Q: Is Postscript cheaper than Klaviyo?

It depends on your setup. Postscript can be cheaper if you already use a separate low-cost email tool and want a specialist SMS platform. Klaviyo can be more efficient if you want one platform for both email and SMS.

Estimated Postscript Cost Breakdown

Tier	Estimated Platform Fee	Typical Brand	Notes
Starter	~$100/mo	Smaller Shopify stores	Basic flows, campaigns, core SMS tooling
Growth	~$500/mo	Scaling DTC brands	More support, stronger infrastructure, more volume
Enterprise	Custom	Large brands	Negotiated pricing, higher-touch support

The real lever is usage: SMS and MMS volume can quickly exceed the platform fee. A brand sending large campaign volumes may pay materially more in message costs than in subscription fees.

What Drives the Bill Up

There are four main drivers: subscriber growth, campaign frequency, automation volume, and MMS usage. If your retention team sends frequent promotions and runs multiple flows, your SMS bill compounds quickly. That is not a Postscript problem specifically. It is the economics of SMS.

When Postscript Is Worth It

Postscript is worth it when you are on Shopify, SMS is an intentional revenue channel, and you want a specialist tool instead of an all-in-one stack. It becomes less compelling when you want email and SMS in one system or when your team is trying to simplify vendors.

Postscript vs Klaviyo Pricing

Klaviyo can look more expensive on paper, but if it replaces both your ESP and your SMS tool, the overall economics can be better. Postscript wins when you explicitly want best-in-class Shopify SMS and are comfortable running email elsewhere.

Postscript vs Attentive Pricing

Attentive is usually pricier and more service-heavy. Postscript is the more accessible option for Shopify-native brands that want strong SMS performance without committing to a bigger enterprise-style relationship.

Frequently Asked Questions

Does Postscript charge per text?

Yes, effectively. The platform fee is only one part of the bill. Message usage is a major part of total cost.

Is Postscript cheaper than Klaviyo?

Sometimes, but not always. It depends on whether you compare standalone SMS software or the total cost of your full retention stack.

Who should avoid Postscript?

Brands that are not on Shopify, brands that want email and SMS in one platform, or very small stores with minimal SMS ambitions should usually choose something else.
