How to design an email banner and header

Designing an email banner that looks sharp across every inbox typically means juggling image editors, testing responsive layouts, and hand-tuning spacing for Outlook, Gmail, and Apple Mail. Morphic's email banner workflow generates campaign-ready headers in minutes, giving you a polished visual that stays on-brand and renders correctly at any screen size.

Whether you're launching a product, promoting a sale, or sending a weekly newsletter, the workflow handles layout, typography, and styling so you can focus on copy and strategy.

What is an email banner?

An email banner is the hero image displayed at the top of a marketing email or newsletter. It sets the visual tone, reinforces brand identity, and guides readers into the body content. A strong banner combines a clear headline, concise supporting text, and a design style that matches the campaign's purpose.

Provide your headline, subtitle, and design preferences, then run the workflow. Morphic composes the layout, applies your chosen style, and exports a banner optimized for major email clients. The result is a production-ready image that maintains visual hierarchy from desktop to mobile.

1.

Enter your headline text

Open the "Email banner" workflow. In the "Headline text" step, type the main headline for your banner. The example shows "Introducing Morphic." Keep it concise and action-oriented — this is the first text readers see.

Add your subtitle text

In the "Subtitle text" step, enter an optional subtitle, tagline, or description line. The example shows "A new era of storytelling." This provides context or a secondary call to action.

Upload a brand image

In the "Brand image" step, browse the gallery or upload an image that represents your brand — a logo, product photo, or visual identity reference. This image guides the visual styling of the generated banner.
