailer. Batch Creator You can subscribe to only 200 groups from one single mail id, so to mail around 100k groups, you will need 5k email ids to subscribe to all of them. With the batch creator, you can create any number of such batches. 1 'From' id, and 200 'To' ids. Content Generator I use the NVSB-V4 here for all my sites. The content generator asks you for a keyword, and with that keyword, it fetches youtube's RSS and extracts the video ids, and makes a URL for the nvsb with the video id in the required format, and saves 5 such links for each message The Mailer The mailer has a dropdown, from which you can select messages stored in the db by the content generator, and click on the send button, and it keeps on sending to batch after another in the Batches Tab. Installation Like I said, if you are on Windows, you will need to install Python and GTK, and mysql. Open the codes and fill in the SMTP details and the DB details. Run the SetupBomber.py to setup the db. Get on to work. Add-Ons I have an ID collector and a subscriber which will save you a lot of work, and will get you atleast 1000 new group subscriptions a day, which I am willing to 'sell', or give away for free depending on the response I get for this thread. I had plans to sell this on BHW, but HARRO never got back to my PM. So decided to give it away for free. I really wanted to give something in return to BHW. When you send mails in such huge volumes, and as you would be receiving mails in huge volumes from all those groups you have subscribed to, you will need a good VPS or a server for that. I request you to PM me for my affiliate link . Don't even think of subscribing with free Gmail ids. The best way to do it is to get $2 domains from yahoo, and create 50 ids per domain and use them. I configure and gear up servers too, and that I do for money. Here are the screenshots, and the script. Have fun. Do you see a Thanks button down there?
