There are situations when you may want to find all the big emails stored in your Gmail inbox. Although Gmail provides 7 Gigabytes of free space to all its users, sometimes you may end up discovering that only a few megabytes of space are remaining. If you have been using Gmail since the service was launched, chances are that your email inbox is full of attachments or documents you don’t need.
When your Gmail inbox is almost full, the following warning message appears:
“You have run out of space for your Gmail account. You will not be able to send or receive any emails until you delete some items”
In such situations, you might want to find all the emails that contain big attachments, useless images or documents. This is when FindBigmail is useful; the service will scan your Gmail inbox and filter all the emails that are consuming unnecessary space in your Gmail account.
Here are the steps you need to take:
1. First, go to FindBigmail  and enter your Gmail username, as shown below:
