Backstroke’s new L5 Agentic Engine builds fully dynamic, on-brand email campaigns from a simple brief—unlocking flexible layouts, faster production, and data-driven performance.
The L5 system is designed around agentic workflows, rather than predefined templates. Instead of dropping content into a static structure, the engine plans and constructs layouts dynamically based on the brand, the content selected, the intent of the message and sometimes reference HTML.
This shift enables several important capabilities:
1) Flexible, brand-aligned layout formation
The engine starts by forming a structural plan. It decides how many modules an email needs, how products should be arranged, where emphasis should go and how copy should be distributed. Layouts adapt to the shape and goals of the message, rather than forcing the message into a preset framework.
2) Multi-pass reasoning and refinement
Email creation now happens through a series of coordinated steps. The agent interprets campaigns requests, like a creative brief, collections page and/or a set of product description pages. Other agents form a plan, draft an email structure, create and populate content and refine tone and layout to match the brand. This produces consistent results across a wider range of inputs, edge cases and brand preferences.
3) Embedded image generation through AI Content Studio
Backstroke has always offered AI Content Studio (AICS) as a standalone product. Marketers at brands like PSD and Cabana Life use AICS to generate photoshoot quality content to leverage in email campaigns. The new L5 Agentic Engine allows marketers to tap AICS simultaneously during the construction of the campaigns. This means asset requests can be made within the creative brief itself and Backstroke agents will call AICS and inject brand new imagery into the email.
4) A more resilient editing experience
Late-stage changes no longer break the system. Adjusting a headline or promotion triggers the engine to re-evaluate the structure so the final layout still feels coherent. This makes the tool feel closer to working with a flexible design partner, rather than a set of locked components. Backstroke is also rolling out expanded in-app editing capabilities for times when that little human touch is a must to take a campaign from great to perfect.
