How to Build a Proofread-and-Send Writing Automation on Mac

The short answer

A safe proofread-and-send automation should automate the writing, not the decision to send. The useful sequence is: draft naturally, run a minimal proofread, rewrite for the recipient if needed, verify names and details, then click Send yourself.

Echoo turns those repeated editing steps into commands that run inside Apple Mail, Outlook, Gmail, and other Mac apps. You avoid the copy-paste loop without giving an AI permission to send an unchecked message.

Why proofreading and rewriting should be separate

Proofreading and editing solve different problems. A proofread should correct grammar, spelling, punctuation, and syntax with the smallest possible changes. A rewrite may change tone, structure, or length for an audience.

Combining both in one vague prompt makes the result harder to audit. A cleaner workflow is:

• Proofread first. Remove objective errors while preserving meaning.
• Rewrite second, only if needed. Adjust tone for a client, teammate, or executive.
• Proofread again lightly. Catch errors introduced by the rewrite.
• Review facts and send manually. Check recipients, names, dates, links, attachments, and the requested action.

See proofreading vs editing (opens in new tab) for the boundary between the two passes.

Step 1: save a strict proofread command

A useful proofreading instruction is conservative:

Correct spelling, grammar, punctuation, and syntax. Preserve meaning, tone, voice, names, dates, numbers, links, quoted text, structure, and formatting. Do not add or remove information. Return only the corrected text.

Echoo’s prompts are editable, so you can add company terms, product names, or formatting rules. For confidential email, route the command through a local model with Ollama.

Step 2: save audience-specific rewrites

One “make this better” command is too broad. Save separate commands for the contexts you actually repeat:

• Client email: warm, clear, accountable, and concise
• Executive update: direct, brief, and decision-oriented
• Team message: conversational and easy to scan
• Customer support: empathetic, specific, and action-focused

The built-in Professional Tone command is a starting point. Its rules preserve facts and avoid adding context that was not in the draft.

Step 3: connect the sequence

Use the Rewrite Then Send an Email workflow (opens in new tab) as the recipe. Draft in your inbox, select the text, run the appropriate rewrite, then apply the strict proofread command.

If you prefer speaking first, use Dictate Then Proofread (opens in new tab). Echoo captures the draft locally, then cleans punctuation, capitalization, and speech artifacts before you review it.

Step 4: keep the final approval human

Do not automate Send. Models can alter a date, drop a qualification, misunderstand a name, or produce confident language that is stronger than you intended. The last check should cover:

• To, CC, and BCC
• names and pronouns
• dates, times, prices, and quantities
• links and promised attachments
• the exact call to action
• whether the tone fits the relationship

This review takes seconds and protects the part that matters most: what leaves your account under your name.

Try the workflow

Start with the proofread email guide (opens in new tab), then adapt the workflow to your common recipients. If you are comparing passive grammar suggestions with shortcut-based automation, see Echoo vs Grammarly (opens in new tab) and the Grammarly alternative for Mac (opens in new tab).
