Why DMARC is the Gateway to VMC?
DMARC readiness is the first step toward building visible trust with your audience through Verified Mark Certificates. For marketing leaders seeking to boost brand visibility, IT administrators focused on security, and email specialists working to improve deliverability, DMARC readiness is no longer optional, but foundational.
Your email deliverability can jump 5-10% with DMARC implementation. This email authentication protocol protects your brand’s reputation and serves as a key requirement to get a Verified Mark Certificate (VMC).
However, achieving this isn’t automatic, your DMARC record must be set to either “p=quarantine” or “p=reject”, and your SPF and DKIM configurations must align properly.
In this article, we’ll help you understand the key requirements for DMARC readiness to qualify for a Verified Mark Certificate. You’ll also learn how to avoid common pitfalls, monitor your email authentication, and set your domain up for a stronger, more trusted inbox presence.
DMARC Enforcement: The Non-Negotiable for VMC
A Verified Mark Certificate (VMC) requires DMARC at enforcement level as an absolute requirement. Your logo appears in recipients’ inboxes only when DMARC enforcement acts as the gatekeeper, unlike optional email authentication practices.
DMARC enforcement offers three specific options:
- p=quarantine – Unauthenticated emails are sent to spam folders
- p=reject – Unauthenticated emails are blocked entirely from delivery
- p=none – It doesn’t enforce anything but monitors and collects reports on failed email authentication.
To qualify for VMC, your domain’s DMARC policy must be set to either p=quarantine or p=reject, with 100% coverage (pct=100). Partial enforcement falls short of meeting the strict requirements for logo display under BIMI (Brand Indicators for Message Identification).
Organizations often take a strategic path toward enforcement. They start with monitoring mode (p=none) and gather reports without affecting delivery. After identifying legitimate sending sources, they move to quarantine mode. While both p=quarantine and p=reject qualify for VMC, maximum protection comes from advancing to reject mode once the configuration proves reliable.
The recommended path is a phased transition:
Monitor → Quarantine → Full Reject for a secure and disruption-free rollout.
| DMARC Policy | What it Does | Eligible for VMC? |
|---|---|---|
| none | Monitors email authentication but takes no action | No |
| quarantine | Sends suspicious emails to spam/junk folders | Yes |
| reject | Blocks suspicious emails completely | Yes |
Getting DMARC enforcement right early can streamline your journey to a Verified Mark Certificate and save valuable time when inbox visibility matters most.
Why Implement DMARC?
DMARC is one of the most powerful way for protecting your brand’s email domain from cyber threats, especially phishing and spoofing attacks. Organizations should use DMARC to get the following benefits.
-
Protect Brand from Spoofing & Phishing
DMARC helps receive servers authenticate the incoming messages that truly originate from your domain. When it’s properly configured, it blocks unauthorized senders like attackers trying to pretend to be your brand and launch phishing attacks to mislead customers or employees.
-
Improve Email Deliverability
Companies that pass DMARC authentication checks experience higher trust rates from mailbox providers including Gmail, Apple and Yahoo. It increases the chances of landing mail in inbox instead of spam folder, which is crucial for transactional, marketing, and customer communication needs.
-
Strengthen Regulatory and Security Compliance
DMARC supports compliance with industry regulations and email security best practices such as GDPR, PCI DSS, and ISO 27001 that often require protective measures against spoofing and data compromise.
Common Alignment Pitfalls That Break VMC Compliance
When it comes to DMARC compliance, consistency across authentication protocols is key. Both SPF and DKIM must match the domain used in the “From” address of your emails.
Understanding SPF and DKIM Alignment
- SPF Alignment: Your SPF record should include all the IP addresses and domain names that are authorized to send emails on behalf of your domain. For VMC readiness, you must assure that third-party services including Mailchimp, SendGrid and HubSpot are added to your SPF record through proper use of include: mechanisms.
- DKIM Alignment: DKIM uses a digital signature to validate that the email has not been tampered with during transit. To pass DMARC checks, the domain used in the DKIM signature must match the domain visible in the “From” address.
Third-party email platforms don’t always set up SPF and DKIM alignment automatically. This can result in misaligned emails that fail DMARC checks and block your display in inboxes.
To avoid these issues:
- You should add the correct SPF include: statements for all sending platforms.
- Make sure to use custom DKIM selectors where possible, as some platforms use default selectors that might not align with your domain.
- Try using tools like MailTester and Google Toolbox to check your SPF and DKIM alignment before sending emails.
