Jay Oram, head of dev at ActionRocket, on intra-agency collaboration on email
We create a big email design system, componentize it, and place it inside Taxi For Email or one of the other ones that are out there

Reviewing context
This setup turns custom email production from agency labor into reusable infrastructure. The hard work is building the brand safe modules once, then locking them into a drag and drop editor so local marketing teams can swap copy, images, links, and product availability without touching HTML. That is especially valuable for global brands, where one campaign framework has to be reused across dozens of countries and languages.

In practice, the agency builds a library of approved blocks, like headers, product cards, buttons, and footers, then maps them into an editor such as Taxi For Email. Nespresso used that model so 64 markets could localize language and market specific product details while keeping the core template structure intact.

These tools sit between coding and sending. Parcel is used to build and preview the email code, while Taxi For Email, Stripo, and similar editors let non technical marketers assemble or edit approved components, then push the finished email into an ESP with connectors instead of manual copy and paste.

The business implication is that agencies like ActionRocket can move up the value chain. They get paid for designing the system and for special one off builds, while routine campaign production shifts to the client team. That makes the agency more embedded, because replacing it would mean replacing the underlying module library and workflow.
Email production is heading toward a split model where specialists build the coded system and brand rules, and in house marketers handle day to day assembly inside controlled editors. The winning tools will be the ones that connect modular editing, code preview, and one click ESP publishing into a single workflow.
