How Long Should A Marketing Email Be?

Email remains one of the most reliable and cost-effective ways to connect with your audience.

But here’s a question that keeps marketers—and business owners—up at night: How long should a marketing email be?

Finding that sweet spot is crucial. Too long, and readers might lose interest (or never even click “Open”); too short, and you risk failing to convey your message or missing an opportunity to build trust.

In this post, we’ll dive into why email length matters, what research says, and how you can strike the right balance to drive engagement and conversions.

Along the way, we’ll show you how MailDrip, our email marketing platform designed for creators and personal brands, simplifies this entire process so you can focus on crafting compelling content and let automation handle the heavy lifting.

Why Email Length Matters

Attention Spans Are Short

Inbox overcrowding is real. According to a HubSpot study on optimal email length, the average reader only spends about 11 seconds glancing at an email before deciding to read or delete it. If your email doesn’t grab—and keep—their attention quickly, it’s gone.

Mobile Is King

Over 60% of emails are opened on mobile devices. Longer emails often require more scrolling, which can frustrate readers who just want to get to the point. A concise, scannable format makes it easier for on-the-go readers to digest your message.

Delivering Value vs. Wasting Time

Email marketing isn’t about bragging about your latest product; it’s about delivering value—whether that’s education, inspiration, or an exclusive offer.

Striking the right length ensures you respect your reader’s time while still providing enough context to build trust and prompt action.

When you understand why length matters, tailoring your emails becomes a strategic advantage rather than guesswork. And that’s where having the right tools—like MailDrip—comes in.

With MailDrip’s intuitive templates and analytics, you can test varying lengths, measure click-through rates, and let the data guide your content strategy.

The Science Behind Ideal Email Length

Research into attention, reading patterns, and conversion metrics has given us some high-level benchmarks to guide your email length decisions:

Short & Sweet Emails (50–125 words)

• Often used for promo blasts, flash sales, or quick updates.
• According to a WordStream analysis of over 40 million marketing emails, messages under 125 words tend to have the highest click-through rates (around 51%).
• Pros: Quick to write, easy to scan, great for mobile users.
• Cons: Hard to provide depth or storytelling—best suited for audiences already familiar with your brand.

Mid-Length Emails (150–200 words)

• This range often hits a sweet spot for newsletters or product announcements.
• The Campaign Monitor guide suggests that 150–200 words let you include a clear value proposition, a brief explanation, and a single call-to-action (CTA) without overwhelming readers.
• Pros: Enough room to build a quick narrative or highlight key benefits; still concise.
• Cons: Requires disciplined writing to avoid fluff.

Longer-Form Emails (250+ words)

• Often used for in-depth educational content, case studies, or major product launches.
• While longer emails can work—especially if you have a highly engaged, niche audience—open rates and engagement tend to drop if readers don’t immediately see the value.
• When you need to go deeper, consider breaking content into a mini-blog format with clear subheads, bullet points, and inline links so readers can jump to the sections they care about.

Ultimately, the “ideal” length depends on your goals. Are you simply driving a flash sale? A shorter email with a punchy subject line will work best. Are you nurturing a new lead with educational content? A longer, story-driven email may be more appropriate.

The key is to test different lengths, measure engagement (opens, clicks, replies), then iterate—something MailDrip’s built-in analytics makes effortless.

Matching Email Length to Your Audience and Goals

1. New Subscribers vs. Loyal Fans

• New Subscribers: They’re just getting acquainted with your brand. A mid-length email (around 150–200 words) that introduces your brand’s unique value, sets expectations for future emails, and includes a friendly welcome note can build early rapport.
• Loyal Fans: If someone has been opening and clicking your emails for months, they may appreciate deeper insights—think exclusive behind-the-scenes stories or advanced tutorials, which might run 250+ words. Because they’re already invested, they’re more likely to skim a longer email if it’s relevant.

2. Transactional vs. Promotional vs. Educational

• Transactional Emails (e.g., order confirmations, password resets) should be succinct. Readers want clarity and reassurance, not extra copy. Keep these under 100 words, with clear headings and a single CTA (if any).
• Promotional Emails (e.g., flash sales, product launches) can be anywhere from 50–200 words, depending on complexity. If you’re launching a brand-new product, you might need more room to explain benefits, showcase testimonials, and guide them to a landing page. If it’s a one-day 20% off sale, a 75-word email with a bold “Shop Now” button often suffices.
• Educational Emails (e.g., newsletters, tutorials, case studies) typically run 200–300+ words. But structure is everything: use subheadings, bullet points, and visuals (images or GIFs) so readers can skim and click through to your blog or video if they want more detail.

