What will cost you money if you skim itThe $0 a month is not free — it carries a $49 monthly minimum spend, which means $49 is your floor whether you send anything or not.

Cost-trap flags — each with its evidence

🧮 Usage-metered — Credits, overages or percentage fees on top of the subscription
“Read the tiers as what they are: a platform fee plus a per-message rate plus carrier fees that the page will not quantify.”

Genuinely good for

Shopify stores with a list large enough that SMS beats email on response — the per-message economics only work once volume justifies the platform fee

Skip it if

you are testing whether SMS works for you at all — the $49 minimum spend on the free tier means the experiment has a floor, and the carrier fees are an unknown you cannot price up front

The honest comparisonAttentive or Klaviyo SMS — the direct SMS peers for ecommerce — compare total cost at your real monthly send volume, including carrier fees, not the platform fee

Work at Postscript? This page is yours the moment you claim it.

Write your own description and it appears at the top of this page, in your words, free — no fee during beta and no strings. What does not change: our research stays exactly where it is, underneath, and you cannot edit it. That is the point of the page. Two honest caveats before you bother: our audience is still modest and growing, and the outbound link is nofollow ugc, so this is not an SEO play.

We have pre-filled the name, site and category we already have on file, so the only thing left to write is the description. A claimed page also drops the noindex we keep on research-only pages.
