1. Create a filter for emails from Twitter :

Go to Gmail Settings > Filters > Create a new filter

In the From text box use Twitter . Then just click Test search to find if that is really working and click Next Step >>

In the next window check the options Skip the inbox (Archive it) and Apply the label and create a new label from the drop down box. I used the label Twitter

NB: Checking the Skip the inbox option is important, otherwise you will see the email in both your actual inbox and new inbox

2. Using the Multiple inboxes feature

Multiple Inboxes is a Gmail labs feature so you have to enable that first. Goto Settings > Labs and find the Multiple Inboxes feature .enable it using the enable radio button and Save your changes.

You can add a number of inboxes. For adding  a new inbox for your Twitter emails use label:Twitter in the first text box. (since I used Twitter as the label name).

You can choose the number of emails to be shown and also the position of the new inbox.

That’s it now when ever you open your Gmail you see a multiple inboxes. Filters are a power feature of Gmail. You can used them along with some Gmail labs features such as Canned Responses to create amazing results. So  do experiment with them. You can use the same idea to manage your newsletter and rss subscriptions and lots more.
