Email remains one of the highest-ROI channels in digital marketing, and the quality of the email creative directly determines open-to-click conversion. Hellenic Technologies designs and codes HTML email templates that render correctly across all major email clients, load fast on mobile, and are structured to drive recipients towards a clear next action. Our email creative process covers design, HTML/CSS coding, and quality assurance — testing templates across Gmail, Outlook, Apple Mail, and major mobile clients before delivery. We design with dark mode in mind, ensuring emails look intentional rather than broken in dark-mode environments, which now account for a significant share of email opens. Templates are delivered as production-ready HTML files compatible with all major email service providers (Mailchimp, Klaviyo, HubSpot, ActiveCampaign, and others), along with PSD/Figma source files for future editing. Our email creative service includes:
  • HTML email design — Visually designed templates aligned with your brand identity
  • Responsive coding — Clean HTML/CSS that renders correctly across email clients and screen sizes
  • Dark mode optimisation — Intentional dark mode styling to maintain design quality across environments
  • Template types — Newsletter, promotional, transactional, drip sequence, welcome, and re-engagement
  • CTA optimisation — Hierarchical layout design with clear primary and secondary call-to-action structures
  • ESP compatibility — Delivery in formats compatible with all major email service providers
  • QA testing — Multi-client rendering tests via Litmus or Email on Acid before sign-off
