Every template below now uses wording for the selected profession.
Select any highlighted detail to fill it in.
Reassure the customer that the slot is safely reserved.
Hi {first_name}, your {service} with {business} is booked for {date} at {time}. Reply if you need help.
Send once the appointment is in the calendar and the time is genuinely reserved.
Caution
Only call the appointment confirmed if the slot is actually reserved.
Refresh the commitment while there is still time to change it.
Hi {first_name}, a reminder that your {service} with {business} is tomorrow, {date}, at {time}. Location: {location}. Reply if you need to make a change.
Use as the main reminder for an in-person appointment, home visit, class, or group session.
Caution
Check that the time and location were updated after any earlier change.
Ask for one unambiguous action before a clear deadline.
Hi {first_name}, please confirm your {service} with {business} on {date} at {time}. Reply YES by {confirm_deadline}, or reply CHANGE if the time no longer works.
Use when staffing, preparation, or a high-demand slot depends on an explicit confirmation.
Caution
Do not ask the customer to reply if replies are not monitored or supported.
Put the start time, time zone, and fallback in one place.
Hi {first_name}, your {service} starts at {time} ({timezone}). If you need help joining, call {phone}. - {business}
Send shortly before a virtual appointment, webinar, or online class begins.
Caution
Check the calendar invitation and show the time zone before sending.
Lead with concern and make a scheduling mix-up easy to fix.
Hi {first_name}, we missed you at {time} today and wanted to check that you're okay. If this was a scheduling mix-up, reply here and we'll help you find another time. - {business}
Use after a first missed appointment when the relationship matters more than immediate policy enforcement.
Caution
Keep the first welfare check separate from fee language and avoid sensitive service details.
Confirm the new time and explicitly retire the old one.
Hi {first_name}, your request is confirmed: {service} has moved from {old_date_time} to {new_date_time}. The old time is no longer active. - {business}
Send after accepting a customer-requested reschedule and updating the calendar.
Caution
Cancel any queued reminder for the old time before sending this confirmation.
Share arrival and preparation essentials without overloading the message.
Hi {first_name}, we look forward to your first {service} on {date} at {time}. Please arrive {arrival_minutes} minutes early and bring {what_to_bring}. Location: {location}. - {business}
Use for a new customer who needs arrival, access, document, or preparation guidance.
Caution
Keep preparation and arrival instructions short and essential.
State the deadline and what happens next without sounding threatening.
Hi {first_name}, we haven't received confirmation for your {service} on {date} at {time}. Your appointment is still booked. Please reply YES by {confirm_deadline}. If the time no longer works, call {phone}. - {business}
Use after a clear confirmation request has gone unanswered and there is a real operational next step.
Caution
Check delivery and reply history first; do not change the appointment state because a response was late.
Give the customer time to release the slot before a fee applies.
Hi {first_name}, your {service} is on {date} at {time}. Changes made after {cancel_deadline} may incur a {fee} fee. Reply or call {phone} before then if you need to cancel or reschedule. - {business}
Use when a disclosed cancellation window matters and the customer can still act before it closes.
Caution
Use only with a clearly disclosed policy and leave room for genuine exceptions.
Prompt the preparation or travel action needed today.
Good morning {first_name}. Your {service} is today at {time} at {location}. Please {preparation}. Questions? Call {phone}. - {business}
Use when a same-day prompt helps with travel, access, clothing, documents, or materials.
Caution
Send at a reasonable local time and make the preparation instruction specific.
Own the disruption, apologise, and give a simple next step.
Hi {first_name}, we're sorry, but {business} needs to move your {service} on {old_date_time}. Please reply with a suitable new day and time, or call {phone}. We apologise for the inconvenience.
Use when the provider or business cannot keep the original appointment.
Caution
State whether the old appointment is cancelled; do not treat a proposed time as accepted.
Acknowledge the update and make the remaining grace period clear.
Hi {first_name}, thanks for letting us know you're running late. We can hold your {service} until {grace_time}. Please reply with your ETA. After that, we may need to reschedule. - {business}
Use after a customer says they are delayed and you can offer a defined grace period.
Caution
Do not promise the full service if the remaining appointment time makes that impossible.
Give an honest estimate and let the customer raise a conflict.
Hi {first_name}, {provider} is running about {delay_minutes} minutes late for your {service}. Your appointment is still going ahead at approximately {new_time}. Reply if this causes a problem. We're sorry for the wait.
Use as soon as a provider delay is likely to affect the customer’s start time.
Caution
Update the customer again if the estimate changes instead of leaving a vague delay.
Document the missed appointment and point questions to a human.
Hi {first_name}, our records show that your {service} on {date} at {time} was missed. Under the policy agreed on {policy_date}, a {fee} no-show fee has been applied. Questions or an exceptional circumstance? Please call {phone}. - {business}
Use only after checking the appointment state, policy acceptance, and any known exception.
Caution
Verify attendance and policy consent before sending; a mistaken fee notice damages trust.
Offer the exact time with a reply deadline and no false promise.
Hi {first_name}, a {service} slot has opened on {date} at {time}. Reply YES by {reply_deadline} if you'd like it. The slot is first-come, first-served until confirmed. - {business}
Use for a customer who asked to hear about earlier or last-minute availability.
Caution
Say whether the offer is first-come-first-served and notify people when the slot is filled.
Acknowledge the mistake without exposing the intended customer.
Thanks for letting us know. We've removed this number from appointment reminders. Please don't share any personal information. If another message arrives from {business}, call {phone}.
Use only after the reported number has been removed from the appointment record or suppressed from further reminders.
Caution
Replying alone does not stop future messages; update the record and do not reveal any customer or appointment details.
No templates match.

Keep the message useful
A useful reminder answers four questions quickly: who is the appointment with, what is happening, when is it, and what should the customer do if something has changed?
There is no single best time for every reminder. Send each message early enough for the customer to take the action it asks for.
Confirm
Confirm the slot and correct any date, time, or location mistakes while the booking is still fresh.
Prepare
Give enough notice for preparation, confirmation, cancellation, or rescheduling.
Arrive
Repeat the time, location, or joining instructions without adding new information at the last minute.
