Event Reminder Text Messages: Examples, Templates, and When to Send Them

Someone signs up for your webinar, appointment, class, fundraiser, launch event, or conference session. They are interested and they plan to attend, but then the event gets lost. It gets buried under meetings, inbox clutter, school pickups, travel, and other notifications.

That is why event reminders matter.

A good reminder strategy does not just “ping” people. It helps attendees remember why they signed up, know exactly when and where to show up, and take the right action at the right moment.

For most events, the strongest reminder strategy starts by getting the event onto the attendee’s calendar first. Then you can layer in email and SMS reminders where they make sense and add value. AddEvent helps organizers do this with an Add to Calendar button, Add to Calendar links, event landing pages, and other calendar-sharing tools that let attendees save events to calendar apps like Google Calendar, Apple Calendar, Microsoft Outlook, Office 365, and Yahoo Calendar.

Text message reminders can still play an important supporting role. SMS reminders are especially useful for time-sensitive events, high-value appointments, in-person logistics, webinars, and audiences that may not check email regularly. 

Research in outpatient hospital settings has found that appointment reminders, including SMS reminders, can improve attendance compared with no reminders, although results vary by context.

The best approach is not calendar reminders or text messages. It is calendar reminders first, then selective email and SMS reminders when immediacy matters.

What are event reminder text messages?

Event reminder text messages are short SMS messages sent before an event to remind attendees when the event is happening and what action they should take next.

A good event reminder text usually includes:

• The event name
• The date or start time
• One clear next step
• A useful link, such as a join link, ticket link, directions link, or event details page

Example Event Reminder Text Messages

Reminder: Product Demo Live starts tomorrow at 2 PM ET. Add it to your calendar or view details here: [link]

Or:

Product Demo Live starts in 1 hour. Join here: [link]

The best event reminder texts are short, specific, timely, and easy to act on.

To make sure your event gets on attendees’ calendars after they register, sending an Add to Calendar link via SMS is another great touchpoint to remind registrants to add your event to their calendar. This way registrants have the event on their calendar, and when you send your event reminder text message 

Example Event Confirmation Text Message

• You’re in! Your spot for the XYZ Event has been reserved. Add it to your calendar here: [Add to Calendar link]

Should you use SMS or calendar reminders for events?

Use calendar reminders as your primary reminder system and then use SMS as an additional nudge, not as the only way people remember your event.

Calendar reminders are powerful because they live where attendees already manage their time. Google Calendar, for example, allows users to receive event notifications on their phone, in a web browser, or by email, and users can specify their  notification settings for individual events or set a default notification setting for all of their calendar event notifications.

SMS reminders are powerful for a different reason: they are immediate and leave a notification badge on their app. A short text can work well when the attendee needs to act soon, such as joining a webinar, leaving for a venue, confirming an appointment, opening a ticket, or checking updated event details.

The recommended hierarchy is simple:

Reminder channel	Best use
Calendar reminder	Saving the event, blocking time, and triggering automatic device-level reminders
Email reminder	Sharing agendas, speaker details, prep materials, venue information, and follow-up
SMS reminder	Sending concise, time-sensitive nudges close to the event

For AddEvent users, the most important first step is making the event easy to save. An Add to Calendar button or Add to Calendar link lets attendees add the event to their personal calendar in one click.

When should I send event reminder text messages?

Send event reminder text messages when the reminder is timely, useful, and expected.

A text message should answer at least one of these questions:

1. What is happening?
2. When is it happening?
3. What should I do next?

For example, “Your webinar starts in 1 hour. Join here: [link]” is useful because it is specific and action-oriented. “Do not forget about our event next month!” is less useful because it is too early and does not help the attendees take action.

Best SMS reminder timing by event type

Event type	When SMS helps most	Example use
Webinars and virtual events	1 hour or 10–15 minutes before	Send the join link
Appointments or consultations	24 hours and 2 hours before	Confirm, cancel, or reschedule
In-person events	Morning of or 2–3 hours before	Share parking, check-in, room, or address details
Ticketed events	24 hours before and day of	Send ticket link, arrival time, or entry info
Multi-session events	Only for key sessions or changes	Send room changes, start times, or urgent updates
Classes and workshops	24 hours and 1 hour before	Share prep materials, directions, or class link

The closer the event gets, the shorter and more practical your text should be.

