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.

Shopify Collabs

  • A 2.9% processing fee is applied to every automatic commission payment and charged to the merchant's Shopify bill
  • Requires a Shopify store, so it is unusable by brands not selling on Shopify
  • Commissions are handled in USD and merchants billed in another currency pay local conversion fees
  • Creators who do not submit a W9 have their annual payouts capped at $599.99 USD
  • Collabs is not accepting new creator signups, so brands can only work with creators already on the platform or invited directly

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