MC Lens

Productivity tools for Salesforce Marketing Cloud admins and marketers

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 productivity tools and AI assistance directly inside your Marketing Cloud interface. The free tier works with your existing SFMC session - no setup required. Connect your SFMC account (via a secure OAuth Installed Package) to unlock AI features and cloud sync. Free features (no setup for old instances): - Command Palette (Ctrl+Shift+K) - Fuzzy search across DEs, Journeys, Automations, Lists, and Automation Studio activities. 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 which BUs they exist in, per-BU creation date, and an enterprise-wide status badge. - 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, an in-house SQL formatter, dark mode, Ctrl+Enter to run, a Data Extensions search popover, and a Recent Queries history panel that restores anything you have run in the last 50 sessions. - Email Health - Open any email in Content Builder to see an instant health report: size, link & image counts, spam triggers, alt text audit, and CAN-SPAM check. AI features (require connecting your SFMC account for all new instances): - AI Subject Scorer - Get an AI score (1–100), verdict, and three alternatives for both subject line and preheader. Apply suggested copy directly to the email in SFMC with one click. - AI Email Editor - Edit any email in plain English. Type "make the button red" and see a side-by-side before/after preview before applying. - AI Chat Dashboard - Natural-language access to your SFMC data across all your business units. Ask "what automations errored last night?" or "show me bounces over 5% in the last 7 days." Answers come back as clean data cards, and write actions (pause an automation, update a subject line, draft an email) always require explicit confirmation. - Query Studio AI panel - Explain & Optimize any SQL you write, or chat with AI about your queries with full context. - Cloud-synced Saved Queries - ★ any tab to save it to the cloud, scoped to the current BU or visible across all your orgs. Your saved queries follow you across browsers and machines.

Built for the people who live inside Marketing Cloud every day - admins, email marketers, and campaign managers who need answers fast. Free features run locally in your browser using your existing session. AI features connect to your SFMC account via a secure OAuth Installed Package, so you stay in full control of your tenant. Your data, handled carefully: - Free features run entirely in your browser against SFMC - your session token never leaves your device. - AI features send selected email content (subject, preheader, HTML) and SFMC metadata (such as automation names, data-extension schemas, and send metrics) to our backend and our AI providers (OpenRouter, which routes to OpenAI and Anthropic) to generate suggestions. - Row-level subscriber data is never sent to AI.
