Klaviyo vs Constant Contact (2026)

Quick answer: Klaviyo and Constant Contact serve different users. Constant Contact is a simple, affordable email tool for small businesses and nonprofits (from ~$12/mo, no free plan) with basic automation. Klaviyo is a deep ecommerce platform with branching behavioral flows, predictive analytics, and stronger deliverability. For an online store that wants real automation, Klaviyo wins clearly; for a nonprofit or service business wanting simplicity, Constant Contact is enough.

Key takeaways

• Constant Contact = simple, cheap email for any small business; limited automation.
• Klaviyo = deep ecommerce automation with branching flows and predictive data.
• The ecommerce capability gap is large — Constant Contact has only a few prebuilt workflows.
• Choose on whether you’re running an ecommerce store or simple newsletters.

Quick verdict

If you run an ecommerce store and want automation that actually drives revenue, choose Klaviyo. If you’re a nonprofit, local service business, or organization that mostly sends newsletters and wants the simplest possible tool, Constant Contact does the job for less.

Pricing

Constant Contact starts around $12/month with no free plan. Klaviyo is free up to 250 contacts and then scales with active profiles. At a like-for-like size Constant Contact is often cheaper — but you’re paying for a simpler tool, so the comparison hinges on what you need rather than headline price. See our Klaviyo pricing guide for the full breakdown.

The ecommerce capability gap

This is the deciding factor. Constant Contact offers a handful of prebuilt automations and no visual branching builder — you can’t easily build conditional, behavior-driven journeys. Klaviyo offers 60+ ecommerce flows with conditional splits, real-time behavioral data, and predictive analytics. For abandoned cart, browse, and post-purchase flows that actually convert, Constant Contact simply isn’t built for it.

Automation

Klaviyo’s automation is the product; Constant Contact’s is a feature. If your strategy depends on triggered, segmented, branching flows — and for ecommerce it should — Klaviyo is in a different class. Constant Contact suits time-based drips and newsletters, not revenue-driving ecommerce journeys.

Deliverability

Both deliver competently, with Klaviyo typically edging ahead on inbox placement for engaged-segment sending. As always, authentication and list hygiene matter more than the platform — our deliverability guide applies to either.

Who should pick which?

• Choose Klaviyo if: you run an ecommerce store and want behavioral automation, segmentation, and predictive data that drive revenue.
• Choose Constant Contact if: you’re a nonprofit, association, or small service business that mainly sends newsletters and values simplicity and low cost over depth.

Frequently asked questions

Is Klaviyo better than Constant Contact?

For ecommerce, yes — Klaviyo’s branching behavioral flows, segmentation, and predictive analytics drive far more revenue. Constant Contact is better only if you want a simple, cheap newsletter tool for a non-ecommerce business.

Is Constant Contact cheaper than Klaviyo?

Often at a like-for-like contact count, since it starts around $12/month. But it’s a simpler tool with limited automation, so the lower price reflects fewer capabilities rather than better value for an ecommerce store.

Can Constant Contact do abandoned cart emails?

Its ecommerce automation is limited and it lacks a visual branching builder, so behavior-driven flows like abandoned cart are far weaker than Klaviyo’s purpose-built versions. For real cart recovery, Klaviyo is the better fit.
