The complete guide to enterprise email marketing in 2025

Enterprise brands must also balance eye-catching email designs and carefully crafted strategies with advanced security to protect customer data and meet regional regulatory requirements. Integrating email marketing solutions with existing tech stacks—from ecommerce platforms and CRMs to analytics platforms—only adds to this challenge.

Most email platforms aren’t built for this level of complexity. But Klaviyo’s enterprise solutions help brands manage security, compliance, and smart segmentation—all from one platform.

Strategy means nothing without the right tech to execute it. You can’t run enterprise-level email marketing campaigns with platforms built for small businesses or individual marketers—they lack scalability, not to mention advanced features and services. 

When considering enterprise email marketing platforms, focus on how they: 

• Scale with you. Enterprise email marketing solutions enable hyper-personalization at scale by segmenting customers based on any data point and automating personalized emails based on customer behavior and preferences. 

• Integrate with your tech stack. Platforms must sync with existing marketing, sales, analytics, and customer service systems to accurately target and personalize emails. Klaviyo’s 350+ platform integrations unify your data and capture real-time and historical customer interaction data.

• Provide enterprise-grade service and support. 24/7 email and live chat support, a dedicated customer success manager, and a solutions architect are essential for optimizing deliverability and automation.

• Cut costs through solution consolidation. Managing multiple tools for email marketing, automation, and analytics increases costs. Klaviyo centralizes these functions, reducing tech stack complexity and lowering TCO while boosting ROI. Helen of Troy, for example, reduced TCO 40% after switching to Klaviyo.

• Put marketers in control. Modern platforms support B2C email marketing growth, put marketers in control, and enable personalized customer experiences without heavy tech team involvement. 

• Rank in user satisfaction. Klaviyo, for example, earns its position as a Leader in G2’s Grid® for marketing automation software. Users love the platform for its easy integrations, automated complex workflows, and ability to personalize enterprise email campaigns at scale.

You miss out on valuable customer insights when customer data is spread across various platforms. The key to great email marketing campaigns is integrating data from your CRM, sales, customer service, and analytics platforms into unified customer profiles.  

A customer data platform (CDP) like Klaviyo Data Platform (KDP), the CDP built in to Klaviyo B2C CRM, eliminates data siloes and centralizes all customer data into one profile. It captures every click, purchase, and interaction as a single source of truth for all your teams. With all touchpoints pulling information from the same customer profile, email segmentation and personalization become more powerful. 

Advanced KDP, meanwhile, empowers you to uncover deep insights through sophisticated techniques like RFM analysis, funnel analysis, product analysis, audience performance, and custom properties.

Collect zero- and first-party data—the richest source of understanding customer behavior, preferences, and intent—to build customer profiles. Focus on gathering data from various touchpoints—website interactions, in-store visits, and purchase history—to better align email content with customer interests.

Want to drive higher engagement and growth with minimal effort? Then scaling your email automations is crucial.

Customer journey mapping helps you create personalized campaigns that guide customers from interest to loyalty. 

With Klaviyo, you can visualize customer lifecycles and optimize every touchpoint, like sending reminders after key moments like product views or abandoned carts. 

Multi-touch attribution, meanwhile, tracks customer interactions across channels, providing the insights needed to drive cross-channel orchestration and ensuring you deliver consistent, personalized messages across email, SMS, and more—perfectly timed and based on real-time actions.

With Klaviyo flows, automation is simple. A drag-and-drop builder, AI-powered flows, and over 60 customizable templates make it easy to create high-impact automations that drive immediate and long-term results. Examples include: 

• Abandoned cart recovery: An automated sequence of reminders and incentives encourages customers to complete purchases. 

• Post-purchase nurturing: Personalized follow-ups, product recommendations, and exclusive offers ensure customers feel valued after their transaction, turning one-time buyers into loyal brand advocates. 

• Re-engagement campaigns: Customized win-back flows help you re-engage inactive customers with tailored offers and messaging.

Popular clothing and accessories brand DKNY manages over 1.2 million active subscribers with hyper-targeted, automated workflows. With personalization based on AOV, tailored welcome messages, and relevant product recommendations, flows drove 30% of their Klaviyo-attributed value in just 3 months.

“Klaviyo flows are efficient conversion tools that ensure emails really align with people’s interests and their actions on the website,” says Griffin Hawkinson, director of CRM and loyalty at AM Retail Group. “Our goal now is to see if there’s more we can do with them, whether it’s leveraging predictive analytics or more profile attributes.”

Here, see how DKNY’s promotional email includes items someone may have already looked at—transforming what might otherwise be received as a general marketing email into a curated collection of items the recipient is more likely to be interested in.

Since most B2C consumers shop on mobile websites, according to our future of consumer marketing report, go mobile-first with your email design strategy. Start by building out on-brand email templates. This makes the design process faster and ensures emails reflect your brand’s identity—without reinventing the wheel every time.

And as more and more shoppers actively seek out brands that reflect their values, according to our future of consumer marketing report, don’t shy away from infusing your emails with your brand’s principles through design and content. 

Here are some email design and content best practices to follow:

• Create master templates with brand standards, like font, font size, and styling.

• Design for accessibility and responsiveness across any email client or device.

• Strategically incorporate CTAs, but don’t overwhelm your readers.

• Use mobile-first email design.

• Carefully balance visuals and text.

• Use design to highlight pain points or reader interests.

• Always include an unsubscribe link.

• Make your footer a resource, and include your brand mission, ways to reach out to customer service, and social media follow buttons.

Here’s another great example from DKNY. This email captures their brand identity, while also communicating their values to their audience. It also includes a simple CTA and a mobile-friendly design with clear shop links to different categories on their website.

Personalization is essential for driving engagement and conversion. But especially for enterprise brands, it needs to be about efficiency.

Take it from modern wardrobe and home brand Jenni Kayne. By using a less-is-more email strategy, they went from a high-volume approach, sending emails as often as 3x per day, to sending more strategic, interest-based campaigns based on purchase history and customer data. This shift, which felt more aligned with their luxury experience, contributed to a 14.5% YoY increase in revenue.

Meal delivery service provider Daily Harvest, meanwhile, went the tech stack efficiency route. Before, the team wasn’t able to move very quickly. They were slowed down by a system that required a developer for any type of email customization. 

The team consolidated 4 ecommerce tools into Klaviyo and reduced tech costs by 18%—and they gained the ability to create new flows and segments quickly, without developer support. Now, the team can easily target customer segments with personalized messaging, at scale.

Without context, data is just noise. Let’s see how you can get the most out of your data to fuel your future strategy.
