Klaviyo is the better choice for online stores, because its flows and segments run on order, cart and browsing data that Constant Contact’s broadcast-first tools don’t use the same way. Constant Contact is the better choice for local businesses, nonprofits and event-led marketers that mainly send newsletters and want event tools, social posting and live phone support in the same account.
Constant Contact has a long track record in small-business email, and the product does what it’s built for well. The question for an ecommerce brand is whether what it does is what you need.
A note on where we stand: we’re an official Klaviyo partner and we run Constant Contact to Klaviyo migrations, so we have a stake. That’s why the cases where Constant Contact wins are spelled out below, and why every price comes from the vendors’ own pricing pages, checked on 10 October 2026.

Klaviyo vs Constant Contact Pricing (October 2026)
Constant Contact prices on contacts and plan; Klaviyo prices on active profiles. Monthly prices in USD, from each vendor’s pricing page on 10 October 2026:
| Contacts / active profiles | Constant Contact Lite (billed annually) | Klaviyo (email) |
|---|---|---|
| 1,000 | $25.50 | $30 |
| 5,000 | $68 | $100 |
| 10,000 | $102 | $150 |
| 25,000 | $238 | $400 |
| 50,000 | $365.50 | $720 |
Constant Contact Lite figures are its published fee schedule, billed annually; monthly billing costs more (prepaying 12 months saves up to 15%). Above 50,000 contacts Constant Contact quotes through sales.
The table flatters Constant Contact, because Lite is a basic plan: one automation template, one custom segment and basic reporting. Standard starts at $35 a month ($29.75 billed annually) and Premium at $80 ($68 billed annually) for up to 500 contacts, and both rise with your list. Premium is the plan with ecommerce automation templates, custom automations, unlimited segments and revenue reporting, and at 500 contacts it already costs four times Klaviyo’s $20. Our Constant Contact pricing guide breaks down every plan.
Why is Klaviyo so expensive?
Against Constant Contact Lite, it costs more at every size: $150 against $102 at 10,000. But Lite and Klaviyo aren’t the same product. Klaviyo bills on active profiles, everyone you can email, and each profile carries orders, browsing and predictions that its flows use. Since February 2025 your plan has to cover that full count, so suppressing people who never engage is the quickest way to cut the bill. Every tier is in our Klaviyo pricing guide.
Constant Contact Is Built for Broadcast; Klaviyo Is Built for Behaviour
Constant Contact treats email as a broadcast channel: build a list, design an email, send it. Its automations sit on top of that foundation.
Klaviyo treats every contact as a profile with full event history (purchases, page views, cart events, predicted properties), and email and SMS are ways of acting on that profile.
For an online store the difference matters, because most email revenue comes from behavioural triggers, not broadcasts: a welcome series after sign-up, abandoned cart after a checkout is dropped, post-purchase timed to the order, replenishment timed to consumption, browse abandonment after product views. Those run best on a platform built around events.
Where Constant Contact Wins
Simplicity and support. The interface is straightforward, and every plan includes live phone and chat support. For a small business sending a few newsletters a month, that matters.
Events. Every plan can host events, sell products and take payments. Klaviyo has no equivalent.
Social and ads in the same account. Scheduled posts to Facebook, Instagram and LinkedIn, and an ads manager, sit alongside email.
Local business, nonprofit and B2B-light fit. Restaurants, professional services and community organisations whose marketing is “send updates to my list” are at home here.
Lower entry price for basic email, with a 30-day money-back guarantee.
Where Klaviyo Wins for Ecommerce
Native store integration. Klaviyo connects to Shopify, BigCommerce, WooCommerce and Magento with orders, catalogue, customer data and cart events flowing onto each profile in real time.
Behavioural automation. A flow library built around ecommerce lifecycles (welcome, abandoned cart, browse abandonment, post-purchase, replenishment, win-back, back in stock) with conditional splits on any event or property, on every plan.
Segmentation depth. Real-time segments on behaviour, purchase history and predicted properties, combined however you need, with no segment limit.
Predictive analytics. Predicted CLV, churn risk and next order date, native to Klaviyo.
SMS beyond the US. Klaviyo sells SMS in many countries on the same profile as email; Constant Contact’s SMS is for US customers only.
Reporting that maps to revenue. Revenue per recipient, attributed orders, flow contribution and segment-level performance, on every plan.
Pros and Cons
Klaviyo

