June 2026 releases: Stensul MCP, Accessibility QA, and more

june release

Every CMO we talk to is carrying the same question right now. How do you actually adopt AI across a marketing organization without losing control of what ships?

More tools, more agents, more people generating drafts — that part is solved. Getting that work on-brand, compliant, accessible, and approved before it reaches a customer is where enterprise marketing organizations are getting stuck. The volume of creation goes up. The review process breaks under it.

Stensul was built for that problem. AI just made it urgent for everyone.

This month’s releases are proof of what the solution looks like in practice. Each one moves governance into the places where AI-assisted work is now happening — the tools where agents create, the builder where accessibility used to be caught too late, the dynamic variants where governance most often falls behind, and the regulated environments where AI features were previously locked out entirely.

 

Here’s what we shipped.

  • Stensul MCP Server Early Access Program — Open today: The governance layer is now callable by AI agents, from any tool a marketing team is already using.
  • Accessibility QA Check — Beta: Real-time WCAG 2.1 AA checks, built into the builder, before send. 
  • Bring Your Own LLM — Beta: Regulated customers can now run Stensul’s AI features on their own approved LLM, inside their existing compliance environment.
  • Dynamic Content Review & Approval — Now available: Review every variant of a dynamic email in one place, without screenshots, PDFs, or a separate proofing tool.

Stensul MCP: the governance layer, now callable

Stensul recently announced the Stensul MCP Server Early Access Program, giving enterprise marketing teams a way to bring Stensul governance to more places where AI-assisted creation is happening, starting with email. 

The significance isn’t just the connection, but what sits behind it.

A marketer drafts in Claude. A designer starts from a brief in Figma. A business user asks an agent to generate a campaign variant. All of that creation now has real leverage — and a real governance problem. In enterprise marketing, work has to meet standards before it reaches the customer. Brand rules. Compliance. Accessibility. Approval paths. And more creation doesn’t help if more of it gets stuck in review, sent back for rework, or never ships at all.

Stensul MCP makes that possible. AI agents operating in any MCP-connected tool can now create inside Stensul’s governance — the same templates, brand rules, compliance checks, and approval workflows your team already trusts, regardless of where the work started. AI-assisted creation happens inside the controls required to ship, not around them.

The Early Access Program is open today. If your team is building AI into your marketing workflow and wants to help define what governed AI creation looks like in practice, request access here.

Accessibility QA Check, a Governance Agent

Accessibility has always been part of enterprise marketing governance. Until now, enforcement has happened late — in spreadsheets, in post-export point tools, or in legal review when something had already shipped. That’s not governance. That’s cleanup.

Accessibility QA Check is a Governance Agent that runs inside the builder and checks emails against Web Content Accessibility Guidelines (WCAG) 2.1 standards in real time as they’re being created. Checks including color contrast and alt text get flagged on the canvas before the email ships — automatically, every time, regardless of who built it or when.

The governance moves to where the work happens, not where it ends up. For regulated industries facing ADA enforcement, EAA compliance, or procurement requirements gating renewals on accessibility, that shift matters.

Accessibility QA Check is available for all customers in the Stensul platform.

Bring Your Own LLM

In case you missed it, we rolled out BYO LLM in April. For many regulated marketing teams in financial services, healthcare, and life sciences, AI can only run through models their organization has already vetted and approved. With BYO LLM, customers connect their own approved LLM (OpenAI GPT, Anthropic Claude, or Google Gemini via major cloud providers) directly to Stensul’s governed templates and workflows. Every AI request routes through the customer’s managed environment, under their existing contracts and controls, and never leaves it.

The creation experience is identical. The only thing that changes is which AI is doing the generating.

BYO LLM is now available in beta.

Dynamic Content Review & Approval

The new dynamic content review and approval experience is available for customers. Reviewers can now preview every segment combination of a dynamic email, comment in context, and approve — all without leaving Stensul.

Dynamic content is where governance is notoriously difficult to maintain. When an email has multiple versions for multiple audiences, review and approval processes struggle to keep up — and governance gaps tend to show up there first.

This brings governance into every step of the review process regardless of how many variants an email has. Every combination is visible, every comment is tied to the right version, and approval accounts for the full picture.

At Salesforce Connections, we’ll be on the ground doing live demos of Stensul MCP, and more. Get an exclusive look at what governed AI creation looks like for your team at Booth #411, or sign up for a custom demo here.

In summary

These four releases share a single logic. AI changes who and what can create. Stensul governs what can ship. For enterprise marketing teams that can’t afford to lose control of brand, compliance, or quality when they scale creation — that’s what this month is about.

If your marketing team still waits in line for “Web”, it’s time to break free.
