Mailchimp vs. Klaviyo

Before you start to migrate Mailchimp to Klaviyo, we must make sure that your new email marketing tool has everything you need. If you are thinking of switching from Mailchimp to Klaviyo, you might want to check out the differences between the tools and see if Klaviyo is the right choice. 

A growth marketing tool that helps you connect with customers through email, sms or in-app notifications will help you immensely in increasing revenue and converting new customers. Using the right email marketing tool means reaching the right audience based on the way that your visitors interact with your content. If you want to reach out to your visitors and potential customers to increase revenue, do not underestimate the power of a well-crafted email. 


Available Features: Klaviyo surpasses Mailchimp with its automation features, customization options and analytics. While Mailchimp also offers similar features, they are not available for in-depth use and can remain surface-level for marketing professionals that prefer discovering the roots of a possible problem.

Ease of Use: Since it does not offer a lot of in-depth features with a potential for complications, Mailchimp is considerably easier to use than Klaviyo. There is not much of a learning curve to get through with Mailchimp. You can dive in right away. 

Digital marketing: Mailchimp’s redeeming quality is that it offers integration with marketing channels other than email, like landing pages or ads. However, Mailchimp does not have SMS service. 


Data Integration: One of the considerable advantages that Klaviyo offers is its data integration features. Klaviyo will collect data from your marketing channels to inform your email templates and help you craft different alternatives based on how your customers and visitors interact with your content. 

Personalization: Through its data integration features, Klaviyo allows for personalization of your email templates and helps you catch the attention of your potential customers based on their own personalized data. This means that you can refer to your potential customers’ past interaction with your website in your email which will help make your visitors feel cared for upon receiving your email. It will also help you better target your email marketing campaigns. 

Learning Curve: While the platform is fairly easy to use in the long run, learning the ins and outs of the features may take some time. Users have pointed out that the initial learning curve can be challenging which may lead you to waste a bit of time trying to figure out how to progress on the tool. This may be a problem if you need an immediate solution and don’t have the time to go through a challenging learning process. 

Another problem that users have pointed out is that the dashboards on Klaviyo can be difficult to understand if you are working with a bigger chunk of data across multiple platforms. The data visualization can be messy.

Some users have admitted to needing an external platform to visualize the data to render their reports more easy to understand. Externalizing your reports may become a time consuming task later on. heybooster simplifies this process for you through prioritized automated reporting and gives you easy-to-understand reports with clear and actionable insights to improve your eCommerce strategy. 

Pricing: Pricing is one of the biggest complaints that users of Klaviyo across the world have voiced. Unfortunately, Klaviyo’s pricing can be overwhelming for small to medium size eCommerce companies. Another problem is that because there is no longer an “unlimited contacts” option in any of the price tiers, the more contacts you add on to your list, the more you have to pay. This can be a problem for rapidly growing companies with an extending audience. 

How to migrate Mailchimp to Klaviyo

  1. Disconnect the integration between Mailchimp and your eCommerce platform. 
  2. Integrate Mailchimp to Klaviyo. To do this, you will need to create an API key on Mailchimp. This is fairly easy. All you need to do is to go to your Account on Mailchimp and find the Extras option. Then, click on Create a Key and copy. Then you can head to Klaviyo Integrations and click on Mailchimp. You can paste your API key to finish the process. 
  3. You can pick the type of data you want to bring from Mailchimp through the Advanced Integration option.  
  4. Import the Mailchimp tags to Klaviyo. It is unfortunately impossible to automate this process as Klaviyo does not allow you to import your Mailchimp tags. Export your tags and then add them on Klaviyo separately. Your tags will appear as custom properties. 
  5. Re-do your Mailchimp templates on Klaviyo. Now, you can start creating new templates on Klaviyo. If you want, you can also export your pre-existing templates on Mailchimp as HTML and import to Klaviyo.
