Cobalt Blue Feedback Survey Invitation

This is a formal survey invitation email template featuring cobalt blue and bright cyan as its primary color scheme, for product feedback collection, user reminders, and feature experience research scenarios. The template uses a 600-pixel email canvas, with an eyebrow, main title, and subtitle at the top to establish a clear reading entry point. The middle body area supports Markdown HTML, and the bottom sequentially places a closing greeting, signature, and external link button. The overall color palette includes cobalt blue, bright cyan, warm white, and coral orange, creating a professional and approachable style. Long body content maintains visual continuity through vertical extension of the main background. The template retains placeholders for title, eyebrow, subtitle, body, greeting, signature, external links, and theme footer, facilitating batch editing and automatic translation, helping recipients quickly understand the benefits and complete the next action.
