Appointment Reminder Sequence (Email + SMS)
A 3-message reminder — email about 24 hours before, a short SMS the morning of, and one no-show note only if they miss — that cuts no-shows without guilt or a made-up cancellation fee.

The prompt
Write a 3-message appointment reminder sequence the owner of [BUSINESS_NAME], a [BUSINESS_TYPE], can send to [CUSTOMER_NAME] for a booked appointment.
Appointment details:
- Business name: [BUSINESS_NAME]
- Business type: [BUSINESS_TYPE]
- Customer first name: [CUSTOMER_NAME]
- Appointment type: [APPOINTMENT_TYPE]
- Date: [APPOINTMENT_DATE]
- Time: [APPOINTMENT_TIME]
- Where they go, or the video link: [LOCATION_OR_LINK]
- Rebook or reschedule path: [REBOOK_LINK] (a real URL, or the exact phrase "reply to this message" if there is no link)
- Cancel or reschedule window, or "none": [POLICY_NOTE]
- Sender first name: [SENDER_NAME]
Write all 3 messages now. Messages 1 and 2 go out before the appointment. Message 3 is written now but sent only if they no-show.
1. Email, about 24 hours before. Two subject-line options, then the body. Under 120 words.
2. SMS, the morning of the appointment. If the appointment is before 10 a.m., time this for about 2 hours before instead of a generic morning text. One message. Under 160 characters when the name, time, and reschedule path fit.
3. No-show recovery. Choose email or SMS and label which one. Under 100 words. One clear rebook path. Send only if they missed the appointment.
Message 1 (email) must:
- Put [APPOINTMENT_TYPE], [APPOINTMENT_DATE], [APPOINTMENT_TIME], and [LOCATION_OR_LINK] in the first two sentences.
- Give one step to confirm or reschedule. If [REBOOK_LINK] is a URL, that URL is the step. If [REBOOK_LINK] is blank or "reply to this message", tell them to reply to this email. Do not invent a booking link, a phone tree, or a second CTA.
- Sound like [SENDER_NAME] at [BUSINESS_NAME]. Owner or front desk. Not a booking app, not a spa ad.
- Mention [POLICY_NOTE] once, in one sentence, only when a real cancel or reschedule window was provided.
Message 2 (SMS) must:
- Lead with the time and [APPOINTMENT_TYPE].
- Include how to cancel or reschedule in the same text: the [REBOOK_LINK] URL, or "Reply to cancel or reschedule" when there is no link.
- Stay under 160 characters when the facts fit. If they do not fit, drop the street address before you drop the time or the cancel/reschedule line. Do not drop either of those.
- No marketing sentence, offer, emoji, or "we can't wait to see you".
Message 3 (no-show recovery) must:
- State that the appointment time passed and they were not there. No guilt, no shame, no "you wasted the slot", no "we held this for you".
- Offer exactly one rebook path: the [REBOOK_LINK] URL, or reply to this message if there is no link.
- Say, in the output label, that this message is sent only if they no-showed. Do not tell the customer to ignore it. Do not pre-schedule it.
- Do not also ask for a review, a referral, or a reason.
Rules for every message:
- Use [CUSTOMER_NAME].
- If [POLICY_NOTE] is blank or "none", do not invent a cancellation fee, no-show fee, deposit, or a deadline. Do not write "no fee" either. Leave policy out entirely.
- If [POLICY_NOTE] states a real fee, mention that fee only in the no-show message, once, in the words given. Do not add a fee to the reminder email or the SMS.
- No "I hope this finds you well", "just a friendly reminder", "just circling back", fake urgency ("last chance", "spots are filling up", "act now"), or spa marketing ("pamper yourself", "your glow awaits", "treat yourself", "we can't wait").
- No upsell.
- Sign email with [SENDER_NAME] and [BUSINESS_NAME]. SMS can skip a formal sign-off. Put [BUSINESS_NAME] once in the SMS.
Output in this order:
EMAIL (~24 hours before): SUBJECT A / SUBJECT B, then the body.
SMS (morning of, or ~2 hours before if the appointment is before 10 a.m.): the text, then the character count.
NO-SHOW RECOVERY (send only if they missed — do not send if they cancelled): email or SMS, then the message.
A one-line note on whether a cancel window or fee was included, based on [POLICY_NOTE].
