Email Newsletter Design: Crafting Engaging Emails
Most businesses are leaving money on the table with every newsletter they send. Not because their product is terrible. Not because their audience doesn't care. But because they're making one catastrophic mistake that's costing them 50-80% of their potential revenue.
Your subscribers don't care about your email. They care about themselves.
The average person gets 121 emails daily and opens just 18%. When someone opens your email, you have approximately 3 seconds before they decide whether to read it or trash it.
Three. Seconds.
In those three seconds, they're subconsciously asking one question: “What's in it for me?”
The businesses that are dominating their markets have cracked this code. They understand that email design isn't about pretty templates or clever subject lines—it's about creating an irresistible value exchange where your reader feels they'd be insane NOT to keep reading.
I will show you how to craft emails that get opened and acted upon—the same framework that helped our clients generate millions in additional revenue last year alone…
- Understanding your audience's needs increases email engagement and revenue potential significantly.
- Clear goals and effective segmentation enhance the relevance and performance of your newsletters.
- Mobile-first design and compelling content are crucial for capturing readers' attention quickly.
- Regular A/B testing and metric analysis are essential for optimising email campaigns over time.
Laying the Groundwork: Key Decisions Before Designing Your Newsletter

Before diving into design, several critical decisions impact your newsletter's effectiveness. Carefully consider your goals, brand, segments, timing and frequency to inform creative direction.
Identifying Goals and Metrics
Like any marketing initiative, clearly articulate your newsletter's goal.
Potential goals include:
- Drive traffic to your website
- Increase brand awareness
- Grow your subscriber list
- Generate more sales
- Improve customer retention
With goals defined, identify key metrics to track performance over time, like open rates, click-through rates (CTRs), and conversion rates. Benchmark against industry averages to evaluate how your newsletter stacks up.
Understanding Your Brand
Email design should align with your broader brand identity and positioning. Using brand colours, fonts, imagery, tone, and messaging builds recognition and trust with subscribers.
Map out your brand guidelines regarding:
- Typography
- Colour palette
- Imagery style
- Tone and voice
- Key messages and mission
Adhering to guidelines ensures a cohesive experience across channels while allowing creativity within constraints.
Best Practices for Personalisation in Email Newsletters
Personalisation in emails can significantly increase engagement.
Using recipient names in subject lines boosts open rates.
Tailoring content based on past purchases enhances relevance.
Segmenting subscribers by behaviour or interests ensures each email resonates.
These techniques create a personalised experience, encouraging higher interaction levels.
Segmenting Your List
Segment your subscriber list based on user personas, interests, behaviours, demographics, purchase history, and more. Build targeted lists like:
- Active customers
- Lapses customers
- Prospects
- Discount seekers
Create tailored emails catered to each group. Segmentation boosts open and click-through rates as recipients receive content they care about.
Personalisation is key in segmentation strategies.
Segment your audience using demographic data, browsing history, and engagement patterns.
Customise emails based on past interactions for a more relevant reading experience.
This approach increases open rates and enhances subscriber loyalty, reinforcing positive brand impressions.
Finding Your Newsletter’s Sweet Spot for Timing and Frequency
Overwhelm subscribers with too many emails, and they’ll tune you out or unsubscribe. Too few, and they’ll forget about you. Find your “sweet spot” for timing and frequency.
Frequency
Typical business newsletters send:
- Weekly
- Every two weeks
- Monthly
- Quarterly
Test to see what resonates best with your audience based on preferences and industry norms.
Timing
Use analytics to determine when your subscribers are most engaged. Pay attention to:
- Day of week
- Time of day
Adjust send times to maximise open and interaction rates.
Designing On-Brand, Visually Appealing Emails

With your strategy defined, kickstart designing your email creatively—Prioritise visual design for skimmability and scannability.
Grabbing Attention With Compelling Subject Lines
Craft compelling, benefit-driven subjects since subscribers glance at subject lines to decide whether to open an email. Practical topics connect to readers’ needs and interests.
⛔ Boring: New products available!
✅ Intriguing: Instant energy – shop new wellness products
Subject line length sweet spot:
- 45-60 characters
Other best practices:
- Speak to benefits and value
- Use numbers, e.g. “5 new styles.”
- Leverage urgency, e.g. “24-hour flash sale!”
- Ask questions
- Use personalisation
- Test different options
Continually A/B test to optimise subject lines over time.
Aligning With Brand Guidelines
Follow brand guidelines when selecting:
Colour Palette
- Primary brand colours in headlines, call to action (CTAs), and key backgrounds.
