What our research says

Klaviyo

The default marketing stack for Shopify-scale e-commerce because its data model is built around customer events rather than lists, so predictive fields and AI-built segments actually have something to work with. The free tier is a sandbox, the real cost climbs with active profiles, and once SMS, Composer usage and service modules are switched on the invoice has several meters, not one.

Pros

Pricing by active profiles with a real free tier (250 profiles, 500 sends) and no card
Predictive churn, lifetime value and next-order date per profile built in
Composer builds and audits flows and campaigns from natural-language prompts
Public REST API with maintained SDKs in Python, PHP, Ruby and more
Email, SMS/MMS, push and a helpdesk module share one customer profile

Cons

Costs step up with every active-profile band; the $20 entry price covers only 251–500 profiles
SMS, Composer usage and support packages are separate meters on top of the plan
The pricing page shows the entry bands and leaves larger bands to a calculator
The platform has widened into service and analytics, adding modules a small brand will not use

The AI CMO

The AI CMO's pitch is volume with governance—one approval queue reviewing output from specialists that would otherwise be separate hires or agencies—which fits larger operators managing many brands or campaigns at once. At $299 to start and scaling to $1,499/month before Enterprise, it's priced for teams already spending meaningfully on marketing execution, not a first tool for a small brand.

Pros

Single approval queue covers output across email, SMS, push, social ads and landing pages
Data connections include direct database and webhook options, not just app integrations
Tiered pricing scales credits and brand/seat counts predictably as you grow

Cons

Entry price of $299/month prices out smaller teams and solo operators
Registered in Gibraltar rather than a major market, worth noting for enterprise procurement review