- Full ecommerce flow library and unlimited segments on every plan
- Predictive analytics and revenue reporting
- Email and SMS on one profile

Constant Contact
Pros
- Live phone and chat support on every plan

- Low entry price for simple newsletters
Cons
- Automation and segments limited on Lite and Standard
- Ecommerce automation templates only on Premium
- SMS for US customers only

What are the weaknesses of Klaviyo?
Against Constant Contact, Klaviyo has no event tools or social scheduling, its support is email and chat rather than phone, and it costs more than Lite at every list size. Across the board, cost rises with every active profile, SMS is billed on top of email, and it’s built for B2C ecommerce, so it does little for a nonprofit or local service business. Our Klaviyo review goes through each one.
When to Stay on Constant Contact
- You’re not an online store. Restaurants, professional services, nonprofits and B2B-light businesses fit its broadcast-first design.
- Your list is small and your needs are simple. Under about 1,000 subscribers, no automation, weekly newsletters.
- Events are your main marketing channel. Its event tools do things Klaviyo can’t.
When to Migrate to Klaviyo
Migrate when:
- You’re past about 1,000 active subscribers and growing
- You want abandoned cart, post-purchase, replenishment or other behavioural flows
- You suspect email should be a bigger share of revenue than it is
- You’re spending on paid acquisition and want email retention to compound it
- Constant Contact’s reports don’t show what email contributes to revenue
The move is straightforward: two to three weeks for most accounts, covering templates, automations, contact import and authentication. Our Constant Contact to Klaviyo migration page has the detail.
Who is Klaviyo’s biggest competitor?
Not usually Constant Contact. For small and mid-size online stores, Klaviyo’s main rivals are Mailchimp and Omnisend; for SMS, Attentive and Postscript; at enterprise scale, Braze and Iterable. Our Klaviyo alternatives guide compares them by use case.
Practical Recommendation
Online stores where email is meant to drive repeat revenue: Klaviyo. Its store data, flows and revenue reporting fill the gaps a broadcast-first platform wasn’t built to fill.
Non-ecommerce small businesses and event-led marketers: stay on Constant Contact. It’s a good fit for what it was designed for.
The switch point usually comes when a store starts treating email as a revenue channel rather than a newsletter. If you’re there, book a free audit. We’ll review your account and tell you honestly whether the move is worth it.

/ Frequently Asked Questions
Q.01 Is Klaviyo better than Constant Contact? +
/ Answer
For an online store, yes. Klaviyo's flows and segments run on order, cart and browsing data from your store, and it reports email and SMS revenue per recipient. Constant Contact is better for local businesses, nonprofits and event-led marketers who mainly send newsletters, because it bundles event tools, social posting and live phone support into every plan.
Q.02 Is Constant Contact cheaper than Klaviyo? +
/ Answer
On list price, yes. As of October 2026, Constant Contact Lite billed annually is $25.50 a month at 1,000 contacts, $102 at 10,000 and $365.50 at 50,000, against Klaviyo's $30, $150 and $720. But Lite includes one automation template and one custom segment. Ecommerce automation templates, custom automations and unlimited segments need Premium, which starts at $80 a month for 500 contacts on monthly billing.
Q.03 Is there anything better than Constant Contact? +
/ Answer
It depends on the business. For an online store that wants revenue from abandoned cart, post-purchase and win-back flows, Klaviyo is the stronger platform. For newsletters on a tight budget, MailerLite and Mailchimp cost less. For events, local marketing and live phone support in one account, Constant Contact is hard to beat.
Q.04 Is Constant Contact outdated? +
/ Answer
No. It still ships new features, such as an AI campaign builder on Standard, and includes live phone and chat support on every plan. It is built around broadcasts to a list, which suits newsletters, nonprofits and events. For an online store's behavioural flows it's the wrong shape rather than outdated.
Q.05 Who is Klaviyo's biggest competitor? +
/ Answer
For small and mid-size ecommerce brands, Mailchimp and Omnisend; Constant Contact competes for small businesses but rarely for stores with real order volume. For SMS, Klaviyo's main rivals are Attentive and Postscript, and at enterprise scale Braze and Iterable.