What is the best event reminder schedule?

For most events, the best event reminder schedule is:

Timing	Channel	Purpose
Immediately after registration	Confirmation email + Add to Calendar	Confirm the attendee’s spot and get the event on their calendar
1 week before	Email	Build interest and share prep details
24 hours before	Calendar reminder + email or SMS	Remind attendees the event is tomorrow and include key logistics
1 hour before	Calendar reminder + optional SMS	Prompt immediate action, such as joining, leaving, or checking in
10–15 minutes before	Optional SMS for virtual events	Share the join link when the event is about to start
After the event	Email	Send recording, recap, survey, or next step

AddEvent’s Notification Flows can automate email confirmations, reminders, follow-ups, and other event communications for RSVP events. New Notification Flows include default notifications for an immediate confirmation email after an attendee responds, a reminder 1 day before the event, and a reminder 1 hour before the event; organizers can edit, remove, or expand those notifications.

For most events, do not send every reminder through every channel. Use a layered system instead:

Step 1: Get the event onto the attendee’s calendar.
Step 2: Send email reminders when attendees need details.
Step 3: Use SMS only when the reminder needs immediate attention.

How many reminders should I send before an event?

Most events need three to four total reminders across all channels, including the confirmation message.

A practical reminder sequence looks like this:

1. Confirmation immediately after signup, with an Add to Calendar link
2. Reminder 24 hours before the event
3. Reminder 1 hour before the event
4. Optional final reminder 10–15 minutes before a virtual or time-sensitive event

For SMS specifically, keep it lighter. Most events only need one or two text reminders.

One SMS reminder is enough for simple events where the attendee already has the event on their calendar.

Two SMS reminders can make sense for appointments, paid events, in-person events, or webinars where the join link is critical.

Three or more SMS reminders should be reserved for unusual cases, such as multi-day events, urgent logistics, or high-stakes appointments where the attendee has clearly opted in.

The goal is not to send more reminders. The goal is to send the right reminder through the right channel at the right time.

How do I automate event reminder texts?

Start by automating the calendar add. Then automate supporting messages around it.

With AddEvent, you can create an event and share it through an Add to Calendar button, Add to Calendar link, hosted event landing page, embeddable calendar, events list, or QR code. Attendees can save the event to their personal calendar, and their calendar app can handle future reminders based on their settings.

For RSVP events, Notification Flows can automate email confirmations, reminder emails, follow-ups, and other event communications based on attendee response and event timing.

For SMS, connect your registration, CRM, event platform, or booking system to your SMS provider. A typical automated event reminder workflow looks like this:

1. Someone registers for your event.
2. They receive a confirmation email with an Add to Calendar link.
3. Their RSVP or registration data is stored in your CRM or event platform.
4. Your SMS platform sends approved reminders at scheduled times.
5. Each SMS includes only the most useful next step, such as a join link, address, confirmation option, ticket link, or event details page.

SMS reminder best practices

1. Get clear consent before texting attendees

Do not send event reminder texts to people who did not agree to receive them.

For U.S. messaging programs, CTIA’s Messaging Principles and Best Practices say message senders should support opt-in mechanisms and send messages only after the consumer has opted in; CTIA also recommends documenting opt-in consent where applicable.

Consent requirements vary by country, region, message type, and use case, so review applicable SMS rules before launching an event reminder program.

2. Keep each reminder short

SMS is not the place for a full agenda. Use email or your event landing page for detailed information.

Use text messages for the one thing attendees need right now:

• Join the webinar
• Confirm the appointment
• View directions
• Open the ticket
• Check the updated room
• Add the event to their calendar

3. Include the event name

People register for multiple events, appointments, webinars, and classes.

“Your event starts soon” is vague.
“[Event Name] starts in 1 hour” is useful.

4. Use one clear call to action

A strong event reminder text asks attendees to do one thing.

Examples:

• Join here: [link]
• Add it to your calendar: [link]
• Reply YES to confirm
• View directions: [link]
• Open your ticket: [link]
• Check updated details: [link]

Avoid sending multiple links or competing instructions in the same SMS.

