      const resp = await fetch(send_request);
  
      if(resp.status === 202) // API returns an Accepted response
      {
        return Response.redirect("thank-you-page-somewhere", 301);
      }
      else
      {
        return Response.redirect("error-page-somewhere", 301);
      }
    },
  }

note

The sending email address domain will need to be a domain that is setup within Cloudflare.

As of August 2023, a TXT record will need to be created as per the following:

• NAME: _mailchannels, CONTENT: v=mc1 cfid={YOUR_WORKER_SUBDOMAIN}

Further, if you use CF Email Forwarding, you will need to update your existing TXT record for the forwarding to the following:

• NAME: @, CONTENT: v=spf1 include:_spf.mx.cloudflare.net include:relay.mailchannels.net -all
