(01) Why use Rainbrand

A coding agent can animate a banner, but without the brand's fonts, logos and product images it has to guess. Rainbrand gives it a Brief for the banner, with the brand's fonts, logos, colours and imagery.

The Brief is ready. I'll make a short product tour with one beat each for cards, expenses, approvals and reporting, set in Lausanne with the wordmark.

I rendered it with the skill's script and checked the frames against the Brief on light and dark backgrounds. I've opened signature.gif so you can see it move. Setup steps for Gmail, Apple Mail and Outlook are below.

Email signature GIF FAQ

Asked,
answered.

All FAQs

What do I need to make a signature GIF?

A coding agent that can run Node.js, such as Claude Code, connected to Rainbrand through MCP, and a ready brand or a website to create one. Then point the agent at rainbrand.com/signature. Connect Rainbrand to your agent.

What does the Brief add to the banner?

The Brief selects the fonts, logos, colours and imagery for the banner. Ramp's supplied Lausanne, the wordmark and four product screens. In Rainbrand's own banner, its voice guidance became the numbered labels and the [READY] chip. How Briefs work.

Can I choose what the banner shows?

Yes. Describe it in your prompt. Otherwise your agent picks the idea that suits the brand, usually a short product tour with one beat for each thing the company does, and writes the copy in the brand's voice using claims from the Brief or the company's own site.

Will it work in my email client?

The skill gives setup steps for Gmail, Apple Mail and Outlook. Classic desktop Outlook shows only the first frame, so the loop starts on a finished still. The banners in the guide came out at 200 to 310 KB at 600 × 200, with a sharper 2× file alongside.

How is the banner checked?

The render script writes sheets of the loop, its transitions and the first frame on light and dark backgrounds, and your agent reviews them against the Brief. The skill also asks Rainbrand for a Review of the first frame. Before you use it, send yourself a test email and check it on your phone and in the email clients your recipients use.