5. Make opt-out easy

CTIA recommends clear opt-out instructions, including standardized STOP wording, and says senders should recognize normal-language opt-out requests such as stop, end, unsubscribe, cancel, quit, and similar variations.

The FCC has also identified reply words such as “stop,” “quit,” “end,” “revoke,” “opt out,” “cancel,” and “unsubscribe” as reasonable ways for consumers to revoke consent to receive calls or text messages under covered TCPA rules.

6. Do not rely on SMS alone

Texts are easy to miss, delete, or ignore. Calendar reminders are better suited for protecting the attendee’s time in advance. Email is better for richer details. SMS is best for timely nudges.

A strong reminder system uses all three channels intentionally:

Calendar: protect the time
Email: explain the details
SMS: prompt the action

Why calendar reminders should be the foundation

Text reminders can help reduce no-shows when they are timely, useful, and permission-based. But the most reliable reminder strategy starts earlier: get the event onto the attendee’s calendar as soon as they register.

That is where AddEvent fits into the event attendance workflow. AddEvent helps organizers make events easy to save, share, update, and remember across the calendar apps their audience already uses. With an Add to Calendar button, Add to Calendar links, event landing pages, and automation options, attendees can save the event immediately instead of relying on memory or inbox reminders.

Use calendar reminders to protect the time. Use email to provide context. Use SMS to prompt action.

That combination gives attendees the best chance of showing up prepared and on time.

FAQs about event reminder text messages

When should I send event reminder text messages?

Send event reminder text messages when the reminder is timely, useful, and action-oriented. For most events, SMS works best 24 hours before the event and again 1 hour before the event. For virtual events, a final reminder 10–15 minutes before the start time can also be helpful if it includes the join link.

What is the best event reminder schedule?

The best event reminder schedule usually includes a confirmation immediately after registration, a reminder 24 hours before the event, and a final reminder 1 hour before the event. For webinars or virtual events, you may also send a short reminder 10–15 minutes before the event starts. Calendar reminders should be the foundation, with email and SMS used as supporting channels.

How many reminders should I send before an event?

Most events need three to four total reminders across all channels, including the initial confirmation. For SMS specifically, one or two reminders are usually enough. Sending too many text reminders can feel intrusive, so reserve SMS for moments when attendees need to take immediate action.

Are text reminders effective for reducing no-shows?

Text reminders can help reduce no-shows when they are sent at the right time and include a clear next step. Evidence from appointment settings suggests reminders, including SMS reminders, can improve attendance, although the effect depends on the audience, timing, and event type. SMS works best when paired with calendar reminders, not used as the only reminder method.

Why are calendar reminders better than text reminders?

Calendar reminders are built into the attendee’s daily schedule. Once someone adds an event to Google Calendar, Apple Calendar, Outlook, or another calendar app, they can receive reminders based on their own notification preferences. Text messages are helpful, but they are easier to miss, ignore, or delete. That is why the strongest event reminder strategy starts with an Add to Calendar option.

What should an event reminder text include?

An event reminder text should include the event name, date or time, and one clear next step. That next step might be joining the event, viewing directions, opening a ticket, confirming attendance, or checking updated event details. Keep the message short and avoid including too many links or instructions.

What is the difference between an event reminder and an event confirmation?

An event confirmation is sent immediately after someone registers or RSVPs. It confirms that their spot is saved and should include an Add to Calendar link. An event reminder is sent closer to the event to help the attendee remember to show up and take the next step.

Should every event reminder include an Add to Calendar link?

The confirmation message should always include an Add to Calendar link. Later reminders can include the event details page, join link, ticket link, or directions depending on what the attendee needs at that moment. For early reminders, Add to Calendar is useful. For last-minute reminders, the most useful link is usually the join, check-in, or directions link.

How can AddEvent help with event reminders?

AddEvent helps organizers make events easy to save to personal calendars like Google Calendar, Apple Calendar, Outlook, Office 365, Yahoo, and other supported calendar services. By adding an Add to Calendar button, link, landing page, widget, or QR code to your event promotion, you help attendees save the event immediately and rely on their own calendar notifications. Email and SMS reminders can then be layered on top to strengthen attendance.
