Why Email Marketing Still Matters in 2025
Despite the constant emergence of new marketing channels, email remains the workhorse of digital marketing. With an average ROI of $36 for every $1 spent, email marketing continues to outperform most other channels. But achieving these results isn’t as simple as building a list and blasting out messages.
At Brand Llama, we’ve seen firsthand how strategic email marketing transforms businesses—and how poor practices can damage brand reputation. This comprehensive guide will walk you through proven best practices for building, maintaining, and engaging your email list effectively.
Building Your List the Right Way
The Case Against Purchased Lists
It’s tempting to jumpstart your email marketing by purchasing a list. After all, building an organic list takes time. However, purchased lists create more problems than solutions:
- Lower deliverability rates as ISPs flag unfamiliar senders
- Potential violations of anti-spam laws and regulations
- Damage to your sender reputation and domain authority
- Poor engagement metrics that can impact your entire email program
Instead, focus on these organic list-building strategies:
Effective Signup Methods
Strategic Website Forms
Place signup forms strategically throughout your website—not just in the footer. Consider:
- Exit-intent popups that appear when visitors are about to leave
- Slide-ins that appear after visitors have engaged with content
- Embedded forms within your most popular content
- Header banners for limited-time offers
The key is finding the balance between visibility and user experience. Test different approaches to see what works best for your audience.
Value-Driven Lead Magnets
People rarely give their email address without getting something valuable in return. Effective lead magnets include:
- Industry reports or white papers
- Free tools or templates
- Exclusive discounts or early access
- Educational content like webinars or mini-courses
For example, a manufacturing company might offer a guide on “5 Ways to Reduce Supply Chain Costs,” while a B2C brand might provide a discount code for first-time purchases.
Leverage Your Existing Touchpoints
Don’t overlook opportunities to collect emails through:
- Transaction confirmations
- Customer service interactions
- Event registrations
- Social media channels
- In-person events with digital signup options
The Welcome Sequence
Your relationship with subscribers begins the moment they join your list. A well-crafted welcome sequence helps set expectations and build engagement:
- Immediate confirmation: Send a thank-you message confirming subscription
- Value delivery: Provide the promised lead magnet or incentive
- Introduction: Share your brand story and what subscribers can expect
- Engagement prompt: Invite subscribers to take a small action (follow on social, browse popular content, etc.)
Well-designed welcome sequences can see open rates of 50-60%, making them your best opportunity to make a strong first impression.
Maintaining a Healthy Email List
List maintenance isn’t the most exciting part of email marketing, but it’s crucial for long-term success. Think of it as regular exercise for your email program—it keeps everything running efficiently.
Regular List Cleaning
Periodically removing inactive subscribers may seem counterintuitive—after all, isn’t a bigger list better? Not necessarily. Here’s why regular cleaning matters:
- Improves deliverability rates
- Increases engagement metrics
- Reduces email service provider costs
- Provides more accurate performance data
Consider implementing a sunset policy that automatically removes subscribers who haven’t opened or clicked in a defined period (typically 6-12 months). Before removal, run a re-engagement campaign to give them an opportunity to stay active.
Smart Segmentation Strategies
Segmentation allows you to send more relevant content to different subscriber groups. Effective segmentation criteria include:
- Demographic data: Location, industry, company size, etc.
- Behavioral data: Past purchases, website activity, email engagement
- Subscription source: How they joined your list
- Content preferences: Topics they’ve shown interest in
Even basic segmentation can significantly improve performance. For instance, separating active and less active subscribers allows you to send re-engagement campaigns to the latter group without annoying your most loyal readers.
Testing and Optimization
Continuous improvement should be part of your email maintenance routine. Regularly test:
- Subject lines
- Send times and frequencies
- Content formats
- Call-to-action placement and wording
Make testing a habit rather than a one-time event. Small, incremental improvements compound over time to create significant results.
Engaging Your Audience Effectively
Building and maintaining your list is just the foundation—engagement is where the real value happens.
Content That Connects
The most successful email campaigns deliver genuine value to subscribers. This looks different for every business, but might include:
- Educational content that solves real problems
- Industry insights and trend analysis
- Product updates with clear benefits (not just features)
- Stories that illustrate your impact or values
At Brand Llama, we’ve found that blending educational content with strategic promotions yields the best results. Aim for an 80/20 ratio: 80% valuable content, 20% promotional material.
Personalization Beyond First Names
Modern personalization goes far beyond “Hi [First Name].” Effective personalization strategies include:
- Content recommendations based on past engagement
- Targeted offers based on purchase history
- Lifecycle-specific messaging (new subscribers vs. loyal customers)
- Behavior-triggered emails (abandoned carts, product views)
The goal is to make each subscriber feel like the email was created specifically for them, even when you’re sending to thousands.
Design for Readability and Action
Email design should prioritize readability and clear calls to action:
- Use short paragraphs and plenty of white space
- Employ bullet points for scannable content
- Ensure your primary CTA stands out visually
- Design with mobile users in mind (over 60% of emails are opened on mobile devices)
- Use a consistent, branded template that recipients recognize
Remember that fancy designs mean nothing if they distract from your message or call to action.
Staying Compliant and Building Trust
Email marketing regulations continue to evolve globally. Compliance isn’t just a legal requirement—it’s a trust signal for your audience.
Key Regulations to Know
- CAN-SPAM Act: Requires unsubscribe options, physical address, and truthful subject lines
- GDPR: Mandates explicit consent, privacy policies, and data rights for EU citizens
- CCPA/CPRA: Provides California residents with data rights similar to GDPR
Stay updated on these regulations through resources like our GDPR guide.
Trust-Building Practices
Beyond compliance, these practices build subscriber trust:
- Be transparent about how you’ll use their data
- Set clear expectations about email frequency
- Make unsubscribing simple and honor requests immediately
- Deliver on the promises made during signup
