New localization, AI, and design capabilities bring one-to-one marketing and its conversion benefits within reach

Stensul, the AI governance platform for enterprise email marketing, today announced an October product release that helps marketers scale personalized campaigns across markets, languages, and audiences.

Stensul connects the work of AI agents and teams to the brand controls, production workflows, and approvals needed to turn more content and campaign briefs into personalized emails that are ready to launch. The October release’s flagship feature – Localization and Translation at Scale – brings translations, regional adaptations, and personalization variants into one connected workflow.

More than instant high-quality AI-powered translation, the new feature also coordinates reviews and ensures version control across localized and personalized variants. Every version stays on-brand while teams and AI agents remain clear on what’s changed and what’s ready to ship. Customers can use Stensul’s AI translation capability or integrate their own.

“Marketers have long understood the promise of 1:1 marketing: more relevant messages that give each customer a strong reason to act,” said Manlio Carrelli, CEO of Stensul. “The challenge has been producing and managing all the variations that are needed. We’re reducing those barriers so teams can turn personalization ambitions into campaigns that reach more audiences and create more opportunities to convert.”

Three additional October release capabilities help teams scale personalized email production:

• Agentic Email Assembly through MCP: Securely turns campaign briefs into multi-variant, render-tested email code, expanding on Stensul’s existing MCP capabilities. Governance guardrails are applied throughout the process. Teams retain review and approval. Integration to project management and orchestration tools enables this production process to begin automatically, once a brief is created.
• Brand Voice Guardrails: Checks copy against your brand’s voice and tone standards during creation, ensuring a consistent brand experience as teams tailor messages for different audiences.
• Figma-to-Email Production at Scale: Automatically turns full sets of campaign or rebrand designs into reusable email modules. Designers maintain their design system in their preferred tool, while teams and AI agents build with design-approved modules.

The new capabilities are available beginning October 6. Contact Stensul for setup and availability details.
