Featured Testimonials

  • "Taking the leap from Mailchimp to Klaviyo has helped supercharge our growth. Automated flows and segmenting help us deliver personalized and exciting content that our newsletter members really enjoy. This relevancy makes every point of contact more meaningful and useful for our current and future customers."

  • "We made the switch from Mailchimp because we were unhappy with the limited customization on automated email flows. We knew money was being left on the table. Moving to Klaviyo was extremely easy, and we had a customer support member walk us through the whole process. Integrating with Shopify took less than 5 minutes, and we had our whole account up and running (email flows and all) in a matter of 1-2 days."

  • “Personalizing text messages in Klaviyo is insanely simple. You see the info you want to add to the message, click on it to copy the data, then paste and it’s done. No need to ask for help, read some complex doc, or type and pray.”
