Overview of Klaviyo


Klaviyo isn't just a tool; it's a powerhouse that equips e-commerce businesses with the means to create and scale their marketing campaigns seamlessly. With features ranging from an intuitive email campaign builder to advanced automation, Klaviyo promises a holistic approach to customer engagement. Our team of experts embarked on a comprehensive exploration of Klaviyo to bring you real, helpful insights. Here, we'll delve into the key features that define Klaviyo's prowess in the field of e-commerce marketing.

Email Campaign Builder

The foundation of any successful email marketing strategy lies in the ability to craft compelling, visually appealing emails. Klaviyo's drag-and-drop template builder facilitates this process with remarkable ease. During our testing, we found ourselves drawn to the versatility it offered. Additionally, Klaviyo can be used for SMS marketing campaigns. We experimented with various themed templates and layout wireframes, and the results were striking.

In a real-world scenario, we simulated an e-commerce business launching a new product line. Using Klaviyo's template editor, we designed an email showcasing the products, complete with vibrant images and persuasive copy. The result? A visually stunning email that not only garnered high open rates but also translated into actual sales.

Email Marketing Automation


Automation is the cornerstone for efficient e-commerce brands, and Klaviyo doesn't disappoint. With 61 pre-made emails and e-commerce flows tailored for different campaign objectives, it's a game-changer. Our team tested it by setting up a mock cart abandonment flow. Klaviyo seamlessly integrated with the Shopify store, triggering a series of emails to potential customers who left items in their cart. The platform's ability to track UTM links and employ advanced filters allowed us to refine the flow further, ensuring that only the most relevant and targeted messages reached the recipients.

Sign-Up Form Builder

A robust email marketing strategy begins with building a solid subscriber base. Klaviyo's form builder offers a plethora of options, from pop-ups to full-page forms. Testing its capabilities, we created a mock pop-up form for a fashion retailer. With Klaviyo's customization options, we added elements like multi-select, coupon codes, and dropdown menus. The ability to target and tailor forms for specific customer segments further underscores its effectiveness.

Detailed Engagement Reporting


Understanding how your audience interacts with your emails is crucial for refining your marketing strategy. Klaviyo offers comprehensive engagement reports that provide insights into different lists and segments. During our evaluation, we were able to filter engagement by email client, allowing us to optimize our content for specific platforms.

For one of the businesses we work with, a tech startup, this feature proved invaluable. By analyzing engagement reports, they identified that a significant portion of their audience preferred mobile access. This led to a strategic shift in content formatting, resulting in higher engagement rates and ultimately, a more successful campaign.

Klaviyo's AI Assistant

Klaviyo's AI Assistant adds an extra layer of intelligence to your email marketing endeavors. We put it to the test by generating subject lines based on email type. This proved to be a time-saving gem, as it consistently produced compelling subject lines that resonated with our target audience.

One particular campaign for a lifestyle brand we work with saw a noticeable increase in open rates, thanks to the AI-generated subject lines. This demonstrated how Klaviyo's AI capabilities can play a pivotal role in optimizing your email campaigns for maximum impact.

Pros and Cons of Klaviyo

Klaviyo is a powerhouse when it comes to e-commerce email marketing, offering a suite of features designed to propel businesses to new heights. However, like any tool, it comes with its strengths and areas for improvement. Our in-depth exploration uncovered the following pros and cons of Klaviyo:


Advanced yet User-Friendly Tool

Klaviyo strikes an impressive balance between offering powerful, advanced features and maintaining user-friendliness. This is a rare fusion in the world of email service providers, making Klaviyo stand out. During our testing, we were able to navigate through its features seamlessly, even for more complex tasks like automation flows.

Advanced Sign-Up Form Builder

Klaviyo's form builder is a standout feature. With a plethora of design and style options, we found it to be one of the most versatile among the email service providers we've assessed. The ability to add custom fields and configure targeting and behavioral settings provided a level of customization that was particularly beneficial for e-commerce businesses.

List Creation and Segmentation

Klaviyo offers multiple avenues for list creation and segmentation. With seven segment options and advanced conditions, the possibilities for creating specific lists are nearly endless. Our team even extended the use of Klaviyo's segmentation tool outside of the platform, integrating it seamlessly with other systems. This level of flexibility was invaluable for tailoring campaigns to specific audience segments.

Detailed Engagement Reporting

The platform's engagement reports offer a wealth of information. Being able to filter by different email clients allowed us to fine-tune our content for specific platforms, ultimately resulting in higher engagement rates. For one partner company in the tech industry, this feature played a pivotal role in optimizing their email content for maximum impact on their target audience.

Excellent Customer Support

Klaviyo's customer support, while not always lightning-fast, provided consistently helpful responses that addressed the queries effectively. The availability of phone support, chat support, and an extensive knowledge base contributed to a positive customer experience.



One of the most significant drawbacks of Klaviyo is its pricing structure. While the features it offers are exceptional, the cost can be a hurdle for businesses, especially those on a tight budget.

Limitation on Monthly Email Sends

Klaviyo's tiered pricing plans come with a cap on the maximum number of monthly orders. For businesses with high order volumes, this could potentially lead to a pause in review requests, impacting the effectiveness of their campaigns.

Additional Costs for Extra Emails

Exceeding the allotted number of emails on a plan incurs extra costs. While this can be expected to some extent, it's important for businesses to carefully consider their email volume and budget accordingly to avoid unexpected expenses.

Alternatives to Klaviyo

While Klaviyo stands out as a formidable player among its competitors, it's essential to explore alternative options that may better suit specific business needs. Our team has identified several noteworthy alternatives that offer unique strengths and advantages:

1. Mailmodo

Mailmodo is an emerging force in the email marketing space, specializing in interactive AMP emails. This platform distinguishes itself by allowing businesses to create engaging and interactive emails, which can be particularly effective in capturing user attention. What sets Mailmodo apart is its cost-effectiveness, making it an attractive option for businesses on a budget.

2. Sendinblue

Sendinblue presents a compelling alternative to Klaviyo, especially for businesses focused on cost-effectiveness.

Additionally, Sendinblue offers a free sales CRM, providing an integrated solution for businesses looking to manage both email marketing and customer relationships.

3. Mailchimp

Mailchimp is a widely recognized name in the email marketing sphere and offers a range of features that can rival Klaviyo. Its drag-and-drop template builder, e-commerce marketing capabilities, and extensive integration suite make it a robust alternative. Additionally, Mailchimp is often considered more budget-friendly compared to Klaviyo, making it an attractive option for smaller businesses.

4. MailerLite

For businesses seeking a cost-effective yet powerful email marketing solution, MailerLite is a compelling choice. Notably, MailerLite offers a much more generous free plan compared to Klaviyo, making it accessible for businesses with limited budgets. Moreover, MailerLite is lauded for its quick and reliable customer support, which can be a critical factor for businesses in need of timely assistance.
