Email Copy And Subject Lines

Email Copy and Subject Lines

Overview

This skill covers best practices for writing B2B marketing emails that get opened, read, and acted on—including subject line construction, preview text, body copy structure, CTA language, outbound cold email, and common copy mistakes to avoid. All practices are sourced exclusively from Exit Five podcast guests; nothing has been added from general marketing knowledge. Where guests disagree, those disagreements are surfaced explicitly rather than resolved.

The Email Chain: Optimizing Every Element in Sequence

Treat email engagement as a chain where each element must pull the reader forward to the next. A break anywhere in the chain loses the reader. Optimize in this sequence: (1) from name/alias, (2) subject line, (3) preview text, (4) email headline, (5) body content. (Source: Jay Schwedelson, Episode #329)

From name:

• Send emails from a person's name (e.g., "Jen from Gong" or "Dave from Exit Five") rather than just the company name to create a direct, personal connection. (Source: Jay Schwedelson, Episode #167)
• Alternatively, treat the friendly from name as an extension of the subject line and change it per send to reflect the email's content or offer (e.g., "Acme Events," "Acme Demo," "Acme Special Guide"). This approach is reported to increase open rates by approximately 31% and reduce recipient fatigue. (Source: Jay Schwedelson, Episodes #167 and #329)
• (Note: these two from-name approaches are contested — see Where Experts Disagree)

Preview text:

• Start email preview text with continuation words—"and," "but," or "plus"—to create a psychological chain that pulls readers from the subject line into the email. This tactic significantly lifts open rates. (Source: Jay Schwedelson, Episode #329)

Subject Line Construction

Length and Format

• Keep outbound email subject lines to 3–4 words maximum. Write in lowercase, avoid formal language, and make them specific to the recipient or their company. Example: "quarterly earnings [company name]" rather than "URGENT: Quarterly Earnings Discussion." (Source: Alex Fine, Episode #256)
• Write subject lines in sentence case (capitalize only the first word and proper nouns). Title case and all-caps read as corporate jargon and reduce open rates. (Source: Samar Owais, Episode #247)
• Include a colon after the first word or phrase to create a natural pause and structure. Example: "Invited: AI is going to take your job." (Source: Jay Schwedelson, Episode #167)

Personalization

• Include the recipient's company name in the subject line to increase open rates by approximately 41%. Example: "Is Acme at risk?" (Source: Jay Schwedelson, Episode #167)
• Include the recipient's job function in the subject line to increase open rates by approximately 38%. Example: "just for B2B marketers" or "just for HR Pros." (Source: Jay Schwedelson, Episode #167)
• Include the recipient's industry vertical in the subject line to signal relevance. Example: "This is trending in the retail sector." (Source: Jay Schwedelson, Episode #167)
• Segment subject lines by customer longevity. Use different subject lines for new versus long-term customers. Example: "This is just for our new customers" or "This is for customers that have been with us for five years." (Source: Jay Schwedelson, Episode #167)

Words and Phrases to Avoid

• Do not use the word "webinar" in subject lines—it depresses open rates. Focus on the topic or benefit instead. Example: "How to implement a change management office" rather than "New webinar: How to implement a change management office." The same applies to "ebook" and other generic delivery-vehicle terms. (Source: Jay Schwedelson, Episode #167)
• Do not include edition numbers (e.g., "June Edition," "Issue #27") in newsletter subject lines. These become outdated and convey no value. Focus on the actual topic, key stat, or benefit. (Source: Jay Schwedelson, Episode #167)
• Do not use fake "Re:" or "Fwd:" formatting to trick recipients into opening. This triggers spam complaints, violates anti-spam regulations, and damages brand reputation. (Source: Jaina Mistry, Episode #241)

Alignment and Accuracy

• Ensure the subject line accurately reflects what's in the email and aligns with the recipient's stage in the buyer journey. If the subject line promises one thing and the email delivers another, open rates will suffer. Test subject lines against actual email content and the recipient's prior actions. (Source: Samar Owais, Episode #247)
• Do not use clickbait subject lines that don't match email content. The only difference between a great hook and clickbait is delivering on the promise in the email body. (Source: Jaina Mistry, Episode #241)

Competitive and Curiosity Tactics

• Use competitive positioning in subject lines by referencing your company versus a competitor. Example: "Acme vs. Competitor X." This creates intrigue and signals a comparison recipients want to see. (Source: Jay Schwedelson, Episode #167)
• Rotate 3–4 subject line variations per campaign send. Each variation should convey the same core message but be formatted and personalized differently to bypass spam filters and avoid triggering repetitive-pattern detection. (Source: Alex Fine, Episode #256)

