Structure Framework

Every email follows this structure:

Subject: [Specific, not generic — include key value or action]

[Opening — context in one sentence: why you are writing]

[Body — 2-3 short paragraphs max, bullet points for multiple items]

[CTA — one clear, specific ask]

[Sign-off — matched to relationship level]

Tone Calibration

Tone	Characteristics	When to Use
Formal	Complete sentences, no contractions, titles, "Dear..."	C-suite, legal, first contact with enterprise
Professional	Direct but warm, contractions OK, first names	Clients, colleagues, vendors
Casual	Conversational, personality OK, still clear	Internal team, close working relationships
Urgent	ACTION REQUIRED flag, bold deadlines, consequences	Time-sensitive, blocking issues

Subject Line Formulas

Formula	Example
Action + Topic + Deadline	"Review: Q1 Campaign Brief by Friday"
Number + Benefit	"3 Quick Wins from Your GA4 Data"
Question	"Can we schedule 15 min to discuss the Shopify migration?"
Value + Context	"Your Klaviyo Audit Results (3 Revenue Opportunities)"
Urgency + Specificity	"Action needed: Tracking code missing from 4 pages"

Key Principles

One email, one CTA. Do not dilute with multiple asks.
150 words max for most emails. Respect the reader's time.
Specific subject lines. "Q4 Campaign Brief — Review by Friday" not "Update."
Add value, not volume. Never "just checking in" without new information.
Active voice for CTAs. "Can you review this by Thursday?" not "It would be great if this could be reviewed."
Context first. Recipient should know why they are reading within the first sentence.

Anti-Patterns

"Just checking in" without adding value
Walls of text (>200 words for a simple ask)
Passive voice CTAs ("It would be great if...")
Multiple asks in one email
Generic subject lines ("Update", "Quick question", "FYI")
Marking everything as urgent
Reply-all when only one person needs to respond
Sending when emotional — draft, wait, re-read

For templates and follow-up cadence, see REFERENCE.md.

Brand Context (Optional)

If brand-profile.json exists in the working directory, read it before composing emails. Use the formal_casual axis to set salutation and sign-off style, voice descriptors to guide subject line personality, and colors for email template accent recommendations. This profile is produced by the brand-dna skill.
