Send four appointment reminder emails: one a week before, one two days before that asks for a one-word reply, one on the morning of, and a reschedule note for anyone who has not answered. Each carries what a text cannot, which is the address, what to bring and a link. Copy the four below and change the details.
Marlowe Tax Services is a two-person office in Dayton, Ohio. Clients book a 45-minute return appointment weeks ahead, and they have to arrive with the right paperwork. Before the reminders, about 6 of every 40 appointments in a month ended in a no-show or a half-empty folder. At $150 an appointment, six lost slots is $900 a month. These four emails are what they send now. The numbers are an example of the stakes, not a promise of what yours will do.
The timeline at a glance
| Send | Job of the email | Ask |
|---|---|---|
| 7 days before | Prepare them | Gather the list, tell us if the date changes |
| 2 days before | Get a commitment | Reply YES to keep the slot |
| Morning of | Remove friction | None, just logistics |
| Day before, if no reply | Free the slot or confirm it | Reschedule link |
Email 1, a week out: what to bring
Use it when the appointment was booked more than a week ahead, or the person has to prepare something.
Subject: Your return appointment on Tuesday, March 4 at 10:30
"Hi Dana, you are booked with Marlowe Tax on Tuesday, March 4 at 10:30 a.m., at 118 Court Street, Suite 2 (free parking behind the building). Please bring your W-2s and 1099s, last year's return, and a photo ID. If the date no longer works, use this link to pick another: [link]. See you then. Tessa"
It works because the subject line holds the date, so the email is useful in a search later. Variation: for a video appointment, replace the address with the call link and a line such as "Test it once before the day."
Email 2, two days out: the one-word reply
This is the email that does the most work. Use it for every appointment, and expect to read the replies yourself.
Subject: Still good for Tuesday at 10:30? Reply YES
"Hi Dana, your appointment with Marlowe Tax is the day after tomorrow, Tuesday at 10:30. Please reply YES to keep your spot. If something has come up, tell us now and we will move you to another day, and someone else can have the time. Tessa"
Why it works: asking for a reply turns a passive notice into a small commitment, and a person who typed yes is more likely to turn up than one who skimmed a note. It also tells you in advance who is a risk. Variation: if you serve people who do not answer email, send the same words as a text; how to confirm appointments by text has the wording and the consent rules.
Email 3, the morning of: logistics only
Send it at 7 a.m. Keep it to three lines.
Subject: Today at 10:30, 118 Court Street
"Good morning Dana. See you at 10:30 today at 118 Court Street, Suite 2, back lot parking. The office phone is 555-0142 if you are running late. Tessa"
It works because the address and the phone number are in the subject and the first line, which is where someone looks while standing in a driveway. Variation: add "The building door locks at 9, so ring suite 2" if it applies.
Email 4, the reschedule note for silence
Send this the evening before to anyone who did not answer email 2. It frees the slot if they will not use it.
Subject: Need to move your Tuesday appointment?
"Hi Dana, we have not heard back about tomorrow at 10:30. If you can still come, no need to reply, we will see you. If not, this link lets you pick another time in a few seconds, and it gives the slot to someone on our waiting list: [link]. Tessa"
It works because it makes the polite option easy. Most people who intend to cancel do not like writing "I can't come." Variation: for high-value slots, call the people who still have not answered; the email plus one call is cheap next to an empty hour.
Subject lines that get read
Put the date and the time in the subject, not "Reminder." Good ones are specific and short: "Tuesday at 10:30 with Marlowe Tax", "Still good for Tuesday? Reply YES", "Tomorrow 10:30, 118 Court Street", and "Need to move your appointment?" Avoid exclamation marks, all capitals and the word "urgent," which can trigger spam filters on an ordinary reminder.
Keep track of who confirmed
A spreadsheet with three columns is enough: confirmed, no reply, wants to move. Update it after email 2. Anyone in "no reply" gets email 4 and, for the best-paying slots, a phone call. Count no-shows monthly; how to reduce no-shows for appointments covers that and deposits. If an appointment came from a new lead, the first reminder can double as the start of your follow-up; follow-up text messages for leads has the short version.
One legal point. A reminder about something the person booked is a transactional email, which US rules treat more lightly than marketing mail. Keep sales offers out of it so it stays that way. If you are in healthcare, keep clinical details out of email altogether and follow your own privacy obligations. This is general information, not legal advice.
Reminders only work if every booking is recorded
Reminders depend on bookings being in the system. Many customers tell you a day by phone or reply, and a link they never click leaves that appointment unrecorded; booking into Google Calendar without a link covers it. The booking itself starts earlier, with the first reply to a new lead; speed to lead automation shows how to set that up, and what an appointment setter does describes the person whose job it is. Rocketship's AI worker books meetings straight onto your calendar and can answer the number you already have, so appointments land where the reminders can find them. Rocketship finds the buyers, emails them from your own Gmail, follows up, and books the meeting on its own. Plans that get you customers start at $24.99 a month (Launch), and both Launch and Frontier start with a 7-day free trial, card required. Answering your existing number works on Launch, with call minutes bought as you go ($15 for 50), and a dedicated line is $5 a month. See also the AI workers.
