Appointment reminder message templates
An appointment reminder is a short message sent about a day before to someone who booked with you. Name the day, time and place, and make it easy to confirm or move the booking with a one-word reply.
When to use it
Send one reminder to each person who booked, about 24 hours before the appointment. For early-morning slots, the afternoon before works better than first thing on the day.
A reminder belongs to a conversation the customer started when they booked, so send it in that same chat, on the channel they booked through. It is a reply to one person, never a list broadcast.
Ask for an answer. A message that invites a quick yes or a request to move the time keeps the chat two-way, which is better for the customer and better for the account.

Copy a template, replace the words in square brackets, and read it once before you send it. Change anything that does not sound like you, because customers answer messages that sound like a real person who knows them.

Hi [name], your [service] is tomorrow at [time]. To get the most from it, please [preparation, for example arrive 10 minutes early or bring your previous notes]. Reply YES to confirm.What to avoid
- Sending the same reminder to your whole contact list at once. Each reminder goes to the one person who booked.
- Reminding people who never booked, or who booked another way and never gave you this number or profile.
- Several reminders for one booking. One reminder at the right time is enough for most businesses.
- Opening with fees or warnings. If you have a cancellation policy, mention it calmly at the end.
- Leaving out who the message is from. Always name the business so the customer knows who is writing.

When a customer has a booking tomorrow, send them one reminder in the chat they booked through, about 24 hours before. Include the day, time, service and address, and ask them to reply YES to confirm or tell us if they need a new time. If they want to move it, offer two open slots and confirm the new time in writing. Never send reminders to anyone without a booking, and never to a list.Channel rules that apply
- WhatsApp. WhatsApp restricts automation and bulk sending on ordinary and Business app numbers, so treat automated sending as a risk you manage rather than one you remove. Reply in chats customers started, and never broadcast these messages to a list. Spaces keeps a connected number to at most 200 messages and 10 new chats a day, and a newly connected number warms up over four weeks. WhatsApp limits
- Instagram. Instagram only lets you message someone who has not replied inside its messaging window, so replies in existing chats work best. Reply to people who messaged you, commented or asked to hear from you. Instagram limits
- Messenger. Like Instagram, Messenger limits messages to people who have not replied, so replies in existing chats work best. Keep to people who wrote to your Page first. Messenger limits
- LinkedIn. A normal message goes to a 1st-degree connection. Anyone else needs a connection request or an InMail. Use these with clients and contacts who already know you. LinkedIn limits
- Email. A new chat here is a new email thread. Replies on a thread someone started are not held back by the warm-up. Spaces sends one email at a time to one person, never bulk email. Email limits
Spaces lowers the risk of a restricted account with enforced limits, warm-up and pacing, but no tool can guarantee a platform will not act on an account. How Spaces keeps accounts safe.
FAQ
When should I send an appointment reminder?
About 24 hours before is a good default, because it gives the customer time to rebook if something has changed. For early-morning appointments, send it the afternoon before. One reminder per booking is enough for most businesses.
Should a reminder ask the customer to confirm?
Yes. A short “Reply YES to confirm” makes it easy to answer, tells you who is still coming and keeps the conversation two-way rather than a one-sided notice.
Can I send WhatsApp appointment reminders automatically?
WhatsApp restricts automation on ordinary numbers, so automated sending always carries some risk. If you use it, keep it to one person at a time, only people who booked, and inside safe limits. Spaces can schedule a message for each booking and keeps every account inside its limits, which lowers the risk but cannot remove it.
Can I send this appointment reminder message to all my customers at once?
No. Send each message to one person who contacted you, booked or bought from you. Bulk messages on WhatsApp, Instagram or Messenger are one of the quickest ways to get an account restricted, and Spaces refuses the same cold message sent to many people. A message written for one conversation also gets far better replies.
Can my AI agent use these templates for me?
Yes. Connect your accounts to Spaces and your AI agent can read each chat and reply in your words, using the note on this page as a guide. A scheduled message or a routine can also send a set reply at a time or on a trigger; routines send the exact words you give them and are not an AI. You can turn on approvals so nothing goes out until you say yes, and every message stays inside the account’s sending limits.
Let your AI agent answer for you
Spaces connects your own WhatsApp, Instagram, LinkedIn, Messenger, X and email accounts to the AI agent you already use, so it can reply in your words and keep every account inside safe sending limits. No card needed to start a trial.
