The Wren Guide

Design once. Send anywhere.

A friendly, illustrated walkthrough for writing a great update — and getting it into Gmail or Outlook with every pixel intact.

WrenHi! I'm Wren. Let's make this easy.

Part 1

Design an update people actually read

A few small choices make the difference between 'skipped' and 'shared'. Here's the Wren way.

One headline, one idea

The serif headline is your hook. Keep it to one clear thought — 'Q3 wins & what's next' beats 'Various updates from the team'.

Write like you talk

Short paragraphs. Active voice. If you'd say it on Slack, say it here. Wren will tidy the grammar — keep the voice.

A hero image earns its keep

Use one if it adds context (a chart, a launch shot, a team photo). Skip it if it's stock filler — white space is a feature.

One CTA, max

Pick the single action that matters: 'Read the doc', 'Book your slot', 'Reply if you can join'. More buttons = fewer clicks.

Pick a template that fits the tone

Editorial for thoughtful updates. Bold for launches. Memo for short FYIs. Try a few — switching is one click.

Preview on mobile

Most of your team will read this on a phone. Toggle Mobile in the preview before you copy — short lines win.

Part 2

Send it from Gmail

The copy-paste trick keeps every font, color, and image. 30 seconds, start to send.

  1. 1

    In Wren, hit Copy HTML

    Open your email in the preview, click the Copy button in the top bar. Wren copies the rendered design — not raw code — so paste keeps the styling.

  2. 2

    Compose a new message in Gmail

    Open mail.google.com, click Compose. Add your recipients and a subject (the one Wren suggested works great).

    Click here to start typing…
  3. 3

    Paste into the message body

    Click into the body and paste (⌘V / Ctrl+V). The full designed email appears inline — headline, hero, CTA, footer, the lot.

    ⌘+Enter
  4. Hit Send

    That's it. Your recipients see exactly what you previewed — in their inbox, from your address.

    Sent — looking gorgeous.

Pro tip: Don't paste into Gmail's "Plain text mode" — switch off the three-dot menu → Plain text mode first. Rich formatting must be on for the design to come through.

Part 3

Send it from Outlook

Outlook strips fancy CSS on paste, so we use a tiny .eml file instead. Same result — full design intact.

  1. 1

    In Wren, click Download .eml

    In the Send dialog, choose the Outlook option. Wren generates an .eml file — that's an email Outlook can open natively.

  2. 2

    Double-click the .eml file

    It opens as a new pre-styled message in Outlook. The headline, images, fonts, and footer are all in place.

  3. Add recipients, then Send

    Fill in To / Cc, double-check the subject, and send. Outlook keeps the design exactly as Wren built it.

    Sent — looking gorgeous.

Heads up: On Outlook Web (outlook.live.com), use File → Import or drag the .eml into the window. On desktop Outlook it just opens — no extra steps.
