# Klaviyo alternative

## Unitpost vs Klaviyo

> An email and SMS marketing platform for online stores, with flows on store events, segments on tracked events, predictive analytics, and SMS, push and WhatsApp on the same profiles.

**Klaviyo free tier:** Up to 250 active profiles and 500 email sends a month

**Klaviyo pricing shape:** Email is priced by active profiles: everyone Klaviyo can email counts, customers who never subscribed included, and the plan moves up a tier as the list grows. SMS and MMS are bought as credit packs on top, with carrier fees included.

## What Klaviyo does well

- Flows that start on store events, such as a price drop or low inventory, as well as list joins, dates and any tracked event
- Segments on tracked events, such as orders, and on profile properties, plus predictive analytics on each profile
- Email, SMS, MMS, push and WhatsApp consent on one profile
- A free plan to start, and an agency partner program

## Choose Klaviyo if

- You run an online store and most of your revenue comes from abandoned-cart, browse and win-back flows
- You segment on what people did in your store, not on fields your app sets
- Your marketing team builds flows without engineering
- You want predictive analytics on each customer

## Choose Unitpost if

- Your app sends receipts, resets and alerts to the same people your campaigns reach
- You'd rather pay for what you send than for every profile that could receive marketing
- You want a REST API, SMTP and an MCP server on every plan, with SDKs for the languages you use
- You want SMS on the same contacts, API key and bill as email

## How do I migrate from Klaviyo?

The Migration Assistant reads Klaviyo with an API key it only reads with, and previews what it can import before writing anything. Imports: contacts, unsubscribes and consent, suppressions (bounces and blocks), sms numbers and consent, lists. Partly imports: segments, templates, sending domains. Rebuild: topics, webhooks, api keys. Stays behind: flows, send history, analytics and forms.

## FAQ

### Is Unitpost a Klaviyo alternative?

For a SaaS or app that sends product email and campaigns to the same people, yes: one API and contact list, priced by sends, with SMS on paid plans. For an online store that runs on Klaviyo's store flows, purchase segments and predictive analytics, Klaviyo is the better tool, and Unitpost has no store integrations.

### Can I import my Klaviyo profiles into Unitpost?

Yes, with a Klaviyo Read-Only private key. The Migration Assistant brings profiles with their email consent and dated SMS consent, custom properties, lists and segments (as today's members), bounces and manual suppressions, and templates and recent campaigns with Klaviyo tags converted. Profiles with no email address, flows and webhooks stay at Klaviyo.

### Do I pay for customers who never subscribed?

Not here. Klaviyo counts every profile it can email, checkout-only customers included. Unitpost prices by what you send, and the importer brings never-subscribed profiles over unsubscribed from marketing, so transactional email still reaches them and campaigns skip them.
