You've seen people ask ChatGPT for a website header image. Here's how in Copilot: choose Design a banner in Create and describe it. Your brand kit applies if your company set one up.

A common situation (composite)

Every newsletter uses the same header.
Nobody notices it anymore.
I want a fresh one for this month's theme.

What you get

Data: the theme and headline, plus your brand colors.
Does: drafts a wide banner design.
Output: a banner image to download.
How often: monthly or per campaign.

Before you start

Needs: Microsoft 365 Copilot Chat with your work account (a Microsoft 365 Copilot license gives steadier quality). Not sure what you have? Start here.
Where: Copilot app, Design a banner.
Access: Copilot only uses content you already have permission to open. Use only information your company allows in Copilot.

The steps

Open Create and choose Design a banner.
Paste the prompt.
Choose Brand and color if your company has a brand kit.
Generate, refine, then Save and copy or download.

Copy this prompt

Prompt: email header

Wide email header banner for our [month] newsletter, theme "[theme]". Clean flat illustration of [motif] on the right, [brand color] background, headline "[headline]" on the left in bold sans-serif, lots of breathing room, professional and warm.

What a good result looks like

Text is spelled right and stays clear of the edges once cropped.

If a feature is missing

If your tool needs an exact pixel size, download the image and crop it there.

Make it smarter

Keep a short "What it got wrong" note. Paste it above the prompt next time, like "Don't invent dates".

Not sure what to ask? Copy the quick note for your Copilot admin.
