Klaviyo is the best ecommerce email platform on the market — deep Shopify integration, predictive analytics, and SMS in one place. If you're a high-volume store that lives and dies by cart-event flows and CLV models, it earns its keep. Most senders, though, pay Klaviyo's per-contact tax for enterprise features they never touch.

SES Mailbox is a Klaviyo alternative for the next 99% of senders — campaigns, automations, segments, and analytics on Amazon SES for a flat $9.99/mo plus $0.10 per 1,000 emails. Below is the honest comparison — including the ecommerce features Klaviyo does that we don't.

When to stay on Klaviyo

We're being honest. Klaviyo is the best product in its category. Stay on it if you genuinely need:

Predictive analytics

CLV prediction, churn risk, next-order date. We don't ship these — most stores under $5M GMV don't use them anyway.

SMS bundled in

Klaviyo's SMS product is genuinely good. We focus on email — pair with Twilio or Postscript if you need SMS.

You’re at $200M+ GMV

If Klaviyo's $30k/year list is rounding error vs. revenue, stay. We exist for the next 99% of senders.

Klaviyo switching FAQ

The questions stores ask before moving.

How much does Klaviyo cost in 2026?

Klaviyo prices per contact — roughly $720/mo for email-only at 50,000 contacts, more with SMS. SES Mailbox is $9.99/mo flat plus AWS sending — about $15/mo total at that size.

Is SES Mailbox a good Klaviyo alternative for Shopify stores?

For campaigns and basic flows, yes — and the savings are large. But Klaviyo's real-time Shopify integration, predictive analytics, and cart-event flows aren't something we replicate. If those drive your revenue, Klaviyo may still earn its price; if you mostly send newsletters and promos, we win on cost.

Can I migrate my Klaviyo lists?

Yes. Export your profiles and segments as a CSV and import into SES Mailbox with field mapping — segments become targetable lists. Most stores migrate their email setup in under an hour.

What does Klaviyo do that SES Mailbox doesn't?

Predictive analytics (CLV, churn, next-order date), deep ecommerce event integrations, built-in SMS, and A/B testing. We focus on cheap, deliverable email on AWS SES.

Does SES Mailbox have a free plan?

Yes — free forever, no credit card: unlimited subscribers and one campaign per month. Klaviyo's free plan caps you at 250 contacts.
