Email Content Translation agent
Email Content Translation is an agent in Mark (Optimizely Agent Platform). It translates a full email in Optimizely Campaign into a target language. The translation covers the body, subject line, preview text, and image alt-text. The agent displays the original and translation side-by-side in a canvas.
- Challenge – Manually translating email content while keeping accuracy, cultural relevance, and brand voice across languages is slow and error-prone.
- Agent outcome – The agent retrieves the full email and translates the body, subject, preview, and alt-text. It then shows the original and translation side-by-side.
- Value – Faster, consistent email translation that preserves accuracy, cultural relevance, and brand voice.
