What Users Say

Real reviews from Klaviyo and Constant Contact users

Klaviyo Reviews

Klaviyo transformed our Shopify store's email marketing. Revenue attribution shows our automations generate $30k/month. Constant Contact couldn't provide anything close to this.

Nicole P.2025-10-14
Capterra

Excellent for e-commerce but we're a local service business. Klaviyo's features are designed for online stores. Constant Contact's event tools and phone support fit us better.

Constant Contact Reviews

Constant Contact handles our nonprofit's email and event marketing perfectly. We run quarterly fundraising events with built-in registration. Phone support saves us hours.

Reliable for basic email but the e-commerce features are weak. We tried to use it for our online store and switched to Klaviyo within a month. Different tools for different businesses.

Note: Sequenzy Is for SaaS Companies

Different Focus

Sequenzy is built for SaaS companies. If you run e-commerce, use Klaviyo. If you are a traditional small business or nonprofit, Constant Contact works. If you build software, Sequenzy is designed for you.

Stripe Integration

For SaaS founders, Sequenzy's native Stripe integration enables subscription-aware automation. This is more valuable than e-commerce features or event management for software businesses.

Modern Platform

Unlike Constant Contact's traditional approach, Sequenzy is a modern platform built for software companies with API-first design and developer-friendly features.

Overview

Klaviyo and Constant Contact represent different eras and approaches to email marketing. Klaviyo is a modern, data-driven platform built for e-commerce. Constant Contact has been around since 1995, serving traditional small businesses and nonprofits with straightforward email needs. See our detailed Klaviyo comparison and Constant Contact comparison.

Modern E-commerce vs Traditional Email

Klaviyo was built for the e-commerce era. Deep Shopify integration, predictive analytics, product recommendations, and SMS marketing are core features. Every aspect is designed to help online stores generate more revenue.

Constant Contact is a traditional email marketing platform. It serves small businesses, churches, nonprofits, and local organizations that need to send newsletters, manage events, and stay in touch with their communities. Email marketing without the complexity.

E-commerce Capabilities

For e-commerce, Klaviyo is vastly superior. Its Shopify integration syncs all customer data in real-time. Predictive analytics identify who will buy and when. Product recommendations personalize every email automatically.

Constant Contact can connect to Shopify but the integration is basic. You can send abandoned cart emails, but you will not get the sophisticated features that drive serious e-commerce revenue.

Traditional Business Features

Constant Contact includes features Klaviyo does not: event management with RSVP tracking, built-in surveys, social media posting, and a logo maker. These tools serve traditional small businesses and nonprofits well.

Constant Contact also offers nonprofit discounts up to 30% off, recognizing that many of its customers are churches, community organizations, and charitable groups.

Ease of Use

Constant Contact is simpler. Its interface is traditional and straightforward. Users without marketing expertise can create and send emails quickly. The learning curve is gentle.

Klaviyo is more powerful but more complex. E-commerce businesses benefit from investing time to learn the platform, but that investment is real.

Pricing Comparison

At 10,000 subscribers, Constant Contact costs $80/month. Klaviyo costs $150/month. For businesses that do not need e-commerce features, Constant Contact's lower price is attractive.

The Verdict

Choose Klaviyo if you run an e-commerce store and want the best tools available. Its specialized features will drive more revenue than a general email platform.

Choose Constant Contact if you are a traditional small business, nonprofit, or organization with straightforward email and event management needs.

For SaaS Companies

Neither is ideal for SaaS. Klaviyo is e-commerce focused. Constant Contact is traditional business focused. Sequenzy is built specifically for SaaS with Stripe integration, subscription-aware automation, and modern features designed for software businesses.

Fundamentally Different Audiences

Klaviyo serves online stores that sell products through Shopify, WooCommerce, and similar platforms. Constant Contact serves local businesses, nonprofits, and organizations that communicate through events and email. These audiences have almost no overlap. Comparing them directly is misleading — they are not competing for the same customers. An online retailer would never consider Constant Contact. A local nonprofit would never consider Klaviyo. Choose based on your business type, not feature comparisons.

The Event Marketing Factor

Constant Contact's event marketing capabilities — registration pages, ticketing, attendee management, and automated follow-ups — serve organizations that run events as a core business activity. Klaviyo has no event features because online stores rarely host events. For organizations where events drive engagement and revenue, Constant Contact's integrated event tools provide unique value. For online stores where purchase behavior drives strategy, Klaviyo's e-commerce automation is irreplaceable.

Phone Support as Business Requirement

Constant Contact offers phone support that small business owners and nonprofit managers rely on for immediate help. Klaviyo provides chat and email support typical of modern SaaS tools. For organizations where the person managing email marketing is not technically sophisticated, phone support provides a safety net that reduces risk and anxiety. For e-commerce teams with technical capabilities, Klaviyo's self-service approach is sufficient.
