Reselling Cloudflare Email Routing


Am I able to resell (or effectively re-route) Cloudflare’s Email Routing?

I host a temporary email website, and a lot of the IP addresses associated with my domains get flagged easily. It would be nice if I could use Email Routing for my domains. As well, I allow people to use custom domains on my site. I want to know if it is at all possible to give those people this service without having them register their own Cloudflare account and setup email routing. Custom domains are a monthly subscription which is why I am asking this question.

Thanks in advance,
