Email is the universal business skill. Everyone writes it, most people are bad at it, and Claude can make you dramatically better at it overnight.
The Email Prompting Framework
Every email prompt should include four things:
- Context — Who are you writing to and why?
- Goal — What action do you want the reader to take?
- Tone — How should this sound?
- Constraints — Length, format, things to avoid
Write a cold outreach email to [recipient name], [their title] at [company]. Context: [why you're reaching out]. Goal: [what you want them to do — e.g., book a 15-min call]. Tone: professional but conversational, like a knowledgeable peer, not a salesperson. Constraints: under 125 words, short paragraphs (2-3 sentences max), no buzzwords, no fake personalization. Include a subject line.

What's the most important element when asking Claude to draft an email?
Five Email Templates That Work
1. The Follow-Up That Doesn't Feel Desperate
Write a follow-up email to someone who hasn't responded to my initial outreach 5 days ago. Original email topic: [topic]. Keep it under 50 words. Don't be apologetic. Don't say 'just checking in' or 'bumping this.' Add one new piece of value or insight that makes responding feel worthwhile.
2. The Difficult Internal Email
Write an internal email to [audience] about [the situation]. I need to be direct and transparent without creating panic. Include: what happened, what we're doing about it, what changes (if any), and next steps. Tone: calm, confident, and honest. Under 200 words.
3. The Customer Save
Write a response to a customer who wants to cancel their subscription. Their reason: [reason]. We want to save them if possible, but not be pushy. Acknowledge their concern genuinely, offer one specific solution, and make it easy to cancel if they still want to. Tone: empathetic, not desperate.
4. The Warm Introduction Request
Write an email asking [person] to introduce me to [target person] at [target company]. Context: [why I want the introduction]. Make it easy for them to forward — include a short blurb about me they can paste. Keep it respectful of their relationship and under 100 words.
5. The Batch Triage
Here are [X] emails I need to respond to. For each one:\n1. Priority: urgent / important / low / archive\n2. Suggested action: reply / delegate / defer / archive\n3. If 'reply': draft a concise response\n\nGroup by priority in your output. My default tone: professional, direct, warm.\n\n[Paste emails below]
Pro Tip
For batch email triage, set up a Project with your communication style and common contacts. Claude will write replies that actually sound like you.
The Voice Matching Trick
If you want emails that sound like YOU, not like an AI:
- Paste 5-10 emails you've written that represent your best writing
- Ask Claude: "Analyze my writing style — tone, sentence length, vocabulary, patterns"
- Save Claude's analysis in your Project instructions
- Now every email Claude drafts will match your voice
Scenario
Your biggest client just emailed to say they're considering switching to a competitor. The email is polite but firm. You need to respond within the hour.
Advanced: Email Sequences
When a single email won't do the job, use Claude to map out the full sequence.
Design a [X]-email sequence for [goal]. Audience: [who]. Spacing: [how many days between emails]. For each email, give me:\n- Subject line\n- Core message (one sentence)\n- Full draft (under 100 words each)\n- CTA\n\nRules: Each email should stand alone. Don't reference previous emails explicitly. Escalate value, not urgency. No guilt trips.
Common Mistakes to Avoid
Over-prompting tone. Saying "professional but casual but warm but authoritative" gives Claude mixed signals. Pick one primary tone and one modifier. "Direct and warm" is enough.
Skipping context. "Write a follow-up email" gives you generic slop. "Write a follow-up to my CTO prospect who asked about our security compliance and then went quiet" gives you something useful.
Ignoring the subject line. The subject line is half the battle. Always ask for it explicitly, or ask Claude to generate 5 options and pick the best one.
