What you need to have before you start
I assume that you already have a domain, let’s call it “yourdomain.com”. Specifically, you need to have accessibility to connect your domain with Cloudflare and setup DNS records there. A classic example of that is having a domain on some domain registrar (like GoDaddy, Namecheap), and adding your domain to Cloudflare by setting DNS records provided by Cloudflare on your domain registrar account.

Adding a domain to Cloudflare involves updating your domain’s DNS nameservers to point to Cloudflare’s nameservers. Once the domain is added, Cloudflare acts as an intermediary for web traffic, providing security features like DDoS protection, firewall, and SSL encryption, as well as performance enhancements through caching and content optimization.

If you haven’t done that yet, here’s the official video on YouTube on how to connect your domain to Cloudflare.

Additionally, Cloudflare manages DNS records for your domain, allowing you to control how traffic is routed and ensuring reliable delivery of services like email.
So, our work in this article will be focusing exactly on that: how to setup your domain on Cloudflare Email.

Cloudflare Email has been one of the services of Cloudflare since 2021, which can be used for free (as of now, at least).

Email Routing on Cloudflare

Cloudflare Email Routing is designed to simplify the way you create and manage email addresses, without needing to keep an eye on additional mailboxes. With Email Routing, you can create any number of custom email addresses to use in situations where you do not want to share your primary email address, such as when you subscribe to a new service or newsletter. Emails are then routed to your preferred email inbox, without you ever having to expose your primary email address. (Cloudflare Docs)
