Recently, in Pakistan many companies have started offering email marketing.
These companies collect email data from various sources, and then start sending emails in bulk.
Majority of these email marketing companies are using Google groups to send emails.
Google groups enables them to build an email database and thru these groups then can send bulk emails.
Many people have complained about being added without their consent and receiving several emails on daily basis. Because of a Ban/unban bug in Google Groups, I myself reported Google to fix that bug, but no response yet from their side.
Here is how you can unsubscribe google groups, and make sure that no one can add you again.
Create an account on Google at : http://accounts.google.com
You can use your company email address to create an account.
Google will send you verification email which you should verify.
Once you create the account, you will see the main dashboard page.
Add as many emails as you want in the same account ( usually the ones which are receiving SPAM mails from Google groups)
Once you have added all the accounts.
Go to dashboard –
At the lower part of the screen there is a link for GROUPS
Click on the link.
On the lower right hand side of the screen, you will find the option for “manage subscription”
Or Open : http://groups.google.com (without logging off, off-course)
Click on My Groups
Once you click on that link, you will see how many companies / groups have added your emails address.
Click on the group which subscribed you without your permission or you don’t want to be part of that group.
Click “My Membership” from here you can select the option to unsubscribe from that mailing list.
That’s it !!! and now you are done !!
Also, from the User Preference option (click on settings icon 
):-
You can enable the option to :
- not to allow any other company to add you
- not to send any other Google group emails.
The Google group spam has been there for a while and many people have been asking me about how to avoid the spam.
I hope this will help to unsubscribe and reduce the spam from Google groups.
