I tired that for 6 months. Fastmails crappy spam assassin bases filtering is a deal breaker. I ended up just pointing it back at my gmail. Just an inundation of spam.

I also found their search (which I rely on heavily) to be a joke compared to gmail.

I transitioned to my own domain plus fastmail years ago, and found I barely get any spam. I made sure to make a unique email per service and barely get any spam, and if I do, I can ban the email address. Helps you detect breaches or spam sales way before it becomes public.

I still have the old gmail account, but almost nothing of value goes through it.

The key is the domain, you don't even need to go away from gmail, but own your domain.
