Anti-Spam & DMARC
Uses Google’s high-reputation outbound IP pools coupled with Cloudflare DNS-enforced SPF and DMARC alignments for pristine inboxing.
02 / INTERACTIVE SETUP TRACKER
Step-by-step checklist.
Follow along in your Cloudflare and Google account settings. Check off each step as you complete it:
03 / INCOMING ROUTING CONFIGURATION
1. Enable Cloudflare Email Routing.
Log in to the Cloudflare Dashboard , select your domain, and click Email → Email Routing.
1
Add Destination Address
Under Destination addresses, add your personal Gmail address (e.g. [email protected]). Cloudflare will send a verification link to that inbox. Click the link to verify.
2
Create Custom Address
Under Custom addresses, click Create address. Enter hello (or contact) and set the action to Send to [email protected].
3
Auto-Apply DNS Records
Cloudflare will prompt to automatically insert 3 MX records and 1 SPF TXT record into your DNS table with a single click.
| Type | Name | Value / Target | Priority |
|---|---|---|---|
MX | @ | route1.mx.cloudflare.net | 48 |
MX | @ | route2.mx.cloudflare.net | 55 |
MX | @ | route3.mx.cloudflare.net | 78 |
TXT | @ | v=spf1 include:_spf.mx.cloudflare.net ~all | — |
04 / OUTGOING TWO-WAY SENDING
2. Send from [email protected] inside Gmail.
Now you can receive emails. But when you reply, you want your reply to say From: [email protected] instead of your personal Gmail. Here is how to configure free outgoing SMTP in 3 minutes:
A
Generate a Google App Password
1. Visit Google Account Security and ensure 2-Step Verification is ON.
2. Search for App passwords (or visit myaccount.google.com/apppasswords).
3. Create a new App Password named "Cloudflare Custom Email".
4. Copy the generated 16-character code (e.g. abcd efgh ijkl mnop).
B
Add 'Send mail as' in Gmail
1. Open Gmail → Settings (Gear icon) → See all settings → Accounts and Import.
2. In the "Send mail as:" section, click Add another email address.
3. Enter your Name and your custom email (e.g. [email protected]). Uncheck "Treat as an alias".
4. Click Next Step.
C
Fill in SMTP Server Credentials
- SMTP Server: smtp.gmail.com
- Port: 587
- Username: Your personal Gmail address (e.g. [email protected])
- Password: The 16-character Google App Password created in step A.
- Secured connection: TLS (recommended).
D
Verify Confirmation Code
Google will send a confirmation code to [email protected]. Because Cloudflare is already forwarding to your Gmail, the code will land in your inbox within seconds! Enter the code to confirm.
05 / DELIVERABILITY & SECURITY
3. Hardening SPF & DMARC for 10/10 Inboxing.
Major mail providers (Google, Yahoo, Apple Mail) enforce strict authentication. Because you are receiving via Cloudflare and sending via Google SMTP, combine both in your SPF record so neither flags your emails as spoofed:
| Record | Name | Value | Why it's essential |
|---|---|---|---|
TXT | @ | v=spf1 include:_spf.mx.cloudflare.net include:_spf.google.com ~all | Authorizes both Cloudflare routing and Google's outbound SMTP servers. |
TXT | _dmarc | v=DMARC1; p=none; rua=mailto:[email protected] | Protects your brand domain from phishing and impersonation attacks. |

Common questions.
Will my personal Gmail leak?
When sending via Google SMTP with App Passwords, the From: header displays your custom domain (e.g. [email protected]). Most recipients only see your professional domain address.
Can I have multiple aliases?
Yes! You can configure unlimited aliases in Cloudflare (contact@, press@, billing@, jobs@) or enable a Catch-all rule to route all incoming mail to the same Gmail.
What is the daily sending limit?
Standard free Google accounts allow up to 500 sent emails per day, which is more than enough for portfolios, consultants, and developers.
How do I test my deliverability?
Send a test email from your Gmail (selecting your custom domain address) to mail-tester.com . With the combined SPF and DMARC records above, you will score a perfect 10/10.
