Common Mistakes to Avoid
Common pitfalls come from mismatching build output, QA depth, and workflow expectations across stakeholders and tooling.
Buying validation when full production build is required
Email on Acid is built for rendering QA and screenshot-based diagnostics rather than producing production-ready emails end-to-end. Litmus also centers on validation and testing workflows, so teams needing actual template builds should use VML, AKQA, or Lounge Lizard instead.
Ignoring template scalability and versioning for frequent campaign publishing
Design-only or one-off builds slow iteration when promotions and lifecycle programs need repeated updates. VML and Wunderman Thompson reduce this risk with component-based systems and modular templates designed for scalable campaign and lifecycle production.
Underestimating QA and rendering complexity across major inbox clients
Skipping client-by-client validation can allow broken responsiveness and spacing to reach sends. Email on Acid provides screenshot rendering across Gmail, Outlook, Apple Mail, and mobile clients, and Litmus adds inbox testing combined with rendering previews.
Approaching enterprise governance without a plan for approvals and specs
Complex approvals and insufficient brand input can slow deep custom builds at VML and coordination-heavy engagements at Wunderman Thompson. Publicis Groupe and Dentsu work best when stakeholder governance and personalization logic specs are defined to support consistent global delivery.
