**Source**: Compiled from Copyhackers, Really Good Emails, Val Geisler, Joanna Wiebe, and direct response email best practices.
**Core Principle**: Email is a conversation, not a broadcast. Every email should feel like it came from a person, provide value, and respect the inbox.
**Why This Matters**: Email still delivers the highest ROI of any channel ($36 for every $1 spent). But only if it gets opened, read, and clicked.

Write 10 subject lines for: Email type: [welcome, newsletter, sales, etc.] Content/offer: [what the email is about] Audience: [who receives it]
Write a [type] email for: Product/service: [description] Goal: [click, reply, buy, etc.] Recipient context: [new subscriber, past customer, etc.]
Create a [number]-email [type] sequence for: Product: [description] Trigger: [opt-in, purchase, abandoned cart, etc.] End goal: [purchase, demo, engagement, etc.]
Review this email and suggest improvements: [paste email] Current open rate: [%] Current click rate: [%]

## Subject Line Formulas That Work ### Category 1: Curiosity Create a gap between what they know and want to know **Formulas:** - "[Unexpected thing] about [topic]" - "I was wrong about [topic]" - "This changes everything" - "Quick question" - "Weird thing happened..." **Examples:** - "I was wrong about cold email" - "This surprised me about [product]" - "The $100K email (not clickbait)" --- ### Category 2: Benefit/Value Promise clear value for opening **Formulas:** - "[Number] ways to [achieve outcome]" - "How to [achieve result]" - "The [adjective] way to [do thing]" - "[Resource] inside" **Examples:** - "7 ways to fix your landing page" - "Your [Month] marketing calendar is ready" - "The lazy way to write better emails" --- ### Category 3: Personal/Conversational Feels like it came from a person **Formulas:** - "Quick question about [topic]" - "Thoughts on [topic]?" - "This made me think of you" - "Re: [previous topic]" (use sparingly) **Examples:** - "Quick question about your goals" - "Thoughts on this approach?" - "Made me think of you" --- ### Category 4: Urgency/Scarcity Time-sensitive (only if genuine) **Formulas:** - "[X] hours left" - "Last chance: [offer]" - "Closing [timeframe]" - "Before you miss this" **Examples:** - "24 hours left (then price goes up)" - "Closing at midnight" - "Last call for [offer]" --- ### Category 5: List/Story Promise organized content **Formulas:** - "[Number] [things] you need to [outcome]" - "A story about [topic]" - "How I [achieved result]" **Examples:** - "3 emails that made us $50K" - "A story about my worst launch" - "How we fixed our churn problem" --- ## Subject Line Power Words **Open-Boosters:** - Quick, Fast, Easy - New, Now, Today - How, Why, What - You, Your - Free, Save - [Numbers] **Spam-Triggers to Avoid:** - FREE!!!

## The Anatomy of a High-Performing Email ### Opening Line (The Hook) - First 1-2 sentences determine if they read on - NO "Hope this finds you well" - Start with curiosity, story, or direct value **Good Opens:** - "I made a mistake last week." - "Quick question for you:" - "You asked for this, so here it is." - "[Name], I noticed something about your [X]..." - Direct statement of value **Bad Opens:** - "Hope this email finds you well!" - "Just checking in..." - "I wanted to reach out because..." - "As per my last email..." --- ### Body (The Value) - One idea per email (focused) - Short paragraphs (1-3 sentences max) - White space is your friend - Write for mobile (52% open on mobile) - Use bold for emphasis sparingly - Bullets for lists **Reading Length Guidelines:** - Newsletter: 200-400 words - Sales email: 150-300 words - Welcome email: 150-250 words - Promotional: 100-200 words --- ### CTA (The Action) - One primary CTA per email - Make it button or obvious link - Tell them exactly what happens when they click - CTA above and below lo
