Email marketing remains one of the most effective digital marketing channels for building customer relationships, nurturing leads, and driving conversions. Even with the rise of social media, AI-driven ads, and messaging platforms, email continues to offer an unparalleled return on investment. But to achieve results in 2025, businesses must adapt to evolving consumer expectations, data privacy regulations, and shifting inbox behaviors.
This guide explores the essential email marketing best practices every brand should follow in 2025. From list building and personalization to automation and compliance, these strategies will help you create impactful campaigns that improve engagement and generate more revenue.
How Does Email Marketing Shape Strategy & Preparation?
The foundation of a successful Klaviyo email marketing strategy lies in planning. Without a strong strategy, campaigns risk low engagement, high unsubscribe rates, or even being flagged as spam. Preparation involves understanding your audience, segmenting lists effectively, and creating a communication cadence that matches customer behavior.
1. Know Your Audience
The first best practice is understanding who you’re emailing and why. Blindly sending bulk messages is ineffective in 2025. Customers expect brands to recognize their preferences and deliver value in every email.
- Conduct surveys and collect customer feedback.
- Use website analytics and purchase history to identify patterns.
- Build customer personas that reflect demographics, buying habits, and interests.
By knowing your audience, you can create tailored campaigns that resonate and reduce the risk of unsubscribes.
2. Personalization and Segmentation
Generic newsletters are outdated. Today’s email marketing best practices emphasize personalization, not just adding a first name in the subject line, but curating content based on customer data. Segmentation plays a key role in achieving this.
- Segment lists by behavior (purchase frequency, engagement levels, browsing history).
- Send personalized product recommendations based on past purchases.
- Use predictive analytics to anticipate customer needs.
For example, an ecommerce store could send one customer a loyalty discount on skincare while targeting another with new arrivals in fitness gear, because their buying behavior differs.
3. Timing and Frequency
Another critical element in preparation is identifying the right time and frequency to email your subscribers. Overloading customers leads to unsubscribes, while infrequent emails risk losing engagement.
- Test different days and times using A/B testing.
- Consider audience location and time zones.
- Allow subscribers to choose their preferred frequency (weekly, monthly, etc.).
Optimizing timing ensures your emails are opened and clicked instead of ignored.
What Are the Email Marketing Best Practices for Building & Managing Your List?
A high-quality email list is the foundation of successful campaigns. In 2025, list building is less about quantity and more about quality and compliance.
- Use opt-in forms across your website, blog, and social media.
- Offer value in exchange for sign-ups, such as discounts, eBooks, or exclusive content.
- Avoid purchased lists, which harm deliverability and often violate regulations.
- Regularly clean your list by removing inactive subscribers and bounced emails.
A well-managed list ensures high deliverability and engagement, which are key to long-term results.
Which Email Marketing Improve Design & Content?
Once you’ve built a list, your next focus is design and content. Customers expect visually appealing, mobile-optimized emails that deliver value in just a few seconds.
Compelling Subject Lines
The subject line is the first impression, and often the deciding factor in whether an email gets opened. Best practices include:
- Keep subject lines under 50 characters.
- Use action-oriented words.
- Avoid spammy terms like “free” or “guaranteed.”
- Test emojis carefully to match your audience’s tone.
For example: “Your personalized skincare routine is waiting” is more compelling than “Skincare products for you.”
On-Brand Design and Clear Copy
An email should reflect your brand identity while keeping readability in mind.
- Use clean layouts with plenty of white space.
- Ensure mobile responsiveness, over 60% of emails are opened on mobile devices.
- Include clear CTAs (call-to-actions) such as “Shop Now” or “Learn More.”
- Maintain consistency in fonts, colors, and voice.
Clear copy paired with an attractive design enhances user experience and boosts conversion rates.
What Are the Email Marketing Best Practices for Running Campaigns?
Running effective campaigns requires a balance between creativity and analytics. To optimize performance:
- Always define your goal (sales, engagement, lead nurturing).
- A/B test subject lines, CTAs, and visuals.
- Track key metrics, open rates, click-through rates, and conversions.
- Monitor competitor campaigns for inspiration.
By treating every campaign as a learning opportunity, you can refine your email marketing strategy and increase ROI over time.
Which Email Marketing Best Practices Should You Use for Automation?
Automation is one of the most powerful tools in modern email marketing. It enables brands to engage subscribers at the right moment with minimal manual effort.
Welcome Series
A welcome series sets the tone for your relationship with subscribers. Best practices include:
- Send the first welcome email within 24 hours of sign-up.
- Introduce your brand, values, and what subscribers can expect.
- Offer a small incentive (e.g., 10% discount) to encourage the first purchase.
Abandoned Cart Recovery
Cart abandonment rates are still around 70%. Automated recovery emails remain one of the top-performing campaigns.
- Send reminders within a few hours of abandonment.
- Include product images and reviews.
- Offer a limited-time discount to drive conversions.
Post-Purchase & Win-Back Flows
Retaining customers is cheaper than acquiring new ones. Post-purchase flows encourage loyalty and repeat sales.
- Thank customers and confirm their orders.
- Provide product usage tips or upsell complementary items.
- Re-engage inactive subscribers with win-back emails offering exclusive deals.
How Do Email Marketing Improve Deliverability & Compliance?
Even the best campaigns fail if emails never reach the inbox. Deliverability and compliance are therefore critical.
- Authenticate your emails with SPF, DKIM, and DMARC.
- Maintain good list hygiene by removing inactive contacts.
- Avoid spam triggers in subject lines and content.
- Comply with regulations like GDPR and CAN-SPAM by always including an unsubscribe link and respecting user preferences.
Strong deliverability ensures your emails actually generate engagement instead of being lost in spam folders.
What Advanced Email Marketing Support a Multichannel Strategy?
Email doesn’t exist in isolation. The most successful strategies in 2025 integrate email with other marketing channels.
- Combine email with SMS marketing for urgent updates and promotions.
- Leverage social media retargeting based on email engagement.
- Integrate email with content marketing, such as newsletters that promote blogs, podcasts, or videos.
- Use AI tools to create dynamic content and predictive recommendations across multiple platforms.
By aligning email with broader marketing efforts, you create a seamless customer journey that improves brand loyalty.
