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.

Whatagraph

  • The entry Max plan starts at 699 EUR per month and is billed annually, with no monthly billing option shown
  • Only two plans exist and the Prime plan is custom priced with no published rate
  • Public API access, transfer to BigQuery and Looker, a custom report domain and premium integrations all require the Prime plan
  • Data sources are metered as credits at 1 credit per connected data account, so each additional ad account consumes quota
  • Extra credits can be bought only up to the next plan threshold, after which an upgrade is required
  • Moving to either the Max or Prime plan requires booking a call with sales rather than self-serve upgrade
  • The free trial is 14 days
