Branded Email — AI-designed, on-brand emails

Note

Branded Email is one capability of @bridge Compose — the AI-writing panel in the Thunderbird compose window. Compose also improves, rewrites, retones and translates plain-text drafts; this page covers the branded HTML email it can produce.

Branded Email turns a plain request into a polished, on-brand HTML email — no design tool, no HTML, no hunting for a template to copy-paste. Tell your AI what you need (“invoice Acme for 10 hours of design at $120”), and @bridge designs it: headings, columns, tables, charts, status badges, callouts — all styled by your brand theme, composed and sent right from Thunderbird, on your machine.

Your AI writes the content — @bridge builds the email

Here’s the important part: your AI never hand-codes the HTML. Large language models are unreliable at email HTML — the markup is fiddly and what they produce rarely survives Gmail or Outlook. So @bridge splits the job:

• Your AI does what it’s good at — the words and the structure. It hands @bridge a simple content outline (a heading here, a table there, this callout), not raw HTML.
• @bridge builds the email — it turns that outline into email-safe, on-brand HTML: your colours and wordmark, tables that render in every client, charts, responsive columns. Deterministically, every time.

You get a polished, consistent email — not a brittle one-off the model guessed its way through.

What you can make

Start from a ready template — just say which one, fill in the blanks, send.

Invoice Bill-to details, a line-item table that totals itself, payment terms.

Newsletter A few stories, each with a “Read more”, wrapped in your brand.

Marketing A hero benefit, a feature grid, and one clear call to action.

Proposal Intro, scope callout, priced deliverables table, accept button.

Project update Headline status, risks, a delivery bar, per-workstream cards.

Cold outreach Personal, un-branded, one easy ask.

Follow-up A friendly nudge that makes the next step obvious.

Meeting invite When, where, who, the agenda, and add-to-calendar.

Welcome A warm hello and the first few steps to get going.

Feedback request A short, sincere ask with a one-tap link.

Made one you love? On Pro and Enterprise you can save your own templates and reuse the layout anytime.

Why it’s different

On your brand, automatically

Every email uses your saved theme — colours, wordmark, tagline — so it looks like you, not a generic template. Set up your brand theme →

You describe, AI designs

No drag-and-drop builder and no HTML. Plain language in, a structured, email-safe layout out.

Real building blocks

Headings, columns, tables with totals, charts, progress bars, status badges, callouts — the things real business emails need.

Local & private

Composed on your machine in Thunderbird; @bridge never routes your mail through its own servers.

Create one in seconds

The fastest way is to ask. In Thunderbird (or any connected AI), say “draft an invoice to Acme for 10 hours at $120” — @bridge starts from the invoice template, already on your brand.

Prefer the command line?

• atbridge compose templates list — see them all
• atbridge compose templates show invoice — get a ready spec to fill in
• atbridge compose render --spec your-invoice.json — render + open it in Thunderbird

More templates are coming in next releases.
