Summary
Setting up DMARC for Shopify is crucial for email deliverability and brand protection. Shopify advises users to implement DMARC, often through their DNS providers. While the basic setup is generally straightforward, a critical point of contention arises with the rua tag, which is used to send aggregate DMARC reports. Best practices strongly recommend against directing these reports to general support email addresses due to the high volume and technical nature of the data, which can overwhelm inboxes and lead to confusion.
Key findings
- Importance of DMARC: DMARC is essential for Shopify merchants to enhance email security, prevent spoofing, and ensure transactional and marketing emails land in the inbox, not spam folders. It works alongside SPF and DKIM for comprehensive email authentication, as detailed in our guide on implementing DKIM, SPF, and DMARC.
- Shopify's role: Shopify actively encourages DMARC setup, providing documentation for domain authentication and DMARC record creation. This aligns with broader industry requirements from major mailbox providers.
- Common setup issues: A common issue involves incorrect configuration of the rua tag, which is often mistakenly set to a merchant's primary support email address by third-party DNS providers or misinterpretation of instructions.
- Impact of incorrect rua tag: Directing DMARC aggregate reports (RUAs) to a general inbox can lead to a deluge of XML files, making it impossible to manage legitimate support queries and process the valuable DMARC data effectively. These reports are meant for automated processing, not human review.
- Authentication for Shopify: Shopify requires merchants to authenticate their email domain (often through a CNAME record for DKIM) and set up SPF and DMARC records to comply with new sender requirements from Google and Yahoo. More details on DMARC tags can be found in our list of DMARC tags and their meanings.
Key considerations
- Dedicated DMARC reporting address: Always set the rua tag to a dedicated email address or, ideally, a specialized DMARC reporting service. This prevents report spam and allows for proper analysis of DMARC data.
- Avoid operational email addresses: Never use an email address that is critical for business operations (like customer support or sales) for DMARC reports. This protects it from being swamped by XML reports, which can disrupt critical communications.
- Understanding DMARC reports: Merchants should understand what DMARC reports are and how to interpret them. This knowledge is key to leveraging DMARC for improved deliverability and protecting their brand from spoofing attempts.
- Policy progression: Start with a p=none DMARC policy to monitor email activity without affecting delivery. Once confident in your authentication setup, you can gradually move to p=quarantine or p=reject for stronger protection. More information on policy can be found in Shopify’s help documentation on setting up DMARC.
What email marketers say
Email marketers using Shopify frequently encounter DMARC setup challenges, particularly around the rua tag. While they understand the importance of DMARC for deliverability and brand reputation, the technical intricacies, especially managing aggregate reports, can lead to frustration. The consensus is that DMARC is vital, but its implementation needs to be streamlined and clearly communicated to prevent common pitfalls that lead to unintended consequences, such as overwhelming support inboxes with XML reports.
Key opinions
- DMARC is a necessity: Marketers universally agree that DMARC is no longer optional, especially with new sender requirements from major mailbox providers. It is seen as critical for maintaining good email deliverability and ensuring emails reach customer inboxes rather than spam folders.
- Confusing rua advice: Many marketers report being advised (sometimes by DNS providers or even indirectly by platforms) to set their rua tag to a general support email, leading to significant problems.
- Overwhelmed inboxes: Directing DMARC reports to an active support inbox results in it being flooded with technical XML data, making it difficult to find and respond to actual customer inquiries. This is a common deliverability issue that requires attention.
- Lack of understanding: There's a general lack of understanding among some users about what DMARC reports are and how to properly handle them, leading to frustration and mislabeling them as spam themselves. Understanding these reports is key to fixing emails going to spam.
- Need for clear guidance: Marketers seek clearer, more actionable advice from email service providers (ESPs) and platforms like Shopify on DMARC setup, especially regarding the appropriate handling of rua reports.
Key considerations
- Utilize DMARC reporting services: Marketers should strongly consider using a dedicated DMARC reporting service to automatically process and visualize the aggregate reports. This makes the data actionable and prevents inbox overload.
- Verify DNS settings: It's important to verify that DMARC, SPF, and DKIM records are correctly published in DNS and aligned with all sending sources, including Shopify and any other third-party ESPs. This is part of the best practices for email authentication.
- Educate on DMARC purpose: As DMARC adoption grows, there's a need for better education for end-users (merchants) about the purpose of DMARC reports and why they should not be sent to customer-facing inboxes. This helps prevent self-inflicted spam.
- Proactive monitoring: Even after initial setup, continuous monitoring of DMARC reports is essential to identify any unauthorized sending or legitimate sending that is failing authentication. This is key to long-term email deliverabilitybest practices for Shopify.
Marketer view
An email marketer from Email Geeks notes that they are observing a trend where many individuals are now setting up DMARC as advised by their email platforms. While this is positive overall, the incorrect setup of the rua tag, particularly with Shopify users, is leading to issues. They report that Shopify users are often advised to direct aggregate reports to the support email address of the sender or merchant. If this advice is indeed coming from Shopify, it is considered very problematic.
Marketer view
A marketer from LaunchTip emphasizes that for Shopify merchants, setting up DMARC significantly improves email security and deliverability. This ensures emails are not marked as spam, helping to build trust and strengthen brand reputation. Proper DMARC configuration is essential for transactional and marketing emails to reach their intended recipients.
What the experts say
Experts in email deliverability emphasize that while Shopify's push for DMARC adoption is positive, the specific guidance regarding the rua tag needs refinement. They highlight the impracticality of directing voluminous aggregate reports to human-monitored inboxes. The core message from experts is to ensure DMARC is set up correctly, with proper handling of reports, to truly leverage its benefits for security and deliverability without creating new operational headaches.