- Accent colours to highlight or contrast information
⛔ Avoid jarring color clashes
✅ Complementary shades create visual harmony
Typography
- Feature main brand fonts in headlines and body text
- Use accent fonts sparingly for contrast
⛔ Limit to 2-3 fonts maximum
✅ Establish visual hierarchy from headlines to body
Imagery
- Photos and graphics should align with brand style regarding colour, tone, and composition
⛔ Generic stock images look disjointed
✅ Custom images reinforce branding
Messaging
- Echo brand messaging and persona in the email’s tone and voice
✅ Consistency across channels strengthens brand identity
Optimising Email Structure
Well-structured emails enhance the user experience. Best practices include:
- Clear hierarchy: Use fonts, colours, and whitespace strategically to create a hierarchy emphasising what matters most
- Single column: One-column layouts drive better completion rates on mobile
- Prominent CTA placement: Place CTAs early and repeat throughout to facilitate desired actions
- Readable line length: 45-75 characters per line
- Chunky paragraphs: 3-4 sentences max per paragraph
- Whitespace: Negative space prevents clutter and creates breathability
- Scannability: Use bullets, numbers, headers, and formatting techniques allowing readers to scan and skim
Equip your emails with responsive elements for aesthetic consistency across devices.
Test emails in multiple mobile environments to ensure compatibility.
Include succinct headlines and concise calls to action to maintain engagement, considering mobile users favour brevity and visual appeal.
Importance of Mobile-First Design in Newsletters
Mobile-first design is essential given the rise of mobile email usage.
Use single-column layouts for better readability.
Ensure buttons are touch-friendly and content loads quickly.
Short, direct text suits small screens, keeping the reader's attention.
A mobile-optimised approach maximises engagement, no matter the device used.
Crafting Compelling Email Content

With design and structure squared away, shift focus to crafting captivating content.
Establishing Reasons to Care Upfront
Answer the reader immediately: “What’s in it for me?” Summarise value propositions like savings, convenience, exclusives, or solutions early on.
Leverage data to personalise content further.
Use adaptable elements based on user data, such as location-specific information or recommended products related to past purchases.
Automation can assist in handling these adjustments, enhancing the reader's experience and driving engagement.
Headline Formulas That Stop Scroll
Email headlines can make or break content. Use time-tested formulas to craft irresistible headlines:
- How to: Teach readers something helpful
- Listen up: Capture attention with imperatives
- You won’t believe it: Trigger curiosity
- Guess what: Build anticipation about sharing news
- Warning/Alert: Convey urgency with this format
- [Number] ways to: Appeal to impulse for listicles
- Compare/compared: Readers love comparisons
- Secrets of: Leverage exclusivity with revealing insider info
⚠️ Avoid clickbait deception solely for metrics
Scannable Body Copy
Written content should cater to shrinking attention spans with easy skimming and scanning. Tactics include:
Section Content Into Chunks
⛔ Giant block paragraphs overwhelm
✅ Focused sections make content digestible
Use Short Paragraphs
Limit paragraph length for quicker consumption.
⛔ 5+ sentences overloaded
✅ 2-3 lines ideal
Feature Bulleted or Numbered Lists
Breaking up blocks of text with lists improves readability.
✅ Vertical lists help readers scan
Add Subheaders
Subheads within sections enable the skimming of crucial info.
✅ Subheads function as in-text signposting
Use Bolding Strategically
Draw attention to important phrases or numbers that support key points.
✅ The juxtaposition contrasts against regular text
Include Whitespace Between Paragraphs
Cluttered content blends. Whitespace creates much-needed breathing room that supports skimmability.
Sparseness amid density improves retention.
✅ Negative space prevents textual claustrophobia
Captivating Imagery to Break Up Text
Imagery interspersed through copy reduces density and awakens visual senses.
⛔ Text-heavy emails bore recipients
Choose imagery playing to emotional appeals:
- Happiness
- Trust
- Anticipation
- Belongingness
✅ Photos and graphics boost engagement when relevant and high-quality
Photography best practices:
- Candid > staged
- Real people > models
- Natural light > artificial light
- Minimal filters on photos
Drive Actions With Well-Crafted CTAs
Calls to action transform engagement into desired customer behaviour.
Effective CTAs include:
- Clarity on next steps
Avoid vague directives. Explicitly state the action sought.
- Sense of urgency
Imparting urgency taps into FOMO, motivating desired actions.
- Value highlighting
Emphasise the benefits readers receive from taking action.
- Prominent placement
Prime real estate like header, body, and footer improves visibility.
- Contrasting visuals
Make CTAs stand out sharply using colour, size, or icons.
- An active voice for firmness
- Imperatives convey confidence
- Specific vs. vague instructions
Optimising With A/B Testing
Regular A/B testing provides objective data revealing what content resonates best with your subscribers.
