The short version

  • Each has a real cost: CallRail the 250 included minutes on the entry plan are very low, and independent analyses put realistic SMB spend at one and a half to three and a half times list, so a $50 plan commonly bills $100 to $250.; 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: CallRail covers Dynamic Number Insertion, 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.

CallRail

  • The 250 included minutes on the entry plan are very low, and independent analyses put realistic SMB spend at one and a half to three and a half times list, so a $50 plan commonly bills $100 to $250.
  • Tracking numbers cost $3 each per month beyond the included five, so cost scales with attribution granularity rather than with value; a twenty-location business at three numbers per site pays $165 a month in number fees before any call connects.
  • Spam and unanswered calls consume billable minutes, and CallRail has been unclear with users about whether robocalls count against the allowance, which turns a nuisance into a line item.
  • Multiple public reviewers report cancellation friction, including counter-offers and stalling, charges continuing after account closure, and in one case an unexpected $500 charge months after cancelling.
  • Tier gating runs on two axes: form tracking and Conversation Intelligence sit on different plans, so having both means jumping to the $195 tier, and you cannot buy transcription onto the cheapest plan at any price.
  • Number inventory, key integrations and compliance posture are built for North American SMBs, so international number availability and non-US coverage are materially weaker.

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

CallRail: What will I actually pay?

More than list. Budget 1.5x to 3.5x the plan price once numbers beyond the included five and minutes beyond the allowance are counted.

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.

CallRail: Do spam calls use my minutes?

Yes, minutes are consumed regardless of whether a call was answered or was a robocall. Users report this is a meaningful share of the overage on some accounts.

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.

CallRail: Can I get call transcription on the cheapest plan?

No. Conversation Intelligence starts at the $150 Lead Conversion tier. There is no add-on route from $50.

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.

CallRail: Is there a free trial?

Yes, 14 days, self-serve, no sales call required.

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.