DMARC Monitoring and Reporting
Once DMARC is implemented, reporting becomes one of its most valuable features. DMARC provides you with detailed reports on how your emails are being treated by receiving mail servers. You can identify issues, monitor sending patterns, and fine-tune your authentication policies. These reports help you monitor:
- Sending volumes and IP addresses
- Alignment with SPF and DKIM
- Authentication pass/fail results
- Potential domain spoofing attempts
Types of DMARC Reports
DMARC reports are sent to the email addresses you define in your DNS record via two tags:
- rua= (Aggregate Reports):
These are XML-based daily summaries sent by mailbox providers, offering a broad view of all authentication activity across your domain. They help you identify trends, sending sources, and alignment issues. - ruf= (Forensic Reports):
These are individual failure reports sent in real-time, detailing specific authentication failures. They include message headers and sometimes samples (based on the provider’s policy), helping you investigate anomalies quickly.
To enable DMARC monitoring, you need to publish a DMARC record with a monitoring-only policy (p=none) and specify email addresses to receive both aggregate and forensic reports.
Here’s an example:
v=DMARC1; p=none; rua=mailto:dmarcreports@yourdomain.com; ruf=mailto:dmarcforensics@yourdomain.com
This record allows you to collect daily authentication summaries as well as real-time alerts about individual failures, giving you comprehensive visibility into your domain’s email activity.
The DMARC configuration, published as a DNS TXT record, instructs recipient mail servers. It regulates how to handle communications that do not have SPF and DKIM alignment. These reports, which get back to domain owners, shed insight into message authenticity. It allows for the continuing improvement of email security by identifying authentication successes and possible flaws.
Recommended Monitoring Tools
There are several tools available to help simplify DMARC monitoring:
- Valimail: It’s a great tool to automate and simplify your DMARC implementation along with proper reporting.
- Postmark: Offers robust DMARC monitoring features, making it easy to see which emails are passing or failing authentication.
By monitoring your DMARC reports, you gain confidence in your email security and get a clearer picture of whether you’re ready to transition to a p=reject policy. After all, you don’t want to reject legitimate emails by mistake.
How DMARC Readiness Enables VMC Eligibility?
Verified Mark Certificates connect your domain’s security posture to your brand’s visual identity in email. Your domain needs proper email authentication measures to prove its authenticity and qualify for VMC. However, achieving VMC eligibility requires strict technical compliance at the domain level.
Here’s what your domain must have in place before applying for a VMC:
- DMARC policy must be enforced (quarantine/reject)
- Your domain needs DMARC compliance for at least 30 days before you can apply for VMC
- SPF and DKIM must be set up correctly as the base
- Your logo must be accessible via HTTPS. If it’s not, email clients won’t display it.
Domains that fall short on any of these points often face delays, rejections, or logo display failures across email clients like Gmail, Apple Mail, and Yahoo.

FAQs About DMARC Readiness and VMC Certification
Organizations preparing their domains for VMC eligibility often ask these questions. Here are the answers to common concerns about DMARC implementation and its impact on your VMC journey.
-
Can I get a VMC with DMARC set to p=none?
The short answer is no. You can purchase a VMC without DMARC, but email clients won’t display your logo until DMARC reaches the enforcement level. A policy set to “p=none” only monitors without affecting email delivery, which doesn’t qualify for VMC. Your policy must be either “p=quarantine” or “p=reject” with 100% filtering coverage to display logos through VMC.
-
Why is my marketing tool failing DMARC alignment?
Marketing tools often fail DMARC alignment because their sending infrastructure doesn’t match your domain’s authentication records correctly. This happens when the “From:” address doesn’t line up with the Return-Path (SPF) or the domain in the DKIM signature. The solution is to work with your marketing provider to set up proper authentication methods or domain delegation.
-
How long should I monitor DMARC reports before enforcing?
Your organization’s email ecosystem complexity determines the monitoring period. Experts suggest monitoring for several weeks to find all legitimate senders before enforcement begins. You should collect reports, analyze XML data, and verify that all authorized senders have proper authentication.
-
Does every subdomain need a separate DMARC policy?
Subdomains inherit the parent domain’s DMARC policy by default unless specified otherwise. You have three options to manage subdomains:
- Let subdomains inherit the parent policy (default behavior)
- Set a different policy for all subdomains using the “sp=” tag in the parent domain’s DMARC record
- Create individual DMARC records for specific subdomains that need unique policies
Protecting subdomains matters just as much as the main domain. Attackers often target less-monitored subdomains for their spoofing attempts.
Conclusion
VMC qualification starts with enforcing a proper DMARC policy at 100% coverage. SPF and DKIM configuration create the authentication backbone needed for successful DMARC implementation. Your logo won’t display through VMC if these elements aren’t configured correctly. Common alignment issues can derail your VMC compliance efforts quickly and regular DMARC report monitoring helps catch authentication problems before they affect your email deliverability.
The benefits of DMARC go way beyond logo display as it allows you to get a boost in email security, better deliverability rates, and stronger protection against spoofing attempts. These advantages protect your brand’s reputation and your recipients get better trust signals, and your organization stays protected against sophisticated email-based threats.
