Klaviyo and Constant Contact are aimed at fundamentally different buyers. Klaviyo is a sophisticated e-commerce email and SMS platform built around customer data from online stores. Constant Contact is a simple, beginner-friendly tool that has historically served local businesses, nonprofits, and anyone who just needs to send a newsletter.
There is very little overlap between them. If you run an online store, Klaviyo. If you do not and want something simple, Constant Contact.

Different tools for different businesses
These two tools serve different markets so clearly that a direct comparison is almost academic. Klaviyo's value is in e-commerce intelligence: Shopify data, purchase-based segmentation, revenue attribution. Constant Contact's value is in simplicity, event management, and a long track record with small local businesses.
If you are trying to choose between them, the deciding factor is almost certainly whether you run an online store.
Pricing
Constant Contact is more affordable for businesses that do not need e-commerce features. Klaviyo's pricing scales with contacts and becomes expensive quickly. For a 5,000-subscriber list, Constant Contact runs around $55/mo while Klaviyo can reach $100/mo or more.
Klaviyo's pricing is worth it if you are driving meaningful e-commerce revenue through email. It is not worth it otherwise.
Automation
Klaviyo's automation is significantly more advanced, with deep behavioral triggers based on purchase history, browse abandonment, and predictive analytics. Constant Contact's automation is basic: welcome series, simple drip sequences.
For non-e-commerce automation needs, even Constant Contact's basic builder may be sufficient.
Choose Klaviyo if...
- You run an e-commerce store and want deep Shopify or WooCommerce integration
- Revenue attribution and purchase-based segmentation are important
- You want SMS alongside email in one platform
Choose Constant Contact if...
- You run events and want registration management built in
- You are a nonprofit, local business, or association
- You want a simple tool with strong customer support
- E-commerce features are not relevant to your business
The bottom line
Klaviyo for e-commerce. Constant Contact for everyone else who values simplicity, events, and strong support at an accessible price.
