Are SPF rules displayed correctly to maintain credibility in EU and US?

As an e-commerce business operating internationally, I'm concerned about how our SPF (Sun Protection Factor) rules and claims are displayed to maintain legal compliance and customer trust. The regulations around sunscreen labeling vary significantly between the EU and US markets, and I want to ensure our product information meets both regulatory standards while clearly communicating the level of protection to consumers. What are the best practices for accurately and credibly displaying SPF information across different markets?

TL;DR - Quick Answer

SPF (Sender Policy Framework) rules for email deliverability don't display on your website, but failing email authentication means your marketing emails land in spam - hurting re-engagement of past visitors and reducing repeat conversion rates.

Are SPF Rules Displayed Correctly to Maintain Credibility in EU and US?

SPF (Sender Policy Framework), DKIM, and DMARC are email authentication protocols that affect email deliverability, not website display. Correct setup ensures your marketing emails reach inboxes rather than spam folders - which directly impacts your ability to convert visitors who didn't purchase on first visit.

Email Authentication Stack

  • SPF: Authorizes servers to send email for your domain
  • DKIM: Digital signature proving email wasn't tampered with
  • DMARC: Policy for what happens when SPF/DKIM fail
  • BIMI: Shows brand logo in email clients (builds visual trust)

2024 Google/Yahoo Requirements

  • ✓ SPF or DKIM must pass
  • ✓ DMARC policy required for bulk senders
  • ✓ One-click unsubscribe in headers
  • ✓ Spam rate below 0.1% (Google Postmaster)

Shopify Action: In Shopify Admin go to Settings > Notifications > Email. Ensure your "From" email uses your custom domain (not @shopify.com), and verify SPF/DKIM records in your DNS match what Shopify/Klaviyo/your email platform requires.

Test your setup at mail-tester.com or mxtoolbox.com/emailhealth. A score below 8/10 means emails are likely being filtered to spam for a significant portion of recipients - directly reducing your retargeting conversion rate.
