DNS & Email Setup

MX Records

Point your domain’s MX records to Cloudflare Email Routing:

MX  yourdomain.com  →  route1.mx.cloudflare.net  (priority 1)
MX  yourdomain.com  →  route2.mx.cloudflare.net  (priority 2)
MX  yourdomain.com  →  route3.mx.cloudflare.net  (priority 3)

Caution

Changing MX records affects all incoming email for your domain. If you’re using an existing email provider (e.g., Google Workspace, Proton Mail), read the section on coexistence below.

Keep Existing Outbound Sending

If you use a provider like Proton Mail or Google Workspace for sending, keep your existing SPF, DKIM, and DMARC records intact:

TXT  yourdomain.com              →  v=spf1 include:_spf.protonmail.ch ~all
CNAME protonmail._domainkey...   →  (your existing DKIM record)
TXT  _dmarc.yourdomain.com      →  v=DMARC1; p=none; ...

Cloudflare Email Routing

1. Go to your domain in the Cloudflare dashboard
2. Navigate to Email > Email Routing
3. Enable Email Routing if not already enabled
4. Under Routing rules, create either:
   • A catch-all rule → route to your Email Worker
   • Specific address rules (e.g., contact@yourdomain.com → Email Worker)

Verify It Works

Send a test email to your configured address. Check the worker logs:

cd worker
wrangler tail

You should see the email being received, classified, and stored in D1.
