MCP Connector
The Validity Engage MCP connector lets you add Engage to any AI client that supports remote MCP servers—including Claude, ChatGPT, Codex, and Cursor. Pulling from Monitoring and Market Intelligence, you can ask about your deliverability results, the brands on your account, and the competitors you track, right inside your assistant.
Market and Competitive Intelligence
You can now ask Engage questions and view real competitor emails to see what’s working for other brands and how your campaign compares.
Pre-send Intelligence
Test every send before it costs you with new features like LLM-powered spelling and grammar checks, custom rules and properties, and custom send time rules.

Gmail AI Summary Previews
When you send a test email, AI Summary Previews in Litmus show you exactly how Gemini will summarize it—so you know what subscribers are actually reading, not just what you wrote.
Compliance Checks
Litmus Compliance Checks scan every test email for the three most common failure points before you send: a physical mailing address, an unsubscribe link, and the one-click unsubscribe headers Gmail and Yahoo require from bulk senders. Each check passes or fails with specific fix guidance inline.
Accessibility Checks
The redesigned accessibility section in Litmus Previews & QA separates actual WCAG violations from best practices, groups failures by severity, and stops counting best practices as issues. Same 44 checks—now you can actually act on the results.
Email Performance Scorecard
The updated Summary tab in Litmus surfaces QA results from Previews, monitoring status from Email Guardian, and sign-off progress from Proof in a single view. You get one clear read on whether the email is actually ready to send.
Deliverability in Litmus
Litmus now shows inbox, spam, and tab placement data directly inside the tool—so you can see where emails are landing, catch placement issues before they affect your next send, and connect deliverability signals back to individual campaigns.
Validity Engage
Validity Engage uses data from our global inbox network to surface what's working across the market, where risks are emerging, and where your program has room to move—intelligence that sits alongside your existing testing and deliverability workflows.
Typo Correction in BriteVerify
BriteVerify now catches and corrects email address typos at the point of entry. Fewer bad addresses make it onto your list in the first place—which means lower bounce rates and less cleanup later.
