Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Demio

  • The Starter plan at $45 a month billed annually caps attendees at 50 and sessions at 3 hours
  • Automated and pre recorded on demand webinars are excluded from Starter, so the entry plan is live only
  • 1080p streaming, restreaming, live captions, auto transcriptions and custom domains are all Premium only
  • Attendee capacity is a priced tier within a plan rather than a soft limit, at 150, 500, 1,000 or 3,000
  • Only Premium, at $196 a month billed annually, removes the host limit

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.