3. Personalization and Segmentation

Segmenting your list based on behavior, demographics, or purchase history allows you to tailor email length more precisely.

For example, if you know a segment prefers video content, you might send a shorter synopsis (100 words) with a video thumbnail linking to a deeper explanation.

MailDrip’s segmentation tools let you create these micro-audiences and effortlessly deliver the right length to the right people.

Anatomy of an Effective Email (No Matter the Length)

Whether you’re writing a 75-word flash sale email or a 300-word educational newsletter, the same core principles apply:

Subject Line (5–8 words)

• Keep it concise: The subject line is the first—and sometimes only—chance to convince someone to open.
• Include a clear benefit or sense of urgency: “50% Off Ends Tonight,” “New Tips to Boost Your Productivity.”

Preview Text (35–50 characters)

• Acts as a secondary subject line. Use it to elaborate on your subject or highlight an additional benefit.

Greeting (10–15 words)

• Personalize when possible: “Hi [First Name],” rather than a generic “Hello,” helps build rapport.

Body Copy

• Opening Sentence: Hook the reader immediately—ask a question, share a surprising stat, or promise a quick tip.
• Main Message: Convey your value proposition. If it’s short, get straight to the point. If it’s longer: break it into 2–3 paragraphs with bold subheads.
• Visuals or GIFs (Optional): A well-placed image or GIF can grab attention and break up text. Just make sure it doesn’t slow down load times.

Call-to-Action (CTA)

• Whether it’s a button or a text link, make it prominent. Use action-oriented language: “Start Your Free Trial,” “Read the Full Case Study,” “Claim 20% Off.”

Signature and Footer

• Keep your signature brief, including name, title, and a small logo if relevant. The footer should have unsubscribe links, social icons, and legal disclaimers.

Structure is particularly important for longer emails. If you exceed 200 words, consider:

• Bullet Points: Highlight 3–5 key benefits or steps.
• Subheadings: Let skimmers jump to the section they care about.
• Short Paragraphs: Keep paragraphs to 1–2 sentences each—this improves readability, especially on mobile.

With MailDrip’s drag-and-drop editor and prebuilt templates, you don’t have to worry about coding or design.

Simply pick a layout that matches your desired length and let our platform scale images, buttons, and text blocks automatically for mobile responsiveness.

Industry Benchmarks: What the Data Tells Us

While the exact “perfect” length varies by audience and goal, several industry benchmarks provide useful guidelines:

• Open Rates vs. Word Count: A Litmus study found that emails between 50–100 words averaged open rates around 37%, whereas emails above 200 words saw open rates dip closer to 29%.
• Click-Through Rates (CTR): Emails under 125 words held a CTR of around 51%. But when word count climbed above 200, CTR fell to about 44%.
• Conversion Rates: Promotional emails around 200 words often hit the highest conversion rates, likely because they provided enough context to persuade readers without overwhelming them.
• Read Time: The average adult reads around 200–250 words per minute. So a 100-word email takes under 30 seconds to read. Keeping emails “five seconds or less” (roughly 15–25 words) can work for super-short promotions, but that’s the exception rather than the rule.

Key takeaway: Use these benchmarks as starting points, not hard rules. Different industries and audiences can deviate significantly.

If you sell B2B software, your newsletter might be 250–300 words because your audience expects in-depth insights. If you’re an indie artist promoting a new single, 75 words with a link to a 30-second preview often suffices.

MailDrip’s reporting dashboard makes it easy to compare open and click metrics across email lengths—so you can find your own “sweet spot” and double down on what resonates.

How MailDrip Helps You Nail Your Email Length

Crafting the perfect email length isn’t just about word counts—it’s about workflow, testing, and analytics. That’s where MailDrip shines:

Prebuilt, Mobile-Optimized Templates

Drip Campaign Builder

• If you’re nurturing leads over time, you can set up automated sequences where each email’s length and content build upon the previous one. For example, send a short, 75-word “welcome” email on Day 0, then a mid-length (150-word) “getting started” guide on Day 3, followed by a longer, 250-word “case study” email on Day 7.
• You can A/B test different lengths within the same sequence: send 100-word versus 200-word versions of Email #2 to see which attracts more clicks. MailDrip tracks all metrics, so you know precisely how email length influences behavior.

