Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Postscript

  • Carrier pass-through fees are billed on top of the per-message rate, roughly $0.00418 per SMS and $0.00841 per MMS in the United States, and are routinely missing from the cost comparisons buyers build.
  • The cheapest per-message rates require the $500 a month plan, so a small sender pays more than double the headline low rate per text.
  • The $0 Starter plan carries a $49 minimum monthly spend, so it is not a free tier and quiet months still generate a bill.
  • US SMS marketing carries real legal exposure under consent, quiet hours and carrier registration rules, and the compliance obligation sits with the merchant, not the platform.
  • It is SMS and MMS only, so email, push and on-site messaging live in a separate tool and audience suppression between the two has to be managed across systems.

Sogolytics

  • Its statistical analysis and text analytics capability is noticeably shallower than Qualtrics or Medallia for serious market research work.
  • The free tier response cap, around 100 per project and 200 a year, is restrictive enough that most real programmes need a paid plan quickly.
  • Its enterprise integration and panel access ecosystem is smaller than the larger experience management platforms, limiting it for organisations with complex data pipeline needs.
  • Reported pricing varies noticeably between sources depending on billing term and promotional pricing, so buyers should confirm the current rate directly rather than relying on older reviews.
  • Brand recognition still lags its former name, SoGoSurvey, in some buyer searches, which can create confusion when comparing reviews written before the 2021 rebrand.

Answered from the vendors’ own pages

Postscript: Is Postscript only for Shopify?

It is built for Shopify and that is where its segmentation advantage lies, but headless and non-Shopify stores are supported through an SDK with more setup work.

Sogolytics: Is Sogolytics the same company as SoGoSurvey?

Yes, it rebranded from SoGoSurvey to Sogolytics in 2021 with a broader experience management positioning.

Postscript: What is the real cost per text?

The plan rate plus carrier fees. On Starter that is about $0.015 plus roughly $0.00418 in US carrier fees per SMS, so budget close to two cents a message before discounts.

Sogolytics: Is there a free plan?

Yes, capped at around 100 responses per project and 200 responses a year.

Postscript: Is the Starter plan free?

No. The base fee is $0 but there is a $49 minimum monthly spend, so it functions as a $49 floor.

Sogolytics: How does it compare in price with Qualtrics?

Sogolytics publishes monthly self-service pricing from around 39 USD a month, versus Qualtrics enterprise contracts that typically run into five figures annually.
