It takes a little bit of effort but it’s a great time to do the following:

• get a password manager if you don’t have one already. I like 1password
• get an alias service. Proton bought simplelogin so it’s integrated, there’s also anonaddy
• gradually work through updating your online accounts from your old gmail to new aliases for each account (eg ebay@alias.domain.com) and set a complex password through your password manager that’s unique for each account

In a couple months you’ll eventually stop receiving emails to your gmail as you work through the accounts you use, and most incoming mail will all be through aliases. Then if you get spammed, you know what site leaked your email + you can turn off the alias and not get spam.

Juse use easyoptouts. Way cheaper for same thing.