Pay As You Go (PAYG) Flexibility

• Whether you send a daily flash update (very short emails) or a monthly in-depth newsletter (longer emails), you only pay for what you send. No confusing tiered pricing or surprise overage fees.
• This means you’re free to experiment: send some short, some long—see what works—and only pay for the actual emails that land in inboxes.

Detailed Analytics and Heat Maps

• Beyond open and click rates, MailDrip’s heat-map feature shows you exactly where subscribers click and how far they scroll. If you notice readers dropping off halfway through your 300-word email, that’s a clear signal to shorten it or restructure with stronger subheads.
• Over time, you’ll gather data on average read times, engagement by segment, and performance differences between short vs. long emails—information you can’t easily capture elsewhere.

Free Image Hosting & Drag-and-Drop Editor

• Sometimes an image can replace a hundred words (think infographics or product screenshots). Our free image hosting ensures your emails load quickly, even if they’re longer in copy.
• With the drag-and-drop editor, you can intersperse images, GIFs, and text blocks to break up large chunks of text—helping you craft a “long” email that still feels easy to digest.

All of these features work together so you never have to guess. Start with a template optimized for your desired word count, let MailDrip handle the responsive design, and use analytics to refine over time. It’s the simplest way to ensure your emails are “just right” every time.

Preview Text: Learn how to fix them in under 5 minutes.

Hello there,

You’ve put hours into building your email list… but are you sabotaging your results? Here are five common mistakes we see:

1. Neglecting the Subject Line: If it’s not compelling, people won’t open. Keep it under 50 characters—think curiosity, specificity, or urgency.
2. Overloading With Text: Wall-to-wall paragraphs can scare readers away. Aim for 150–200 words for standard newsletters, and break text into 2–3 short paragraphs with bold subheads.
3. Skipping a Clear CTA: If readers don’t know what to do next, they won’t do anything. Make your primary CTA button stand out with action verbs—e.g., “Start Your Free Trial.”
4. Ignoring Mobile Optimization: Did you know over 60% of people read emails on their phones? Use responsive templates to ensure readability on every device.
5. Forgetting to Test: A/B testing subject lines, preview text, and email length can reveal what resonates most.

By addressing these five points, you’ll see a noticeable uplift in engagement. If you’d like a ready-to-use template to fix these issues, check out our Email Health Check Kit.

Frequently Asked Questions (FAQs)

1. Is there a universal “best” word count for marketing emails?

No. While studies often cite 50–125 words as ideal for click-through rates, the “best” length depends on your audience, industry, and goals. Always test various lengths—MailDrip makes A/B testing this simple.

2. How do I decide between a short vs. long email?

Ask yourself: What’s the primary goal? If it’s a last-minute sale, keep it short (50–100 words). If you need to educate or tell a story, go longer (200–300 words) but use subheadings and bullet points to maintain readability.

3. Should I use images or GIFs in a short email?

Only if they add immediate value. In very short emails (under 100 words), a strong hero image or GIF can replace a paragraph of text, making your email more engaging. Be cautious not to slow load time—MailDrip’s free image hosting optimizes every file automatically.

4. What about plain-text emails vs. HTML?

Plain-text emails feel personable and often bypass spam filters more easily. However, they lack design elements (buttons, colors) that can improve CTAs.

For short, personal notes, a plain-text approach works. For promotional or educational emails, HTML with responsive design (like MailDrip’s templates) tends to drive higher engagement.

5. How often should I send emails, and does that affect length?

Send frequency and length go hand in hand. If you email daily, keep them under 100 words—your readers will appreciate brevity.

Weekly newsletters can be 200–300 words.

Monthly roundups might span 400+ words if you’re aggregating top content or announcements. MailDrip’s scheduling feature helps you plan the perfect cadence for your audience.

Conclusion

At the end of the day, there is no “one-size-fits-all” answer to How long should a marketing email be? It’s a moving target shaped by your audience’s expectations, the purpose of the email, and where they are in the customer journey.

The good news? You don’t have to navigate this on your own. With MailDrip, you get access to mobile-optimized templates, intuitive drag-and-drop editing, and robust analytics that let you test various lengths and see what truly performs.

Whether you’re sending a 75-word flash sale or a 300-word in-depth newsletter, MailDrip handles the technical side—responsive design, deliverability optimization, and segmentation—so you can focus on crafting copy that resonates.
