MC Lens

Tired of clicking through endless SFMC menus just to find a Data Extension, check a subscriber, or figure out why an automation failed? MC Lens adds powerful tools directly inside your Marketing Cloud interface — no API credentials, no setup, no developer skills required. It works with your existing SFMC session so you can get to work immediately.

Features:

- Command Palette (Ctrl+Shift+K) — Fuzzy search across DEs, Journeys, Automations, and Lists. Pin bookmarks, copy keys/IDs, view DE field schemas inline, check row counts, and see folder paths without leaving the page.

- Subscriber Lookup (Ctrl+Shift+L) — Full subscriber profile by email or key. List memberships, recent sends, bounces (Hard/Soft/Block), clicks, and activity timeline in one view.

- Cross-BU Subscriber Search — Find a subscriber across all your business units in one click. See per-BU status, creation date, and which BUs they exist in.

- Error Log (Ctrl+Shift+E) — Bounces, delivery failures, job failures, triggered send errors, and import errors in one dashboard with summary cards and filter tabs.

- Send Performance — Sortable send metrics with color-coded thresholds, per-link click drill-down, triggered sends tab, and CSV export.

- Automation Health Monitor — Status overview with run history drill-down and desktop notifications when automations enter error state.

- Engagement Hub — Unsubscribes, complaints, forwards, and forward opt-ins with date range filters and trend spotting.

- Admin Dashboard — Account governance: business units, users, roles, sender profiles, and triggered send definitions with sortable, expandable tables.

- DE Inspector — Contextual side panel in Contact Builder showing data freshness, query dependencies, automation references, and journey entry sources for any DE.

- Dependency Mapper — Impact analysis: see which queries, automations, and journeys reference a Data Extension before you modify or delete it.

- Query Studio Enhancements — A full productivity overlay on SFMC's native Query Studio: persistent query tabs (up to 50), a Data View Explorer with all 30 system data views grouped by category, a Query Library with 11 curated canonical templates (engagement, hygiene, operations, subscribers), an in-house SQL formatter, dark mode, Ctrl+Enter to run, and smart SQL autocomplete that pulls your own Data Extensions and their fields. A Recent Queries history panel restores anything you have run in the last 50 sessions.

- Per-Feature Toggles — Turn individual MC Lens features on or off from the extension popup. Nine toggles across Search & Navigation, Dashboards, and Contextual Tools let you shape MC Lens to fit your workflow without uninstalling anything.
