Can put arbitrary TCP/UDP services behind Cloudflare Spectrum and send outbound emails through a relay to avoid leaking IP but they aren't technical enough to set it up. It's only on paid plans and has extremely low (5GB/10GB per month) bandwidth included with $1/GB beyond it.

It'd be hilarious if they did because they'd go bankrupt from it. Metered services are awful esp. with attacks and almost everything Cloudflare offers other than their caching reverse web content proxy is an expensive metered service (load balancing, video/audio, TCP/UDP proxy).

Reference for Spectrum billing: support.cloudflare.com/hc/en-us/artic So for example if someone sent them 2TB of data it would cost them $2000. Supposedly Cloudflare won't bill you for attack traffic but that's a fantasy. Good luck trying to get bills cancelled by arguing it's all attacks.

5GB/mo might as well be infinite for email (assuming you're not a spammer).

This would only be for inbound connections via Cloudflare Spectrum and you'd have to handle your outbound connections with your own relay to hide your main MX IPs. The problem being that you're being billed for spam and people could spam you to bankrupt you.
