Create a new email on a privacy focused platform (I chose proton)
Sign up for an email relay service (Firefox relay, SimpleLogin, etc…)
Only give out your actual email to friends and family and tell them not to share it with others or services without your permission.
Change your email on ALL your services to a newly generated relay addresses. Only use relay addresses for any online service moving forward.
Monitor the old email for a while to find any important services you might have missed.
When you get spam from a relay address, you can decide to use the normal unsubscribe option, or the nuclear disable relay option. That’s it.
Bonus 01: since your changing all your services manually, you can decide to delete accounts you don’t need anymore.
Bonus 02: each relay is unique to the service so you can tell when a service either got hacked or sold your info.
Side Note: there are setups similar to this for credit cards. I use Wise.com for online transactions with 3 different “virtual” cards that I can destroy if they get exposed.
