Marketing Email

Marketing Email Creator

Create compelling marketing emails in your authentic brand voice.

Before Writing

1. Identify the email type:

• Newsletter (regular value delivery)
• Launch announcement (course/product promotion)
• Nurture sequence (relationship building)

1. Run the rhetoric selector:

``bash python shared/rhetoric_selector.py --type email_newsletter # or --type email_launch # or --type email_nurture ``

1. Review context:

• [VOICEGUIDE.md](../../config/VOICEGUIDE.md)
• [BUSINESSCONTEXT.md](../../config/BUSINESSCONTEXT.md)
• [CONTENTPILLARS.md](../../config/CONTENTPILLARS.md)

Email Anatomy

Subject Line

• 4-7 words ideal
• Create curiosity or promise value
• Rhetorical devices work brilliantly here (antithesis, tricolon)
• Avoid spam triggers (FREE, URGENT, !!!)
• Test with: "Would I open this?"

Subject line formulas:

• Curiosity: "The thing nobody tells you about [X]"
• Benefit: "How to [achieve X] in [timeframe]"
• Story: "I almost [dramatic thing] until..."
• Direct: "[Specific thing] that changed my [result]"
• Antithesis: "[Old way] vs [new way]"

Preview Text

• First 40-90 characters visible in inbox
• Complements (doesn't repeat) subject line
• Often the first sentence of your email

Opening

• Don't waste the first line on "Hi [Name]"
• Start with something interesting
• Hook them immediately - they're deciding whether to keep reading

Body

• Short paragraphs (2-3 sentences max)
• One idea per paragraph
• Use rhetorical devices for flow and emphasis
• Personal stories are your secret weapon
• Specifics > generalities (numbers, examples, real situations)

CTA (Call to Action)

• ONE clear CTA per email
• Button or link, not both
• Action-oriented text ("Join the masterclass" not "Click here")
• Earned, not forced - comes after providing value

Sign-off

• Keep it simple: Your name or "- [Name]"
• P.S. lines work for secondary CTAs or personal notes

Templates

See templates folder:

• [Newsletter](templates/newsletter.md)
• [Launch Announcement](templates/launch-announcement.md)
• [Nurture Sequence](templates/nurture-sequence.md)

Voice Reminders

From your [VOICEGUIDE.md](../../config/VOICEGUIDE.md):

Do

• Write like you're emailing one person
• Share real stories and real numbers
• Be genuinely helpful before asking for anything
• Use "you" more than "I"
• Maintain your spelling conventions

Don't

• Start with "I hope this email finds you well"
• Use "we" when you mean "I"
• Include multiple CTAs competing for attention
• Write walls of text without line breaks
• Sound like a marketing department

Email Types Explained

Newsletter

Purpose: Regular value delivery, staying top of mind Frequency: Weekly or bi-weekly Mix: Technical tip + industry observation + personal note CTA: Soft (reply, share, optional product mention)

Launch Announcement

Purpose: Promote a specific offering Frequency: During launch windows only Structure: Problem > Solution > Proof > Offer > Urgency CTA: Direct (join, enrol, sign up)

Nurture Sequence

Purpose: Build relationship over time with new subscribers Length: 5-7 emails over 2-3 weeks Arc: Welcome > Value > Story > More value > Soft pitch CTA: Graduated (reply > free resource > learn more > offering)