Key opinions
- Shopify's DMARC encouragement: Experts acknowledge that Shopify is actively providing instructions for DMARC setup, demonstrating their commitment to stronger email authentication standards for their merchants. This is generally a positive step for the ecosystem.
- Misinformation from DNS providers: The issue of directing rua reports to support emails appears to stem more from third-party DNS providers or general misunderstandings rather than explicit, incorrect instructions from Shopify itself. This underscores the fragmented nature of email setup advice.
- Overwhelming report volume: DMARC aggregate reports are generated frequently and can be very numerous, making it impractical for human inboxes to process them. This volume necessitates automated solutions for report ingestion and analysis. Such solutions can help monitor DMARC records and reporting.
- Risk of self-inflicted spam: When DMARC reports are sent to inappropriate addresses, it creates a scenario where the company itself feels spammed by its own authentication data, diverting resources and causing confusion. This issue often comes from a lack of technical knowledge.
- The need for a DMARC policy: Experts recommend starting with a p=none policy and gradually progressing to more restrictive policies like p=quarantine or p=reject once data confidence is achieved, as discussed in our guide on safely transitioning DMARC policy.
Key considerations
- Proper rua tag configuration: It is crucial to set the rua tag to an address specifically designated for DMARC aggregate reports, ideally managed by a DMARC monitoring service. This ensures the data is processed efficiently.
- Alignment with all senders: Ensure that all email sending platforms (including Shopify, marketing automation platforms, and transactional email services) are properly configured for SPF and DKIM alignment, as DMARC relies on these foundational protocols. This is particularly important when setting up DMARC with multiple email senders.
- Domain reputation management: Proper DMARC implementation contributes significantly to a positive domain reputation, helping avoid blocklists and ensuring higher inbox placement rates. Monitoring DMARC reports is a key part of managing this reputation.
- Educating the broader ecosystem: There's an ongoing need for better education not just for end-users, but also for DNS providers and other service entities that provide DMARC setup instructions to ensure they promote best practices, especially concerning the rua tag.
Expert view
An email deliverability expert from Email Geeks suggests that some days, there simply isn't enough coffee to deal with the complexities and misunderstandings surrounding email deliverability, particularly when it comes to DMARC implementation. This highlights the ongoing challenges of educating users and ensuring correct configurations in the field.
Expert view
An email deliverability expert from Word to the Wise notes that proper DMARC implementation is essential for brand protection, helping organizations prevent their domains from being used for phishing and spoofing attacks. The expert emphasizes that accurate DMARC records act as a strong deterrent against malicious actors, safeguarding both the brand's reputation and its recipients.
What the documentation says
Official documentation for DMARC, including standards and platform-specific guides, uniformly emphasizes the technical nature of DMARC reports. It highlights that aggregate reports (RUAs) are XML formatted and intended for automated processing, not direct human consumption. Documentation from platforms like Shopify typically guides users through adding the necessary DNS records (SPF, DKIM, DMARC) to authenticate their domains, aligning with broader internet standards for email security.
Key findings
- DMARC record syntax: DMARC records are published as TXT records in the DNS, beginning with v=DMARC1 and including various tags such as p (policy) and rua (aggregate report URI). A detailed overview of these can be found in our guide to DMARC tags.
- Purpose of rua reports: Aggregate reports (RUAs) are XML documents containing summarized data about email authentication results. They are sent by receiving mail servers to the email address specified in the rua tag, indicating which emails passed or failed DMARC, SPF, and DKIM checks.
- Shopify's DMARC instructions: Shopify's official documentation outlines the process for connecting a third-party domain, which includes adding necessary DNS records like CNAME for DKIM authentication and TXT records for SPF and DMARC. This ensures emails sent from Shopify are properly authenticated.
- Gradual policy rollout: Official DMARC best practices advise starting with a p=none policy to monitor email streams without affecting delivery. Only after thorough analysis of reports should the policy be advanced to p=quarantine or p=reject. Our guide on simple DMARC examples explains this process.
Key considerations
- Automated report processing: Given the format and volume of DMARC aggregate reports, it is imperative to use automated tools or a dedicated DMARC reporting service to parse and interpret the data. Sending these reports to a standard inbox will lead to clutter and render the data unusable.
- Domain alignment: For DMARC to pass, emails must pass SPF or DKIM authentication, and the domain in the From header (RFC5322.From) must align with the domain authenticated by SPF (RFC5321.MailFrom) or DKIM (d= domain). Shopify merchants must ensure their sending domains are correctly aligned. This ensures that the emails aren't flagged by a DMARC checker tool.
- Consistent sender practices: All email sending platforms used by a Shopify merchant (e.g., transactional email providers, marketing platforms) should be configured to send emails that comply with the domain's DMARC policy. Inconsistent authentication can lead to legitimate emails being rejected or quarantined.
- Monitoring and adjustment: Regular review of DMARC reports is essential to identify any unauthorized use of your domain or issues with legitimate email streams. The DMARC policy can then be adjusted as needed to balance security and deliverability.
Technical article
Documentation from the DMARC.org standard states that DMARC enables senders to indicate that their emails are protected by SPF and/or DKIM, and to tell receivers what to do if neither of those authentication methods passes the DMARC alignment checks. This includes policies for reporting the results back to the sender, which is fundamental to its functionality.
Technical article
RFC 7489, the DMARC specification, defines the rua tag as a URI (Uniform Resource Identifier) for sending DMARC aggregate feedback reports. It specifies that these reports should be sent to an address capable of receiving and processing XML-formatted data, implicitly advising against general-purpose inboxes.
