Module 1, Client Communication & Email Drafting
⚡ The 30-second version. Use it for: drafting client emails, IRS/state-notice replies, tone fixes, and inbox triage. The method: brief the AI in a sentence and edit the draft in seconds, you stay the author. Start here: the 15-minute starter at the bottom.
This is the easiest place to get a fast, visible win with AI. People use it for: drafting client emails, replying to IRS/state notices, refining tone, client letters, sales/intake scripts, and triaging a full inbox.
"Most staff use it for drafting client emails and tax research." "Drafting emails, evaluating client situations." "Refining emails or memos."
If your firm only adopts AI for one thing this quarter, make it this. The work is high-volume, low-stakes-per-item, and the quality bar is "clear and professional," which AI hits reliably.
▶ See it in action: a before/after worked example, a 15-second brief turning into a finished, on-brand client email.
What "good" looks like
The goal is not "AI writes my emails for me." It's "I describe the situation in 15 seconds of plain talk, and AI gives me a clean draft I edit in 30 seconds." You stay the author and the reviewer; AI removes the blank-page tax.
Three jobs AI does well here:
- Draft, turn bullet points or a forwarded thread into a polished reply.
- Reframe tone, make a blunt draft warmer, a rambling one tighter, a tense one calmer.
- Triage, summarize a long thread and tell you what actually needs a response.
The approach: a reusable "house style" + a fast draft loop
Step 1, Set your house style once (do this today, reuse forever)
The biggest quality jump comes from telling AI how your firm sounds. Write this once and paste it at the top of any drafting session (or save it as a Claude Project / Custom Instruction so you never retype it):
You are helping me draft client emails for my CPA firm. Our house style:
- Warm but professional. Plain English, not jargon. We explain the "why," briefly.
- Short paragraphs. Lead with the answer or the ask, then the detail.
- We never give a definitive answer on something uncertain, we say what we know,
what we need, and the next step.
- Sign-offs are simple ("Best," / "Thanks,"). No exclamation-point overload.
- Never invent facts, figures, deadlines, or citations. If you need a fact I didn't
give you, leave a clearly marked [BRACKET] for me to fill in.
Always give me the draft only, ready to edit, no preamble.
That last line matters: it stops the assistant from burying your draft under "Here's a draft you might consider..."
Step 2, The fast draft loop
Talk to it like you'd brief an assistant. You do not need full sentences.
Client emailed asking why their Q3 estimate went up vs last year. Reason: higher
1099 income + they stopped the SEP contribution. Reassure them, explain in plain
terms, offer a 15-min call. Keep it short.
You'll get a clean draft. Then iterate in one line: "Warmer." / "Cut it 30%." / "Add a sentence on how to avoid a penalty."
Copy-paste prompt library
1. Reply to a forwarded client thread
Here's a thread from a client. Draft my reply: [paste/anonymize]. I want to
[your goal in plain words]. Match my house style above.
2. Respond to an IRS / state notice (client-facing explanation)
A client got this notice: [summarize the notice, type, tax year, amount, what
it claims]. Draft an email that (a) tells them not to panic, (b) explains in plain
English what it means, (c) lists what I need from them, (d) says we'll handle the
response. Do not state any tax position as settled, frame it as what we'll review.
3. The "make this not sound annoyed" pass
Here's my draft. The client is the third late one this week and it shows. Keep my
points but make the tone neutral-professional, not irritated: [paste draft]
4. Inbox triage
Here are subject lines / snippets from my inbox: [paste]. Group them into:
(1) needs a real reply from me today, (2) quick acknowledgment, (3) can wait /
delegate. For group 1, give me a one-line draft reply each.
5. Intake / sales reply to a prospect
A prospect asked: [paste]. We offer [services]. Draft a reply that answers their
question, shows we're a fit, and proposes a discovery call. Don't quote a price, say pricing follows a quick scoping conversation.
6. Translate "accountant" into "human"
Rewrite this so a non-accountant business owner immediately understands it, without
losing accuracy: [paste the technical version]
Tool picks
-
Claude (default for the Lab), best tone control and longest, most reliable drafts. Use Projects to store your house style + firm context so every chat starts pre-loaded.
-
Microsoft Copilot / Gemini in Gmail, if you live in Outlook/Gmail, the in-app draft button is the lowest-friction entry point. Tone control is weaker; good for first drafts.
-
A dedicated "Email" Custom Instruction or saved prompt beats a fancier tool you have to leave your inbox to use. Friction kills adoption.
Guardrails (read this before you send anything)
-
Confidentiality first. Don't paste SSNs, EINs, account numbers, or full financial detail into a consumer chat tool. Anonymize: "the client," "$X," "[STATE]." Use a business/enterprise plan with a no-training data agreement if you want to paste real client context routinely. Note IRC §7216 can require client consent before taxpayer information goes to a third-party service. (See Guardrails for the full rules.)
-
You are the author of record. A CPA's communication carries professional weight. Read every word before it goes out. AI drafts; you decide and sign.
-
Never let it assert a tax position, deadline, or number you didn't give it. The bracket trick (tell it to leave
[BRACKETS]) prevents confident-sounding fabrication. -
Watch for over-promising. AI tends toward reassuring, agreeable language. For notices, audits, or anything contested, downgrade certainty by hand.
Your 15-minute starter
- Paste the house-style block above into a new Claude chat (or save it as a Project).
-
Grab the last real client email you wrote from scratch. Brief AI in one or two plain-English lines the way you would a junior staffer.
-
Compare its draft to what you actually sent. Note where it nailed it and where it missed your voice, then add one line to your house style to fix the miss.
-
Do this 3 times. By the third, the drafts will need almost no editing, and you'll have a house-style block worth saving for the whole firm.
Win condition: next time a client email comes in, your instinct is "brief it" instead of "stare at the blank reply box."
