What did you do with semi-trusted emails? - midwest.social

Curious for any input on this - I want to finish migrating off the gmail I’ve had since 2004. I’ve moved everything vital, utilities, banks, financial services, doctors, vets, etc, to proton. But what about spammy or untrusted services, or general e-commerce? Think sweetwater, etsy, newegg, etc. I could create an alias in proton, but I really like being able to have notifications on for the proton mail app; if someone emails me there it actually matters. So, I don’t want to lose access to these services, and I don’t want to give them an email that matters. Do I need another provider? Is there a better solution?