Body Copy Structure and Tone

Write to One Person, One Message, One CTA

Apply three unbreakable rules to every email: (1) Write to one specific person or persona, not a broad audience; (2) Have one core message or theme; (3) Have one type of call-to-action—all links lead to the same destination. These constraints force clarity and prevent cognitive overload. (Source: Samar Owais, Episode #247)

Conversational Tone and Framing

• Treat the inbox as an invited personal space. Write conversationally, avoid corporate jargon, and treat the recipient as a real person rather than a list entry. (Source: Alyssa, Episode #312)
• Treat every email as a one-to-one conversation, not a broadcast. Write as if you're talking to one person who has a specific context, pain point, and need. Recipients can sense whether you're talking to them or at them. (Source: Samar Owais, Episode #247)
• Write marketing emails as if writing to a friend. Open a blank email, put in a friend's or customer's name, and write as you would to them one-on-one. This naturally produces more human, personalized copy. (Source: Pierce Uijainwalla, Episode #167)
• Structure outbound emails to resemble internal conversations between colleagues rather than formal marketing messages. Use casual language, short sentences, and a conversational tone. Spam filters are trained to detect formal, templated marketing language. (Source: Alex Fine, Episode #256)

Pronoun Discipline

• Replace "we/I/our" language with "you/your" throughout email copy. Replace phrases like "We are excited to announce" with "You can now do this" or "Your [role/goal] will benefit from this." This pronoun shift dramatically improves engagement because recipients care about their own problems, not your announcements. (Source: Sheri Otto, Episode #247)

Length and Visual Structure

• Limit any single block of text to four lines maximum. Longer blocks appear overwhelming and discourage reading, especially on mobile where two-line desktop text can become five lines. Break up content with bullet points, different colors, and visual blocks. (Source: Jay Schwedelson, Episode #241)
• For prospects new to your brand, keep emails under 75 words. New prospects barely opened the email and won't read long blocks of text. For existing customers or highly engaged subscribers, you can be more verbose. (Source: Jay Schwedelson, Episode #241) (Note: this brevity rule is contested for cold outbound — see Where Experts Disagree)
• For longer, content-heavy emails (e.g., repurposed webinar or report content), add a brief "What You'll Learn" section at the top so readers can decide whether to engage and have a roadmap for reading. Mention at the end that a full recording or deeper resource is available. (Source: Samar Owais, Episode #247)

Hooks and Context

• Lead email copy with a hook that creates curiosity or addresses a pain point. Example: "Tired of the same old [problem]?" or "Here's what's changing in [industry]." The hook should make recipients want to continue reading. (Source: Pierce Uijainwalla, Episode #167)
• Ensure email copy clearly explains what the email is about and why the recipient should care. Avoid making recipients work to understand the message. High cognitive load causes recipients to ignore or delete the email. (Source: Pierce Uijainwalla, Episode #167)

Bullet Points

• When using bullet points, add a "so you can" or "so that" clause to each bullet to connect the feature to the recipient's actual goal. Example: instead of "Enhanced patient member safety and quality," write "Enhanced patient member safety and quality so you can reduce liability and improve outcomes." (Source: Sheri Otto, Episode #247)

Subheads

• Write email subheads from the reader's perspective, answering "why should I care?" rather than just describing what something is. Example: instead of "Building a high ARR per employee business," write "How to build a high ARR per employee business." (Source: Samar Owais, Episode #247)

Language Specificity

• Replace generic industry buzzwords ("advanced workflow," "emerging technologies," "best-in-class solutions") with specific language that speaks to the unique pain points, terminology, and goals of your target industry. Generic phrases signal lazy writing or AI-generated copy. (Source: Sheri Otto, Episode #247)

Follow-Up and Nurture Emails

• When sending a follow-up email after a significant action (e.g., whitepaper download), reference that action in the email body. Don't assume recipients remember what they downloaded weeks ago. Lead with the problem they were trying to solve, then connect your follow-up content to that problem. (Source: Sofia Silva, Episode #247)

