How I Cleaned Up My Gmail Account

My Gmail account is more like a trash can. Piles and piles of emails dumping in every day. I even scan through them daily, looking for exciting and valuable information. I really didn't bother organizing it. It became a mess with ~29,00 emails in the Inbox. I start to run out of space. Therefore, I decided to clean it up. 

Stop Emails 
The first thing is to find out emails I have no interest in reading and remove them by unsubscribing to a mailing list, reporting spam, or blocking the sender. 

Delete Emails
For promotion emails and newsletter updates like neighborhood news and LinkedIn job alerts, I like to scan through them daily but don't want to bother to delete or archive them after the read. So I create Gmail queries, which I can put into my "Search mail" text box to find them all during email clean-up and delete them in a Batch. Note the OR and AND operator has to be capitalized. 

Example: 
OR {from:[email protected], 
from:[email protected],
from:[email protected], 
from:[email protected],
from:[email protected], 
from:[email protected], 
from:[email protected], 
from:[email protected], 
from:[email protected], 
from:[email protected], 
from:[email protected], 
from:[email protected],
from:[email protected]} -is:starred​

Archive Emails
For emails to keep, I created two folders one "MyArchived" folder with a subfolder in years to keep emails per time and one "Saved" folder to keep emails based on projects or contact persons that are significant. 

Search emails based on the time in a year, select the current page, and then select "Select all conversations that match this search." Apply the archive label. Select "Select all conversations that match this search" again and click on the "Archive" menu. 

Example: 
​after:2018/1/1 before:2018/12/31 

Group Emails 
The last step is to group email with the Google default "Primary," "Social," "Promotions," "Updates," and "Forum" in Tabs. 

With this, my Gmail is decluttered and ready for a fresh start.
