Send email using Workers with MailChannels

On May 13th, 2022, Erwin van der Koogh announced a partnership between Cloudflare and MailChannels to provide an email sending service specifically for Cloudflare Workers. This integration removes the friction associated with sending emails by filtering spam before sending out an email, ensuring that user-submitted content in an email won't ruin domain reputation with email providers. The best part is that it is completely free to send email using this service. The only constraint currently is that the integration only works when the request comes from a Cloudflare IP address.
