Addressing DMARC failures when using Trustpilot email invitations with a custom domain requires a multifaceted approach. Begin by verifying if the return path is aligned and understanding whether Trustpilot is using its own domain. Experts suggest that DMARC failures often stem from SPF alignment issues due to discrepancies between the 'envelope from' and 'header from' domains. Review and correct SPF and DKIM records, utilizing a DMARC record checker for validation. Consider sending Trustpilot invitations from a dedicated subdomain to isolate DMARC failures and maintain the main domain's reputation. Analyze email headers, particularly the Authentication-Results, to pinpoint SPF or DKIM failures. Other recommendations include contacting Trustpilot support, using a dedicated IP address, whitelisting Trustpilot's sending domains (with caution), and implementing feedback loops. Starting with a relaxed DMARC policy (p=none) can help monitor email flow before enforcing stricter policies. Most Trustpilot users don't use custom domain settings, potentially impacting deliverability.
10 marketer opinions
When encountering DMARC failures with Trustpilot email invitations using a custom domain, several strategies can be employed. A common approach involves using a dedicated subdomain for Trustpilot emails to isolate any DMARC-related issues. Analyzing email headers to pinpoint SPF or DKIM failures is crucial, followed by ensuring proper SPF record configuration or exploring DKIM signing with Trustpilot. Contacting Trustpilot support may reveal tailored solutions, especially for Enterprise clients. Other recommendations include whitelisting Trustpilot's sending domains (though it reduces DMARC effectiveness), creating a relaxed DMARC policy (p=none) for monitoring, and setting up feedback loops to track recipient complaints. Additionally, using a dedicated IP address for Trustpilot emails can simplify SPF/DKIM configuration.

Email marketer from Email Geeks explains that they discovered most Trustpilot users don't use the 'Custom Domain' setting, resulting in emails being sent from Trustpilot's domain. The company is using their own domain, which is causing issues because TrustPilot only supports SPF records. They will revert to sending invitation emails from Trustpilot's domain until they support DMARC setup.

When addressing DMARC failures with Trustpilot email invitations using a custom domain, experts highlight key aspects related to Trustpilot's email infrastructure and configuration. It's crucial to understand whether Trustpilot sends emails using their own domain, similar to services like PayPal, which would restrict custom SPF, DKIM, or DMARC setup. Despite utilizing platforms like Twilio/Sendgrid that support DKIM/DMARC, Trustpilot might be making a business decision not to fully implement these security measures. A significant cause of DMARC failures is often SPF alignment issues stemming from discrepancies between the 'envelope from' and 'header from' domains. Therefore, a careful review of SPF records and exploring DKIM signing options (if available from Trustpilot) are essential.
Expert view
Expert from Email Geeks questions whether Trustpilot uses their own domain for sending emails like PayPal, making it impossible for users to set up SPF, DKIM, or DMARC. She also shares her own email headers which show that Trustpilot uses dkim and dmarc.

Expert from Word to the Wise explains that when using third-party senders like Trustpilot, DMARC failures often stem from SPF alignment issues because the 'envelope from' domain doesn't match the 'header from' domain. They recommend carefully reviewing SPF records and considering DKIM signing options if available from Trustpilot.

When addressing DMARC failures with Trustpilot email invitations using a custom domain, documentation emphasizes the importance of correct SPF and DKIM setup. DMARC failures often stem from SPF or DKIM alignment issues, where the 'header from' domain doesn't match the 'envelope from' domain (for SPF) or the DKIM signature domain (for DKIM). Crucially, analyzing email headers, particularly the `Authentication-Results` header, helps pinpoint whether SPF or DKIM is failing and why, aiding in the identification and correction of misconfigurations.
Technical article
Documentation from DMARC Analyzer explains that DMARC failures typically occur due to SPF or DKIM alignment issues. If SPF passes but doesn't align (the 'header from' domain doesn't match the 'envelope from' domain), or if DKIM fails, DMARC will fail. They recommend checking SPF and DKIM records and alignment.

Documentation from EasyDMARC explains that DMARC alignment is crucial. For SPF to align, the `header from` address must match the `envelope from` address. For DKIM to align, the domain in the `d=domain.com` tag of the DKIM signature must match the `header from` address. They suggest ensuring these alignments for Trustpilot emails.
