Constant Contact to Klaviyo Migration, For Brands Outgrowing the Basics
Constant Contact does broadcast email well. For ecommerce, the limits show up at automation, segmentation, and reporting. We migrate Constant Contact accounts to Klaviyo in 2-3 weeks with proper ecommerce flow architecture from day one.
Why brands move from Constant Contact to Klaviyo.
Constant Contact has limited automation
Klaviyo gives you the full ecommerce flow library: welcome, abandoned cart, post-purchase, replenishment, win-back, browse abandonment. Constant Contact has basic autoresponders.
Segmentation depth gap
Constant Contact segments by basic list/contact properties. Klaviyo segments by behaviour, predictive properties, product events, in real-time.
Native ecommerce integration
Klaviyo connects natively to Shopify and other platforms. Constant Contact integrates but the data depth is shallower.
Reporting that actually shows revenue
Klaviyo reports per-flow revenue and revenue per recipient. Constant Contact reports opens and clicks.

Constant Contact migration FAQ
Q.01 I use Constant Contact for events too, can I keep that? +
— Answer
Constant Contact's event marketing tools are not in Klaviyo. If events are core to your strategy, you may keep Constant Contact for events alongside Klaviyo for ecommerce email.
Q.02 Will my Constant Contact list segments transfer? +
— Answer
Functionally yes. Lists become Klaviyo lists, contact properties become Klaviyo profile properties, segment logic is rebuilt with Klaviyo's more powerful segmentation engine.
Q.03 What happens to my Constant Contact templates? +
— Answer
Rebuilt in Klaviyo using your Constant Contact designs as reference. Most brands take the opportunity to update templates for mobile-first design at the same time.