Call-to-Action (CTA) Copy

• Write CTA buttons in first person rather than imperative form. Example: "I want to see the secrets" or "Show me the full trends report" instead of "Read the case study" or "Register now." First-person CTAs increase click-through rates by over 20%. CTAs can be full sentences, not just 2–3 words. (Source: Jay Schwedelson, Episode #167)
• Do not use "Register Now" as a CTA button for webinar or event emails. Use first-person, benefit-driven alternatives like "I want in," "Save my spot," or "I can't wait." (Source: Jay Schwedelson, Episode #167)
• Reframe CTA copy from action-focused ("Download the infographic") to benefit-focused ("Get the infographic" or "See how to [solve problem]"). Make the action feel valuable, not transactional. (Source: Samar Owais, Episode #247)

Outbound Cold Email

Prospect-Centric Messaging

• Audit outbound emails for "we," "our," and company-name language. Most cold outbound is dominated by self-referential messaging. Instead, structure outbound to focus on the prospect's problem, how they currently solve it, and the unintended consequences of their current approach. Do not mention your product, company, or solution in the initial outbound message. The goal is to get the prospect thinking about their own behavior and situation before introducing your offering. (Source: Jen Allen-Knuth, Episodes #308 and #343)

The Perception Curiosity Structure

Write cold emails that trigger perception curiosity—the itch to scratch when someone hears something that contradicts what they believe to be true. Use this five-step structure:

1. Subject line that prompts opening based on the prospect's context, not your product (e.g., "Uber bill" rather than a product pitch)
2. Establish context with a relevant statistic about the prospect's situation (e.g., "Chicago gets 119 rainy days a year")
3. Highlight a behavior gap or unintended consequence (e.g., "only 5% remember to bring an umbrella, so 95% order Ubers at surge pricing")
4. Reference someone else who solved it differently (e.g., "Betty found a way to cut her Uber bill by $200/month")
5. Ask if they're open to learning how—without mentioning your product

This approach makes prospects think about their own behavior before asking them to think about you. (Source: Jen Allen-Knuth, Episode #343)

(Note: the length this structure requires is contested — see Where Experts Disagree)

Event and VIP Invite Copy

• For VIP dinner invitations, keep copy short and emphasize scarcity and peer attendance. Reference previous attendees from recognizable companies. Use language like "We have a few slots left. Can I save one for you?" to create urgency. This leverages both FOMO and social proof to increase acceptance rates. (Source: Natalie Taylor, Episode #162)

AI in Email Copywriting

Do not use AI as your primary email copywriter. AI tends to produce generic, median-quality output that lacks the specificity, personality, and human insight needed to stand out—especially in nurture emails where connection and relevance are critical. Use AI for ideation and editing, but have a human write the core copy. AI can be trained to match your voice and brand, which may allow a more integrated role with proper setup and oversight. (Note: the appropriate role of AI in copy workflows is contested — see Where Experts Disagree) (Source: Sofia Silva, Episode #247)

Where Experts Disagree

1. Should you send emails from a person's name or vary the from name by content type?

Support summary: 2 positions, both attributed to the same guest (Jay Schwedelson), with his later episode favoring the content-type approach

Position A — Send from a person's name: Jay Schwedelson (Episode #167) recommended using a person's name in the friendly from field (e.g., "Dave from Exit Five") as a best practice for creating personal connection and improving performance. The email address doesn't change; only the display name includes the person's name. The email body must also feel one-to-one to maintain this connection.

Position B — Vary the from name by content type: Jay Schwedelson (Episodes #167 and #329) also recommended treating the friendly from name as an extension of the subject line and changing it per send to reflect the email's content or offer (e.g., "Acme Events," "Acme Demo," "Acme Special Guide"). He cited a ~31% open rate lift and reduced recipient fatigue because recipients perceive different senders. In his later appearance (Episode #329, February 2026), he reiterated this content-specific approach without mentioning personal names.

Context dependency: These two tactics could theoretically be combined (e.g., "Jen from Acme Events"), but as stated they represent distinct and conflicting recommendations about what the from name should prioritize—personal identity vs. content-type signaling.

Trend note: Schwedelson's later episode (329, February 2026) emphasizes content-specific from names without mentioning personal names, suggesting a possible shift in his own thinking toward the content-type approach.

What this means for you: The from name is the first thing recipients see and directly affects open rates. Decide whether you're optimizing for personal connection or content relevance—or test a hybrid approach that combines both signals.

2. How long should emails to new prospects be?

Support summary: 3 vs 1

Position A — Under 75 words (1 supporter): Jay Schwedelson (Episode #241) explicitly stated that for prospects new to your brand, keep emails under 75 words. His reasoning: new prospects barely opened the email and won't read long blocks of text, so brevity is essential.

