  • They diverge on capability: Alchemer covers Deep question logic, Postscript covers Shopify segmentation.

Where each one falls short

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

Alchemer

  • More expensive than the simple form builders, which is the fair comparison for a short survey
  • The interface carries a long product history and is less immediately friendly than newer tools
  • Advanced logic is powerful and correspondingly easy to misconfigure, and testing a complex survey is real work
  • Named Alchemer since 2020, so much of the searchable material still says SurveyGizmo

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.

Answered from the vendors’ own pages

Alchemer: What does Alchemer cost?

Tiered annual subscriptions published on the vendor site. Check current rates there.

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.

Alchemer: Is Alchemer the same as SurveyGizmo?

Yes. SurveyGizmo was renamed Alchemer in 2020, which is why older reviews and documentation use the former name.

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.

Alchemer: When is it worth more than a simple form builder?

When the questionnaire has real conditional logic, or when responses need to route into Salesforce or a data warehouse.

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.

Postscript: Do I need a contract?

No. Contracts are offered but not required, and plans can be moved up or down at any time under usage-based billing.
