Sender Guardian
2025 Bulk-Sender Rules Guide

Stop "via shopifyemail" from eroding your brand.

The Revenue Protection concierge for Shopify + Klaviyo merchants. We fix SPF, DKIM, and DMARC so Gmail, Yahoo, and Outlook stop blocking your revenue.

If customers never see your flows or order emails, they can’t buy. Broken authentication is a revenue leak, not just a “deliverability issue.”

We diagnose the root cause and deliver a step-by-step remediation plan your team can execute immediately.

100% money-back if we can’t identify any material authentication or deliverability issues.

Why this suddenly matters

Gmail, Yahoo, and now Outlook.com enforce strict rules for bulk senders (5,000+ messages per day). When authentication is broken or misaligned, you face:

  • Brand dilution: Shopify rewrites your From to [email protected].
  • Outlook blocking: Immediate 5.7.515 rejection errors (your emails are deleted before they even reach the junk folder) on Outlook.com / Hotmail / Live.
  • Revenue leaks: Campaigns and flows silently landing in spam or never being delivered.

Safety, Privacy & Protocols

Strict Delegated Access

We never ask for your passwords. We use registrar delegation and "collaborator" accounts for Shopify/Klaviyo to ensure all changes are logged and reversible.

Privacy-First Architecture

We operate on metadata only. We strictly disable DMARC Forensic (RUF) reporting to ensure we never receive or store your customers' PII or message bodies.