Position B — Structure and prospect-centricity matter more than a word-count ceiling (3 supporters):

• Jen Allen-Knuth (Episode #343) described a five-step "perception curiosity" cold email structure that inherently requires more than 75 words to execute properly. No word-count constraint was mentioned—the emphasis is on the structural elements that trigger curiosity.
• Jen Allen-Knuth (Episode #308) advocated for prospect-centric outbound messaging focused on context, behavior, and unintended consequences—a framework that prioritizes structure and relevance over strict brevity.
• Alex Fine (Episode #256) recommended writing outbound emails to look like internal company conversations using casual language and short sentences, without specifying a word count limit.

Context dependency: Schwedelson's under-75-word rule is explicitly for brand-new prospects. Allen-Knuth's framework is also aimed at cold outbound. Both are addressing the same scenario, making this a genuine disagreement on approach rather than a context mismatch.

Trend note: Allen-Knuth's most recent appearance (Episode #343, April 2026) reaffirms the structured multi-step approach, suggesting no convergence toward Schwedelson's brevity rule over time.

What this means for you: Choosing the wrong length strategy for cold prospects directly affects reply rates. A marketer following Schwedelson's rule would cut Allen-Knuth's five-step structure in half, potentially eliminating the curiosity mechanism that drives responses. Consider testing both approaches against your specific audience and offer type.

3. Should AI be used as a primary email copywriter?

Support summary: 1 vs 1 (both positions drawn from the same guest)

Position A — AI as assistant only: Sofia Silva (Episode #247) explicitly warned against using AI as the primary copywriter, citing its tendency toward generic output that lacks the human insight needed to stand out, especially in nurture emails.

Position B — AI integrated into the copy workflow with proper training: Sofia Silva (Episode #247) also noted that AI can be trained to match your voice and brand—implying a more integrated role is acceptable with proper setup and human oversight.

What this means for you: Silva's own framing contains both caution and conditional acceptance. The practical takeaway is that the risk lies in using AI without training or oversight, not in using it at all. Define what "primary copywriter" means for your workflow and ensure human review is built in regardless.

What NOT To Do

• Don't lead outbound emails with your company, product, or solution. The "we problem" is endemic in cold outbound. Emails that open with the sender's company, features, and why they're better fail to break through. (Source: Jen Allen-Knuth, Episodes #308 and #343)
• Don't use fake "Re:" or "Fwd:" subject line formatting. This tricks recipients, triggers spam complaints, violates anti-spam regulations, and can result in fines. (Source: Jaina Mistry, Episode #241)
• Don't use clickbait subject lines that don't match email content. Examples: "Your credit card failed" when it's actually a renewal notice. The only difference between a great hook and clickbait is delivering on the promise. (Source: Jaina Mistry, Episode #241)
• Don't use "webinar," "ebook," or other delivery-vehicle terms in subject lines. Recipients care about the topic, not the format. (Source: Jay Schwedelson, Episode #167)
• Don't use "Register Now" as a CTA. It's generic and uninspiring. Use first-person, benefit-driven alternatives. (Source: Jay Schwedelson, Episode #167)
• Don't use title case or all-caps in subject lines. Sentence case performs better and reads as more conversational. (Source: Samar Owais, Episode #247)
• Don't include edition numbers in newsletter subject lines. They become outdated and convey no value. (Source: Jay Schwedelson, Episode #167)
• Don't write bullet points without "so you can" clauses. Features listed in isolation don't connect to the recipient's actual goals. (Source: Sheri Otto, Episode #247)
• Don't use generic industry buzzwords ("best-in-class," "advanced workflow," "emerging technologies"). These signal lazy or AI-generated copy and fail to demonstrate industry understanding. (Source: Sheri Otto, Episode #247)
• Don't write subheads that describe features rather than reader benefits. Subheads should answer "why should I care?" (Source: Samar Owais, Episode #247)
• Don't write emails to a broad audience. Every email should be written to one specific person or persona. (Source: Samar Owais, Episode #247)
• Don't include multiple CTAs pointing to different destinations. One email, one CTA type. (Source: Samar Owais, Episode #247)
• Don't write text blocks longer than four lines. They appear overwhelming, especially on mobile. (Source: Jay Schwedelson, Episode #241)
• Don't use AI as your primary copywriter without training and human oversight. Generic AI output lacks the specificity and personality needed to stand out. (Source: Sofia Silva, Episode #247)