Potential tests:
- Subject line phrasing
- Headline variations
- Section priorities
- Text vs. visual content
- Length of content
- Call to action language
A/B testing compares variations to determine effectiveness.
Start by changing one element per test.
Adjust subject lines, imagery, or CTA placement.
Track metrics like open and click rates to assess performance.
Regular testing refines strategies and supports data-driven decision-making.
In addition to testing subject lines and imagery, explore split tests with email send times.
Testing delivery times can reveal when your audience is most engaged.
Analyse results to adjust when emails are sent, capturing higher engagement and click-through rates efficiently.
Optimising Delivery for Inboxes Everywhere

Crafting a visually striking newsletter means little if emails never reach recipients’ inboxes. Optimisation for successful delivery is essential for email campaigns.
Confirming Compliance With CAN-SPAM Act
The CAN-SPAM Act establishes legal requirements for commercial emails in the United States. Avoid violations carrying steep fines by including the following:
- Sender info and mailing address
- Opt-out mechanism
- Notice emails are ads
Stay compliant with thoughtful design choices.
GDPR Compliance for Email Marketing
GDPR affects any email marketing targeting users in Europe.
It requires explicit consent before sending marketing emails.
Provide an easy unsubscribe option to comply.
Data handling must remain transparent and secure.
Including a privacy policy link in emails keeps practices aligned with GDPR guidelines.
Getting Familiar With Major Email Clients
Understand display nuances across popular platforms like Gmail, Outlook, Apple Mail, and Yahoo.
Test your designs to identify formatting inconsistencies across email clients related to:
- Default fonts
- Line length
- Display of images
- Interaction with links
- Interpretation of CSS styling
Previewing across clients allows for addressing issues proactively.
Deliverability Factors and Challenges
Email deliverability depends on several factors.
Avoid using spam trigger words to improve inbox placement.
Maintain a clean list by removing inactive subscribers.
Consistent sending patterns establish reliability with email clients.
Implementing protocols like SPF and DKIM enhances sender verification and trust.
Monitor feedback loops from ISPs to identify any complaints and resolve issues promptly.
Encouraging subscribers to whitelist your email address can further mitigate unwanted bounces and enhance deliverability, keeping your sender's reputation intact.
Building a Positive Sender Reputation
Spam filters block emails from unknown senders to protect end users. Invest time upfront actively improving your sender reputation to prevent deliverability headaches.
Best practices include:
- Growing subscriber list organically from website sign-ups rather than buying or renting lists, which hurts sender score
- Sending consistently valuable content instead of overwhelming promotional emails, which leads recipients to report your messages as spam out of frustration
- Prioritising user preferences with granular opt-in and subscription management settings, putting subscriber experience first
- Monitoring sender reputation using tools providing visibility into critical metrics tied to good standing, like low spam complaints and high engagement
Streamlining With Email Service Providers
Rather than tackling deliverability challenges solo, email service providers offer helpful tools to improve inbox placement.
Collaborate with your email service provider to enhance deliverability rates.
Providers often offer tools for behaviour tracking and audience segmentation.
These tools help identify non-engaged users, allowing list cleansing to maintain an organic, interested subscriber base.
Key features include:
- Dedicated IP addresses with strong sender reputations
- Automated list cleaning identifying risky email addresses negatively impacting delivery
- Email authentication like SPF, DKIM and DMARC verify sender identity, reducing the likelihood of emails being marked as spam.
- Email testing capabilities identifying issues with spam filters or clients
- Access to expert support navigating challenges
The correct email service provider streamlines reaching inboxes.
Reviewing Key Performance Metrics
Consistently analyse metrics revealing how your emails stack up relative to benchmarks. Key indicators include:
Open Rates
- Measure of successfully delivered emails opened by recipients
- Benchmarks range between 15-25% open rate on average
⛔ Declining open rates suggest disinterest from subscribers
Click Through Rates
- Percentage of recipients clicking on one or more links after opening
- Average CTRs historically 3-5%
⛔ Low CTRs indicate irrelevant or unattractive content
Bounce Rates
- Percentage of undeliverable addresses out of total contacts
- Industry standards around a 2% bounce rate
⛔ High bounce rates hurt the sender's reputation
Unsubscribe Rates
- Percentage of recipients opting out over a given period
- Average rates historically 0.1 – 0.2%
⛔ Spikes may signal recipient fatigue from over emailing
Monitor metrics regularly, and troubleshoot declines before they become problems.
Tying Metrics to Business Impact
Ultimately, newsletter success means supporting organisational goals – driving website traffic, boosting sales, and improving retention.
Isolate newsletter impact on key business outcomes:
- Website sessions referred from email
- Online and offline revenue attributed to sends
- Lower customer churn rates
Continuous optimisation of creativity and delivery maximises business ROI.
