The short version

  • Only Kissmetrics has a free tier, so it costs nothing to try first.
  • Each has a real cost: Kissmetrics overages are added automatically to the next invoice rather than blocked, so exceeding an event allowance bills without a decision point; 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.
  • They diverge on capability: Kissmetrics covers Customer analytics, Postscript covers Shopify segmentation.
  • Prices and features above 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.

Kissmetrics

  • Overages are added automatically to the next invoice rather than blocked, so exceeding an event allowance bills without a decision point
  • The free plan allows 100,000 events a month
  • Per event rates fall with volume, from $0.20 per 1,000 events on Growth to $0.10 on Gold, so smaller customers pay double per event
  • The vendor states Growth, Silver and Gold are the identical product, so the paid tiers differ only in unit price and volume
  • Anything above 5 million events is custom priced

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.
