Organising EMail

Feel like you are missing important mails amidst hundreds of mails from various groups,Here is a good solution that makes use of mail filters.
1)Suppose you have subscribed to 3 groups A,B and C.

2)Create 3 Folders/Labels with names A,B and C.

3)Now go to your mail Options Filters section and create filter with the name of the group in the Subject line.If so move the mail to corresponding lable.

Ex:-Let the group you have subscribed to be XYZ, Create a folder with name XYZ.Whilst creating the filter put the subject field with XYZ.If so move the mail to XYZ folder.
By doing so, the mails from various groups will be organised in corresponding olders , hence the inbox will look clean.
Also you can set a filter in such a way that mails coming from some email IDs are moved to a specific filter,so that you will never miss those emails.(Say keep the folder name IMPORTANT).
