There are many prominent promotional emails in your mail. It is often a waste of time to find important emails in unnecessary mail ships. To get rid of this problem Gmail is always spamming all mail IDs that can be blocked from them. How to easily perform the task is highlighted in this tutorial.
After logging into the Gmail ID, you will need to go to the Settings option by clicking the Settings icon at the top right. Then a new page will be launched. From there click on 'filters and blocked addresses'.
Then click on 'create a new filter' option.
The next step will be to introduce a new popup page. There you will be given the option to block the mail id in the 'From' option. Then click on the 'create filter with this search' option. Then again a new popup page will be launched. Select the option 'delete it' and click on 'create filter'. Only mail from the selected mail ID will be automatically deleted.
