Unnecessary e-mails accumulate and many times useful e-mails cannot enter. Many people do not understand why this is happening despite having 15 GB free storage. This usually happens when the storage is full. Sometimes so much junk mail comes, it fills up 15 GB of free storage. After that useful mail also stopped coming. There is an easy way out of this problem.
How to delete unnecessary emails
* Log in to Gmail first. Go to the search bar at the top and enter the email address of the sender you want to delete. You can select all mails sent by that sender. Or you can select the option from which date you want to delete the email
* After selecting, click on the rectangular checkbox at the top of the inbox. Select from there and click on delete. Then click on the trash icon. Select all emails in the trash and permanently delete them.
* In addition, all emails in the inbox can be deleted at once. In this case, first login to the Gmail account. Then click on a checkbox at the very top of your inbox. With the help of this all the mails of the page can be selected and deleted at once. But be careful while deleting all these, so that no essential mail is deleted.
