Which is better for e-commerce?
Klaviyo
Klaviyo was built for online stores. It syncs product catalogs, purchase history, and browsing behavior from Shopify, WooCommerce, and BigCommerce in real time. You can segment by purchase frequency, average order value, predicted lifetime value, and churn risk. The 80+ pre-built flows cover abandoned carts, post-purchase follow-ups, win-back campaigns, browse abandonment, back-in-stock alerts, and price drop notifications. Revenue attribution is automatic.
Constant Contact
Constant Contact integrates with Shopify and WooCommerce at a basic level. You can add product blocks to emails and set up simple purchase-triggered automations. There's no product catalog sync, no browsing data, no predictive analytics, and no browse abandonment tracking. For stores that only need occasional product emails and abandoned cart reminders, it works. For anything more, it falls short.
Winner: Klaviyo. Klaviyo was built for online stores.
Which has better automation?
Klaviyo
Klaviyo's Flows system supports complex multi-step sequences with conditional branches, time delays, and A/B splits. The 80+ pre-built flows are optimized for e-commerce and can be customized or built from scratch. Triggers include purchases, cart abandonment, browsing activity, email engagement, and custom events. Automation is available on all plans including free.
Constant Contact
Constant Contact's automation is limited. The Standard plan includes 3 pre-built workflows (welcome, birthday, anniversary) with no custom automation builder. Premium ($80/mo) adds more templates but still lacks a visual flow builder with conditional logic. If you need multi-step sequences that branch based on behavior, Constant Contact can't deliver.
Winner: Klaviyo. Klaviyo's Flows system supports complex multi-step sequences with conditional branches, time delays, and A/B splits.
Which is easier to use?
Klaviyo
Klaviyo has a learning curve, particularly around the segment builder which uses technical terminology. Setting up flows and building segments takes time to master. The interface is powerful but assumes some familiarity with email marketing concepts like behavioral triggers and conditional logic. Most users need a few sessions to get comfortable.
Constant Contact
Constant Contact is one of the simplest email platforms available. You can create and send a campaign in under 20 minutes. The editor is straightforward, templates are easy to customize, and there's phone support on all plans. For non-technical users who want to send newsletters without a learning curve, Constant Contact is hard to beat.
Winner: Constant Contact. Constant Contact is one of the simplest email platforms available.
Which is cheaper?
Klaviyo
Klaviyo has a free plan covering 250 active profiles and 500 emails/mo. The Email plan starts at $20/mo for 251-500 profiles. Email + SMS starts at $35/mo. At 10,000 profiles, Email costs $150/mo. Klaviyo only charges for active profiles (contacts emailed in the past 365 days), so inactive contacts don't inflate your bill.
Constant Contact
Constant Contact has no free plan but offers a 60-day free trial (no credit card required). Lite starts at $12/mo (annual) for 500 contacts. Standard is $35/mo for 500 contacts. Premium is $80/mo. At 10,000 contacts, Standard costs about $120/mo. All contacts count toward your billing limit.

Constant Contact
Constant Contact has one of the highest deliverability rates in the industry at 88% in independent tests. It has built a reputation over 25+ years for reliable inbox placement. For businesses where deliverability is the top priority, Constant Contact has the strongest track record.

Which has better SMS marketing?
Klaviyo
Klaviyo bundles SMS into the Email + SMS plan for $15/mo more than Email-only. SMS is a first-class channel: you can build flows that combine email and SMS, segment by SMS engagement, and track SMS revenue attribution. For e-commerce stores, SMS drives urgency for flash sales, shipping updates, and abandoned cart reminders.
Constant Contact
Constant Contact offers SMS as a paid add-on, and it's limited to US numbers only. The SMS features are basic compared to Klaviyo's integrated approach. Most Constant Contact users rely on email as their primary (and often only) marketing channel.
Winner: Klaviyo. Klaviyo bundles SMS into the Email + SMS plan for $15/mo more than Email-only.
