The short version

  • Fillout has a free plan, then $15/mo; Postscript starts at $49/mo.
  • Only Fillout lists unlimited seats and forms; only Postscript lists shopify segmentation.
  • Where Postscript falls short: 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.
  • Prices and features on this page were last checked on 31 August 2026.

Where each one falls short

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

Fillout

  • The Business plan is marketed with unlimited responses but the fair use policy names thresholds of 30,000 submissions a month, 250,000 in total, 500 forms per account and 50 GB of uploads a month, above which the vendor may limit or suspend features, so unlimited means unmetered rather than uncapped
  • EU data residency begins on the Team plan at 250 USD per month, more than three times the Business price, and is not applied automatically; you must upgrade and then raise a support request to be moved
  • The Team plan is hidden behind a secondary tab that does not render without interaction, so buyers reading the pricing page see Business at 75 USD as the top self-serve tier and only discover the 250 USD step when they ask for single sign-on or EU hosting
  • The enterprise marketing page lists hosting in the United States, EU, United Kingdom, Australia and Canada, but the security documentation and subprocessor list name only the United States and the EU, so three of those five regions should be confirmed in writing before they are relied on
  • The vendor is SOC 2 Type 2 but claims neither ISO 27001 nor HIPAA anywhere in its documentation, and it is angel-funded with no disclosed institutional round while the parent company now trades as Zite and ships a separate AI application builder

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

Fillout: Are seats really unlimited?

Yes. The vendor states there are no per-seat charges on any plan, including Free, and forms are unlimited too. Responses per month is the only meter below the Business tier.

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.

Fillout: What happens when I exceed my response quota?

Nothing breaks. Forms keep collecting, and you can upgrade, buy bulk submissions or wait for the monthly reset.

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.

Fillout: Can I host respondent data in the EU?

Only from the Team plan at 250 USD per month, and only after contacting support to switch. Note that email and payment subprocessors remain in the United States regardless.

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.

Fillout: Is the Business plan really unlimited responses?

It is unmetered, not uncapped. The fair use policy names roughly 30,000 submissions a month as the point at which the vendor may intervene, so treat that as the practical ceiling.

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.
