Your Waitlist Is Full. Your Schedule Shouldn't Have Gaps.

FullSlot connects directly to Calendly. The moment a cancellation happens, we detect it automatically and notify your waitlist — no action needed from you.

Yes. FullSlot stores only client contact info — name, email, phone. No session notes, no diagnoses, no clinical records. All data is encrypted in transit and at rest and is never sold or shared. The notification clients receive says nothing about their reason for seeking therapy.

The message says a session slot just opened up and gives them a link to book it. It doesn't mention anyone else, their history, or anything sensitive. You can also customize the message template entirely.

No. They get a text with a link. Tap it, confirm, done. No app, no login, no account to create.

First to click gets it. If someone else already booked, they'll see it's taken when they tap the link. No double-booking, no awkward calls.
