Do you use the Gmail account for everything (bills, user accounts, personal correspondence, etc.)? That can determine how difficult and time-consuming it will be. I've been reorganizing my email usage the past few years. I first adopted a ProtonMail email for all accounts related to financial data. That just involved going to each bank, credit card, loan, etc. and following the update email address process for each. It doesn't take too long. More recently, I moved everything else from Outlook.com to an email address using my own custom domain. I set Outlook.com to forward/redirect all email to the new address and then made a filter/rule on the custom domain email address to drop all mail addressed into a folder. As mail comes into this folder, I take whatever action is necessary to either update the sender that my email address has changed, or stop receiving email from that sender by unsubscribing or whatever.
