Use custom refinement for bounded edits such as adding a deadline or changing tone; verify names, commitments, numbers, and attachments before sending.
Update — August 12, 2026: This guide now separates one-off draft refinement from Workspace-wide personalization and adds a check for data scope before a user adds files or thread context.
Gmail users can now revise a Help me write draft with a free-form instruction instead of choosing only presets such as Polish, Formalize, or Shorten. A user can ask for a missing detail in the second paragraph, a clearer deadline, or a different tone, then undo or redo the result.
This sounds incremental, but it changes the workflow from one-shot generation to iterative editing. That is usually a better fit for business email—as long as the human remains responsible for the final claim and commitment.
Who receives it
Google says the feature is rolling out through July 20 for Rapid and Scheduled Release domains. It is available across listed Business and Enterprise editions, Google AI consumer plans, Frontline Plus, Google AI Pro for Education, and AI Expanded Access.
Administrators need both Gemini for Workspace in Gmail and Workspace Intelligence access to Gmail enabled. For eligible users, the feature is on by default.
A safer editing pattern
Give the model a narrow transformation rather than asking it to “make this better.” Specify the audience, desired action, tone, and facts that must not change. Then compare the revision with the original before accepting it.
The highest-risk errors in routine email are often mundane: a changed date, an invented attachment, a stronger promise, or a recipient name carried from another thread. Fluency can make those changes easy to miss.
Three prompts that keep the author in control
A useful refinement prompt describes an edit, not a new reality.
- Shorten this to 120 words without changing dates, prices, or commitments.
- Make the requested action and Friday deadline explicit; keep the tone neutral.
- Rewrite for a nontechnical client and preserve every item in the numbered list.
Do not confuse a draft edit with a standing instruction
A refinement instruction applies to the draft in front of the user. Workspace also has a separate personalization feature for standing instructions, and Google says those instructions can carry across eligible products such as Gmail, Docs, Slides, and Chat. Treat a preference that follows the user between products as a different decision from changing one message.
Before adding standing instructions, remove details that do not need to recur and confirm who can use the feature in the organization. Google documents that administrators can restrict Gemini features and the Workspace data Gemini can access. Content owners also retain their existing sharing controls.
Review before inserting, not only before sending
The last review should happen before the draft replaces the original. Compare the recipient, dates, prices, named people, promised actions, and attachment references side by side. If the request relies on another email or a Drive file, confirm that the source is the intended current version rather than assuming the generated summary is authoritative.
For regulated, contractual, medical, legal, financial, or personnel messages, use Help me write as a wording aid only. The accountable author should supply the facts and make the final decision to send; Google similarly cautions that generative features can produce inaccurate or inappropriate suggestions.
