Stensul’s November release helps you use campaign results to shape your next email, personalize messages for more audiences, and bring more campaigns through review and into market.
Every campaign is an opportunity to learn what gives your customers a reason to act. As you personalize across audiences and markets, those learnings can help you make better decisions about the content you send next.
The challenge is putting that knowledge to work. Teams need to connect results to the content behind them, apply what they learn, and get the next round of variations built, checked, and approved. When each addition means more manual work, teams spend more, launch later, or simplify the campaign.
Stensul’s November release helps connect campaign learning with campaign creation. Self-Improving Email leads the release, bringing performance insights into the next build. Additional capabilities make email easier to personalize, check, and prepare for launch.
Self-Improving Email

Put what you learn from each campaign to work in the next one. Self-Improving Email connects email performance to the specific content inside it. AI agents and marketers can use insights from personalized and localized variants to identify content patterns associated with stronger results and apply those learnings to future sends.
This creates a feedback loop between campaign results and campaign creation, helping teams build on what works as their email programs grow. Your team stays in control of review, approval, and what reaches customers.
Self-Improving Email is now in early access. Connect with Stensul to learn more about the early access program.
Inbox optimization

Give each audience a relevant reason to open. Extend personalization beyond the email body with different subject lines and preheaders for existing audience segments within one campaign. Write your own copy, use AI suggestions, or combine the two. Review and approve the variations in your existing workflow, without creating a separate campaign build for every segment.
Compliance pre-send checks

Catch required-content issues while the email is being created.
Compliance pre-send checks monitor for required legal and compliance content, helping teams address issues before they reach reviewers. Routine corrections happen earlier, so teams can send better-prepared work into review and reduce avoidable rounds of feedback.
Shareable render-tested proofs
Make the final email easier to review. Share render-tested proofs across your organization so reviewers can see how the email appears across supported email clients and mobile and desktop formats. Teams can circulate the final proofs for review and retain them as a record of what shipped.
Fast-Start Brand Setup
Start building with your brand from day one. Fast-Start Brand Setup gives customers a governed library of branded email templates and content blocks, along with recommended governance settings. Stensul’s team uses AI to prepare the library around customer-specified requirements and reviews the output. Teams can begin building and testing branded emails right away during onboarding or a rebrand.
Marketing Cloud Next integration
Move approved campaigns into Salesforce for personalization and activation. Stensul’s previously announced Marketing Cloud Next integration is now generally available, connecting campaign production and approval in Stensul with activation in Salesforce Marketing Cloud Next.
Turn campaign learning into more relevant marketing
Together, these capabilities help teams apply what performs, personalize more of the email experience, and reduce the checking and correction work around each launch. The opportunity is to put more of your marketing plan into market—and use what you learn to make the next campaign better.
