> You're not paying for forwarding, you're paying for someone to host a whole email stack for you (and the associated dev work such as on clients).
I know, and I love ProtonMail (for example) for that, but my use would just be forwarding and not storage or access. In my use case it would feel like overpaying.
> You can choose to use a "free" provider like Gmail if you're ok with paying with your data and a lack of features (such as not being able to use a custom domain).
It's versus G Suite Free (which is my secondary, "online name" email), my main (real name) email has to stay at Gmail because I'm afraid of the mountain of account resets I'd have to do. To be fair, this whole value consideration was back when Google were threatening to kill off G Suite Free entirely (a few months ago), so it was paid-versus-paid then.
> Also by the way, Fastmail is half the price you list at $5/month
Fair, $10/month was off the top of my head.
