# Your writing style Learned from the mail you send.

Mail you send from the composer builds a running profile of how you write, and drafts, rewrites and subject lines are asked to match it.

In short

## What is a writing style profile?

A writing style profile measures how somebody writes: sentence length, vocabulary, punctuation, formality and how they open and close. Given to a language model, it pulls the text toward the writer's voice.

How it works

## Measured from what you send

A message you send from the composer is read for 52 measures, from sentence length and lexical density to how you open and close.

## Drafts that start from you

Write this for me, Rewrite and the subject suggestion all read the profile, and drafts are asked to reuse your usual greeting and sign-off.

## One profile for the workspace

Everybody who sends from a workspace writes into the same profile and drafts from it. If only you send, it is simply yours.

## What gets measured

Eight of the 52, as the profile names them.

What you get

## In the product today

Updates as you send

Sends fold into running averages, with nothing to set up.

Templates stay out

A message sent from a template is never measured.

No profile yet

Until someone in the workspace sends, drafts are written without one.

An editable prompt

The Compose prompt that applies it sits under Prompts.

Good practice

## Getting the most out of it

1. 01
   
   Send your own first
   
   Early sends move the averages most, so send some real replies before leaning on drafts.
2. 02
   
   Edit before sending
   
   A draft sent unedited is measured like your own mail, so make it yours first.
3. 03
   
   Name the tone
   
   Need another register for one message? Say so in your note and the profile gives way.
