What Is Domain Connect? — Email Security
The Problem: DNS Is Hard
Setting up email authentication means editing DNS records — TXT records for SPF and DMARC, CNAME or TXT records for DKIM. For many domain owners this is confusing, error-prone, and time-consuming. A single typo in an SPF record can break email delivery. A missing DKIM key can cause legitimate emails to land in spam.
This is where Domain Connect comes in.
What Is Domain Connect?
Domain Connect is an open protocol that simplifies DNS configuration by allowing service providers to automatically create or update DNS records at supported hosting providers. It eliminates manual DNS editing for email authentication setup including SPF, DKIM, DMARC, and MTA-STS records.
Domain Connect is an open standard that lets service providers automatically configure DNS records on behalf of the user. Instead of copying cryptic values into your DNS zone, you click a button, confirm the change at your DNS provider, and the records are created for you — correctly and instantly.
The protocol was originally developed by GoDaddy and has since become an open standard with an IETF Internet Draft. It is backed by a growing ecosystem of DNS providers and service providers.
How It Works
Domain Connect involves two parties:
- DNS Provider — the company that hosts your domain’s DNS (e.g. Cloudflare, IONOS, GoDaddy)
- Service Provider — the application that needs DNS records to function (e.g. an email security tool, a website builder)
The flow looks like this:
- The service provider detects your DNS provider by querying the
_domainconnectrecord in your domain’s zone - You are redirected to your DNS provider’s authorization page
- You confirm the changes with one click
- The DNS provider applies a template that creates all necessary records automatically
No manual DNS editing required. The whole process takes seconds instead of minutes.
Which DNS Providers Support Domain Connect?
The following providers have live Domain Connect implementations:
- Cloudflare
- GoDaddy
- IONOS
- NameSilo
- Plesk
- WordPress.com
- Domain Chief
- Glauca Digital
Together, these providers manage a significant share of the global DNS infrastructure. The list is growing — check domainconnect.org for the latest status.
| Provider | Sync API | Async API |
|---|---|---|
| Cloudflare | Yes | Yes |
| GoDaddy | Yes | Yes |
| IONOS | Yes | No |
| NameSilo | Yes | No |
| Plesk | Yes | No |
| WordPress.com | Yes | No |
Prerequisites: What You Need
To use Domain Connect, three conditions must be met:
1. Your DNS provider must support Domain Connect
Your domain’s authoritative DNS must be hosted by one of the providers listed above. You can verify this by checking whether a _domainconnect TXT or CNAME record exists for your domain:
dig TXT _domainconnect.yourdomain.comIf you get a response, your provider supports the protocol.
2. The service provider must have a published template
Domain Connect uses templates that describe which DNS records a service needs. The service provider creates the template and registers it with the DNS provider. Without a matching template, the automatic flow is not available.
3. You must have authorization at your DNS provider
During the Domain Connect flow, you will be redirected to your DNS provider and asked to log in and approve the changes. You need an account with sufficient permissions to modify DNS records for the domain.
Why This Matters for DMARC, SPF and DKIM
Email authentication requires multiple DNS records to work together:
- SPF — a TXT record on your domain listing authorized sending servers
- DKIM — one or more CNAME/TXT records for cryptographic key publication
- DMARC — a TXT record defining your policy and reporting address
Getting all of these right manually is the number one reason why DMARC adoption stalls. Domain Connect can remove this barrier by automating the DNS setup for email security services.
What If Your Provider Doesn’t Support It?
If your DNS provider is not on the list, you will need to configure records manually. The good news: tools like DMARCPulse give you specific, copy-paste-ready recommendations for exactly which records to add — so even without Domain Connect, you know precisely what to do.
Conclusion
Domain Connect is a powerful protocol that makes DNS configuration accessible to everyone. For email security, it can dramatically reduce the friction of setting up DMARC, SPF and DKIM correctly.
Key Takeaways
- Domain Connect automates DNS record creation for email authentication
- It eliminates manual DNS editing errors for SPF, DKIM, and DMARC
- Major providers like Cloudflare, GoDaddy, and IONOS support the protocol
- DMARCPulse uses Domain Connect for one-click DNS setup where supported
- For unsupported providers, DMARCPulse provides copy-ready DNS records
Whether your provider supports it or not — the important thing is that your email authentication is configured properly. DMARCPulse helps you get there, step by step.
