Klaviyo Pros 

There are several reasons why Klaviyo could be a good fit for your business. We mention a few of their top features based on the most critical aspects of email marketing.

1. Email Deliverability

Klaviyo is generally known for its high deliverability rates, although there is no relevant data to back it up. Several of their tools help track email deliverability, including campaign trend reports and campaign performance reports. The score tab shows you the deliverability health of emails and SMS campaigns. However, you must send at least 1000 emails in the last 30 days for the software to calculate the score. 

The action center features key steps clients can take to improve their email deliverability performance. Additionally, deliverability alerts show which email metric is experiencing poor performance with a link to a troubleshooting guide. 

2. E-commerce Features 

One of the most significant advantages of Klaviyo is how it’s centered around data and customer behavior, enabling e-commerce stores to better connect with their customers. Predictive data science is embedded throughout the platform, enabling smarter decisions for your email campaigns. 

The built-in predictive analytics uses historical data to forecast future customer behavior so that you can use better segmentation strategies.

Behavior forecasting predicts the following:

  • Next order date, 
  • Lifetime Value,
  • Churn risk,
  • Spending potential,
  • Automated A/B testing, 
  • Predicted demographics.

3. Email Segmentation

Clients can group contacts into precise audiences that update in real-time, allowing you to target messaging based on the latest customer shopping behavior. Klaviyo allows you to set as many rules for the customer journeys and use it with 200+ native integrations.

Their code-free segment builder permits you to send targeted messages based on customer lifetime value, on top of all other data you have collected. You can use the customer segments for omnichannel marketing, such as SMS and social media.

4. Analytical Abilities

Klaviyo’s dashboards help you visualize all KPIs in a single place. However, their reporting comes with customizable dashboards for easier data evaluation. The software integrates data from tech stacks and offers a one-view report.

We also found that the platform issues pre-built report templates that help you uncover trends and optimize your ROI. You can also view the benchmarks on the sidebar — the ESP claims they’re the only e-commerce marketing platform with built-in, personalized benchmarks. 

5. Built for Shopify and Other E-commerce Platforms

Unlike other marketing tools that require third-party integrations, Klaviyo directly integrates with Shopify. With Shopify’s $100M investment, the ESP has announced a strategic partnership between them.

Besides Shopify, the platform has over 200 pre-built integrations to Shipstation, Gorgias, and Recharge. It also connects to several customer support tools, SMS tools, loyalty programs, user-generated content, subscription tools, and virtually any other marketing tool you use.

6. Scalability 

Klaviyo is one of the few platforms that can scale with your business — it offers advanced features as you build your business. You can create unique experiences for each customer and get more attention with one-time sends. 

The software integrates with all of your favorite marketing tools and moves processes faster with artificial intelligence. 

7. Automated Flows and Triggers

Klaviyo has an in-built automation platform that lets you set up the following:

  • Welcome series
  • Browse abandonment
  • Cross-sell to inactive customers
  • Back-in stock alerts
  • Shipping updates

All of these can be customized according to the buyer’s journey for maximum impact.

8. A/B Testing

The platform offers an in-built A/B testing tool that lets marketers easily test their campaigns. You can A/B test subject lines, discounts, CTAs and any other element inside the campaign.

You don’t need a degree in mathematics to understand analytics; they are particularly user-friendly, as the users claim

Overall, a Good Growth Tool

Clients love the ESP for its ability to help businesses uncover growth opportunities. The high volume of data and insights it offers makes it easier for e-commerce brands to thoroughly analyze email metrics and customer journeys.

Besides email, you can use SMS and build several sign-up forms for lead generation. For example, you could build a seasonal campaign with email, SMS, and push notifications. Or create rules for each marketing channel and when it should be sent.


Klaviyo Cons 

The platform may be more expensive than other marketing platforms offering similar features. Here are other disadvantages reported by its clients.

1. Learning Curve

Although it provides helpful guides, you’re mostly on your own after the onboarding process. You might need external support to set up segmentation or email flows. 

2. SMS Performance

The onboarding process for SMS is shorter than for emails; however, you must meet certain price thresholds to get to the onboarding stage. Klaviyo offers SMS credits and the price per credit varies on the quantity you buy. If you plan to use SMS alongside emails, it might cost more since you’ll be paying the SMS carrier charges as well.

3. Weaker E-commerce Integrations (Other than Shopify)

Brands using Woocommerce or Magento find it challenging to integrate with Klaviyo. With the strategic investment from Shopify, the platform has announced its major focus on the platform. If you work with any other marketing tool other than Shopify, it’s better to consider Klaviyo alternatives.

4. Lack of Dedicated IPS

The ESP onboarded many accounts during the pandemic but failed to provide dedicated IPs to these companies, resulting in lower email deliverability rates for them.

5. Time-Consuming Reporting 

Reporting is more time consuming than in other email platforms. It often involves downloading large amounts of data from the platform and manually filtering them in sheets to answer specific questions.

6. Customer Support

Users found the support team to be slow and inconsistent at times. They also report that its chat function doesn’t always work.

Overall, Quite Tedious and Demanding

Klaviyo can have a steep learning curve, especially for non-technical users. Ensuring every detail in triggers or campaigns is updated can consume time and leave room for errors. Clients feel that certain features can be simplified to cut down time and enrich the learning process for beginners.

Customers’ biggest concern is the slow customer support and technical issues with chat options.
