The short version

  • Only eWebinar has a free tier, so it costs nothing to try first.
  • Each has a real cost: eWebinar the subscription level is set automatically by how many active eWebinars you have, so the bill moves up on its own as you publish more; 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: eWebinar covers Evergreen webinars, 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.

eWebinar

  • The subscription level is set automatically by how many active eWebinars you have, so the bill moves up on its own as you publish more
  • Level 1 at $99 per month allows only one active eWebinar and 1,000 registrants per month
  • Level 3 at $299 per month covers 15 active eWebinars and charges $15 per month for each additional one
  • Extra registrants are sold only in blocks of 1,000 at $49 per month per block
  • Removing the 'Powered by eWebinar' branding costs $99 per month on top of the subscription
  • Using your own custom domain costs $99 per month extra
  • The Salesforce integration is a $249 per month add-on and the Marketo integration is $179 per month
  • Advanced access control, which restricts who can join by email domain, is a $49 per month add-on
  • The universal cross-webinar dashboard is a $229 per month add-on
  • Enterprise registrant volumes and active webinar counts are quoted by sales with no published rate

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.
