Great email copywriting is the difference between emails that convert and emails that get deleted. This comprehensive guide covers the principles, techniques, and frameworks for writing emails that engage readers and drive the actions you want.
The Fundamentals of Email Copywriting
Core principles that apply to all email writing.
Understanding Your Reader
They're Busy: Your reader has limited time and attention. Respect it.
They're Skeptical: They've seen countless marketing emails. Earn their trust.
They're Asking "What's In It For Me?": Every sentence should answer this question.
They're Distracted: Emails are read on phones, between meetings, while multitasking.
The Job of Email Copy
Get Opened: Subject line and preheader must compel the open.
Get Read: First lines must hook them to continue.
Get Clicked: Body must build to an irresistible action.
Build Relationship: Even selling emails should strengthen the connection.
Writing Mindset
Write to One Person: Use "you" and "your." Write like you're talking to a friend.
Be Specific: Vague claims are forgettable. Specific details are memorable.
Be Clear, Then Clever: Clarity always wins. Cleverness is optional.
Edit Ruthlessly: Cut everything that doesn't serve the goal.
Subject Lines That Get Opens
The most important 50 characters you'll write. For comprehensive strategies, see our email subject lines guide.
Subject Line Principles
Be Specific: "Your order shipped" beats "Order update"
Create Curiosity: Open a loop the reader wants to close
Promise Value: Make clear what they'll get by opening
Be Honest: Never mislead—it destroys trust
Keep It Short: 40-50 characters is ideal. Mobile cuts off longer lines.
Subject Line Formulas
The Direct Promise: "How to [achieve desired result]"
- "How to double your open rates in 30 days"
- "How to write emails people actually read"
The Question: "Are you making this [mistake]?"
- "Are you making this email mistake?"
- "Is your email list costing you money?"
The List: "[Number] ways to [achieve result]"
- "7 ways to write better subject lines"
- "5 email mistakes that hurt deliverability"
The Curiosity Gap: "The [thing] most [people] overlook"
- "The metric most email marketers ignore"
- "The word that kills email conversions"
The Personal Touch: "[Name], [personal reference]"
- "Sarah, your cart is waiting"
- "Quick question for you, Mike"
The Urgency (use sparingly): "[Time frame]: [opportunity/action]"
- "Ends tonight: 40% off everything"
- "Last chance to save your seat"
Subject Line Best Practices
Do:
- Test constantly
- Match subject to content
- Use sender name strategically
- Consider emoji carefully
- Write multiple options
Don't:
- Use ALL CAPS
- Overuse punctuation!!!
- Say "Newsletter" or "Update"
- Be misleading
- Use spam trigger words
Preheader Text
What It Is: The preview text that appears after the subject line.
How to Use It:
- Extend the subject line
- Add context or tease content
- Complement, don't repeat
Examples:
Subject: Your order has shipped Preheader: Track your package and see delivery updates Subject: The mistake that killed our campaign Preheader: (And how we fixed it in 24 hours) Subject: Quick question for you Preheader: Reply takes 10 seconds
Opening Lines That Hook
The first line determines whether they keep reading.
Opening Strategies
The Personal Connection:
Hey [Name], I noticed you downloaded our email marketing guide last week. How's the implementation going?
The Pattern Interrupt:
Let me tell you about the worst email I ever sent. It had a 2% open rate. Here's what I learned...
The Direct Value:
I'm going to share the exact subject line formula that consistently gets us 40%+ open rates. No fluff—just the framework and examples.
The Empathy Hook:
Writing emails that actually get read is hard. I know because I used to send emails into the void for months before figuring out what works.
The Timely Hook:
With the holiday season approaching, your email strategy is about to be tested. Here's how to stand out in crowded inboxes.
What to Avoid
Don't Start With:
- "I hope this email finds you well"
- "Just checking in"
- "As you know"
- Company news nobody asked for
- The word "I" (start with "you" instead)
Body Copy That Engages
Keeping readers hooked through the entire email.
Structure for Readability
Short Paragraphs: 2-3 sentences maximum. One sentence is fine.
White Space: Let the email breathe. Dense text is hard to read.
Scannable Format: Use bullets, subheadings, bold text for key points.
Single Column: Especially for mobile. Simple is better.
Writing Techniques
The AIDA Framework:
- Attention: Hook them with the opening
- Interest: Build curiosity and engagement
- Desire: Make them want what you're offering
- Action: Tell them exactly what to do
The PAS Framework:
- Problem: Identify their pain point
- Agitation: Make them feel that pain
- Solution: Present your solution
The 4 Ps Framework:
- Promise: What they'll get
- Picture: Help them visualize the benefit
- Proof: Why they should believe you
- Push: Call to action
Example: PAS in Action
Subject: Why your emails aren't getting opened Hey [Name], You spend hours crafting the perfect email. You hit send with confidence. Then... crickets. Low open rates. Minimal clicks. No conversions. It's frustrating. You know your content is valuable. But if nobody opens the email, nobody sees it. The problem isn't your content. It's your subject lines.

Common Copywriting Mistakes

Problem: Important information hidden in paragraph three. Fix: Put the most important thing first.
Mistake 3: Weak CTAs
Problem: "Click here" or unclear next steps. Fix: Specific, action-oriented CTA text.
Mistake 4: Wall of Text
Problem: Dense, unbroken paragraphs. Fix: Short paragraphs, white space, scannable format.
Mistake 5: Being Clever Over Clear
Problem: Jokes or wordplay that obscure the message. Fix: Clarity first, cleverness second.
Mistake 6: Generic Messages
Problem: Could be from any company to any person. Fix: Specific details, personalization, unique voice.
