Texting
Texting with the assistant: live on SMS and WhatsApp
Customers can message your Amfion number over SMS or WhatsApp and the same assistant answers: your services, prices, hours and policies, live availability, and real bookings, right in the thread. Conversations land in your Inbox next to calls and chats, with human takeover when you want it. US numbers require carrier registration for SMS (10DLC) and a Meta-approved WhatsApp sender; we handle both with you during onboarding.
Texting needs an Amfion number. Front Desk and Growth include one; Digital has no number unless you add the voice add-on ($149 a month, plus $10 a month for the number). The free trial does not include a number. See pricing.

What ships
What actually ships today: the email lifecycle engine
Reminders run through a queue-backed worker with a per-send uniqueness key, so a scheduling retry cannot produce a duplicate email. Marketing-class messages honor suppressions and always carry an unsubscribe link.
Booking reminders
Scheduled reminder emails ahead of an appointment, de-duplicated so a customer can never be emailed twice for the same booking. Off by default, because Cal.com may already be emailing your attendees.
Waitlist backfill
When a booking is cancelled, the freed slot is offered to waitlisted customers automatically. It is triggered by the cancellation webhook, not a nightly batch.
Rebooking nudges
Customers who are due to return get a nudge to book again. Honors per-customer suppressions and carries an unsubscribe link.
Review requests
A post-appointment request for a review, on the same suppression and unsubscribe rules.
Who sends the booking confirmation?
For services running on Cal.com, Cal.com sends the confirmation directly; Amfion does not duplicate it. That is why booking reminders default to off: turning them on without checking your Cal.com workflow settings is the fastest way to email a customer twice.
