Postscript Pricing Explained

Postscript pricing is built around ecommerce SMS marketing, so message volume and carrier costs matter more than email contact tiers.

Updated Jun 17, 2026·1 checked source·Independent guide
Quick answer

Postscript's official pricing page is for ecommerce SMS marketing, not traditional email marketing. The page positions Postscript around Shopify SMS subscriber growth, campaign sending, automations, two-way conversations, attribution, and compliance. Postscript offers four plans: Starter (free platform fee, pay-per-message at $0.015/SMS and $0.045/MMS), Growth (around $100/mo), Professional (around $500/mo), and Enterprise (custom). Buyers should model software package cost, SMS and MMS message volume, carrier fees, subscriber growth, and whether Postscript's ecommerce SMS workflow replaces or complements an email platform.

Check fit

SaaS lifecycle email

Postscript: Postscript's SMS/ecommerce focus is the wrong tool.. Sequenzy: Sequenzy maps to SaaS lifecycle email.. Sequenzy is better for email-led SaaS journeys.

Check fit

Email plus SMS stack

Postscript: Postscript may complement an email provider rather than replace it.. Sequenzy: Compare whether Sequenzy covers the email portion.. Treat Postscript as SMS infrastructure in a broader stack.

What to watch for

SMS pricing can include message volume and carrier-related costs.

Postscript is not a full email marketing replacement.

It is ecommerce and Shopify-oriented.

Postscript pricing is SMS-first

Postscript pricing should be evaluated by SMS subscriber growth, campaigns, automations, message volume, and carrier cost assumptions.

The expensive part of SMS is rarely the plan name. It is message volume, MMS use, carrier fees, compliance, and how often the store sends promotional campaigns or triggered flows. Postscript can be a revenue channel for ecommerce teams, but it should not be treated as a replacement for email lifecycle software unless SMS is genuinely the center of the retention strategy.

For ecommerce SMS comparisons, start with Postscript alternatives. For SaaS teams, Sequenzy vs Postscript makes the category difference clearer: customer lifecycle email versus Shopify SMS revenue.
