Appointment Reminder Agent: questions to ask

From The AI Agents Report by Iterategy · iterategy.com/research/ai-agents/jobs/appointment-reminder-agent/

The nine questions

Does an AI do this, or does a rule? If the answer is “when X happens it sends Y”, you are buying automation, and it should not cost AI prices.
Does it send, or does it draft? Ask for the sentence on their page that says it acts on its own.
Does it do it on its own on this plan, or on the one above? The setting that lets it act without you is often a tier up from the entry price.
What does it do with the hard cases? Ask what it holds back for you, and what happens to what it cannot resolve.
What is the cap, and what happens past it? Work out the bill at the volume you actually do, not at the included allowance.
What is the unit? Per month, per user, per location, per minute, per credit or per resolved ticket.
Who does the setup, and is it in the price?
What happens to the changes it made when I stop paying? Some tools make changes that stay only while you subscribe.
Who carries the legal side? For calling and texting customers, ask who handles consent and opt-outs.

Almost every reminder product sends on the appointment clock from a template you wrote. That is automation, and it often comes inside your booking software already.
The useful difference is what happens with the reply. Ask whether it reads the reply and moves the booking, or just sends a link to rebook.
Only 2 products we found put an AI in this job. Voice versions bill by the minute, so price one at your real number of appointments.
In reviews, the complaints are about slow apps, billing and support, not reminders failing to go out.
