Overview
No-shows to Zoom meetings cost small businesses thousands of hours per year — especially for sales calls, discovery calls, and client check-ins. Automated reminders sent 24 hours and 1 hour before dramatically reduce no-show rates. Using Zapier with Calendly or Google Calendar as the trigger, reminders can include the Zoom link, agenda, and any prep instructions — giving participants everything they need to join prepared and on time.
Before you start
- Zoom account with meeting links
- Google Calendar or Calendly for meeting scheduling
- Zapier Starter plan (for Delay step)
- Twilio account for SMS (optional)
Step-by-step guide (4 steps)
Connect your calendar to Zapier
In Zapier, create a Zap with Google Calendar trigger 'Event Start' (set to fire 24 hours before). Or if you use Calendly, trigger on 'Invitee Created' and use a Delay step for timing. Connect your calendar and test with an upcoming event.
Send the 24-hour email reminder
Add Gmail as the action: 'Send Email'. Address to the meeting participant's email from the calendar event. Subject: 'Reminder: Our Zoom call is tomorrow at [Time]'. Body: 'Hi [Name], just a reminder that we have a Zoom call tomorrow at [Time] [Timezone]. Zoom link: [Meeting URL]. Agenda: [list items]. See you then!'
Extract the Zoom meeting link from the calendar event description using a Zapier Formatter step. Most Zoom-integrated calendars include the link in the event body.
Send the 1-hour SMS reminder via Twilio
Create a second Zap (or use a second path in the same Zap) triggered 1 hour before the meeting. Add Twilio as the action: 'Send SMS'. Message: 'Hi [Name] — quick reminder: our Zoom call starts in 1 hour at [Time]. Join here: [Zoom link].'
SMS has a 98% open rate vs. 20% for email. The 1-hour SMS is your most impactful reminder — don't skip it for high-value calls.
Add a prep email for discovery or sales calls
For first-time calls, add a 48-hour prep email: 'To make the most of our time together, here are 3 questions I'd love you to think about before we chat: [Question 1, 2, 3].' Prepared clients lead to more productive meetings and faster sales cycles.
What you'll get
No-show rate drops by 30-50% with a 1-hour SMS reminder
Participants arrive with the correct link — no last-minute scrambling
Prep emails improve meeting quality and client readiness
Runs automatically — no manual reminder sending needed
Common mistakes to avoid
Only sending email reminders and skipping SMS — SMS dramatically outperforms email for day-of reminders
Not including the Zoom link in every reminder — participants lose the original invite
Sending reminders too far in advance (days before) without a same-day nudge
Not personalizing reminders with the participant's name — feels like spam
