As of today, email marketing remains fundamental for any digital strategy, especially in e-commerce, as these platforms offer a wide range of features including automation, integration with online stores, and management of campaigns on social networks.
At Open Rate Club we have tested both solutions, spoken with experts and companies that have implemented one or the other in their operations and can offer a clear vision. The choice of the right platform can directly impact conversion and campaign success. A clear vision that, based on the fact that choosing one tool or another will depend on our specific needs, will help us decide between Mailchimp and Klaviyo.
Which option to choose?
Key Features: What Makes Each Platform Special?
Both platforms aim in the same direction with their offerings and functionalities, but they specialize in certain areas or better cover some requirements than others. In this analysis, we will review the main features and the range of tools of both services to understand their advantages and differences. Additionally, both platforms allow managing campaigns through multiple channels, such as social media, email, and other digital media, enhancing brand presence and customer interaction.
Mailchimp
Mailchimp stands out especially for its interface. It is one of the easiest platforms to use, providing an intuitive and friendly interface for beginners, allowing efficient campaign management.
Mailchimp offers tools to create campaigns and send emails efficiently, facilitating the customization and automation of mailings to improve interaction and conversions. This translates into a higher number of sales.
With Mailchimp free, we can use lists of up to 500 contacts, making it ideal for projects in their early stages. What exactly does it offer us?
- Email templates that we can easily customize with a drag and drop editor, allowing us to adapt designs to our requirements without advanced technical knowledge.
- Mailchimp’s segmentation list, with filters to group subscribers based on demographic data or open activity, for example. This way it is possible to send exactly to those we want.
- Really simple automations such as the welcome series or birthday reminder that give a personal touch to our relationship with subscribers.
Especially noteworthy is Mailchimp’s API, which gives us integrations with Zapier, Shopify, and WooCommerce, which are basic for many projects—. Thanks to this API, we can connect purchase data and synchronize our customers with the mailing lists we use.
Additionally, the Mailchimp integration with Facebook facilitates the creation of custom audiences directly from the platform’s data. Mailchimp stands out for its competitive advantages in design and automation compared to other platforms.
Klaviyo
Klaviyo is designed and created for the growth of online stores and to maximize purchase recurrence. This software offers a wide range of advanced tools for e-commerce, facilitating automation and personalization of campaigns.
Its dashboard provides immediate access to key metrics for the success of a project of this kind, such as CLTV and customer cohorts. With excellent design and great clarity in the data, the tool stands out in several areas:
- Predictive and automatic segmentation based on purchase actions and navigation patterns. Klaviyo allows us to easily create groups according to customer lifetime value or the date of their last purchase.
- Ability to create automated workflows that include sending emails as well as text messages within the same scenario. With Klaviyo SMS we have the flexibility of multichannel communications without the need for external solutions. Additionally, it is possible to customize customer journeys so that each flow adapts to their behavior.
- Custom events that can be defined via the Klaviyo API and allow us to capture actions such as adding a product to the cart or generating a product detail view.
The native Klaviyo integration with Shopify allows us to have automatic mapping of purchase data, abandoned carts, and product stock. All this is facilitated by the fact that Klaviyo offers hundreds of email templates to deliver the right message at the right time.
These features optimize marketing work and help achieve better results in campaign and sales management.
Why look for alternatives
Analyzing limitations is a fundamental part of the platform selection process. Just as the strengths of each tool convince us to use them, the limitations invite us to look for alternatives. What could Mailchimp and Klaviyo improve?
Limitations of Mailchimp
As our contact list grows, Mailchimp’s prices also increase. In addition, although the service has its own A/B testing and push notification service, its automation functions focus on much more basic flows than Klaviyo.
On the other hand, the system we call Mailchimp transactional emails (or Mandrill) requires separate activation and extra configuration, which in some implementations adds more complexity to the onboarding.
Challenges of Klaviyo
While its automations are outstanding, its integrated transactional email system has a somewhat steep learning curve to configure certain flows and custom events.
Also consider at this point that Klaviyo’s customer support, although it offers quick responses, may require a subscription to higher plans for priority attention.
