Send email using Cloudflare Custom Domain
To send emails using a custom domain managed on Cloudflare, follow these steps:
1. Choose an Email Sending Service
I used Mailjet because it's a performant French solution, it was super easy to set-up.
- Mailjet (France) 🇫🇷
- HQ: Paris, France
- Features:
- SMTP relay & API
- Transactional & marketing emails
- Advanced analytics & A/B testing
- Pricing: Free tier (6,000 emails/month), paid plans start at ~€15/month
- Website: https://www.mailjet.com
2. Configure your Email Sending Service
- Create account
- Configure domain by creating a TXT DNS entry (see help)
- Configure SPF by creating a TXT DNS entry (see help)
- Configure DKIM by creating a TXT DNS entry (see help)
- Add an Sender Address from your dashboard
- Get Your API Keys from this page (see help)
3. Configure Django
Add the below in your settings.py file.
EMAIL_BACKEND = "django.core.mail.backends.smtp.EmailBackend"
EMAIL_HOST = "in-v3.mailjet.com"
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = "your-mailjet-api-key" # Replace with your API Key
EMAIL_HOST_PASSWORD = "your-mailjet-secret-key" # Replace with your Secret Key
DEFAULT_FROM_EMAIL = "[email protected]" # Use an email associated with your domain
You're ready to go!
4. Receive email to your custom domain
Has to be done in Cloudflare
- Set-up domain
- It will add several DNS entries: one of them is in conflict with the one used for SPF configuration
- Accepts the changes: it will break the SPF configuration
- Go to MailJet
- Check the SPF configuration: it proposes a change, that adds the MailJet SPF on top of the Cloudflare
- As in
"v=spf1 include:spf.mailjet.com include:_spf.mx.cloudflare.net ~all"
- As in
- Back in Cloudflare, Email Routing
- Check Destination Adress: You should see your domain
- In Cloudflare, Règles d'acheminement
- Create a Custom Adress
You're done !
