SMS FROM YOUR MOBILE

Hi Emma, your Product consultation is scheduled tomorrow at 14:30.

Delivered ✓
Calendly supplies the booking context. Your connected mobile sends the customer SMS.

THE DIFFERENCE IS HOW THE SMS IS SENT

Calendly schedules the meeting. Your mobile handles the conversation.

SMSMobileAPI does not require an unfamiliar rented sender for Calendly reminders. Your real mobile phone becomes the SMS gateway, so the appointment message uses the number associated with your business.

  • Send through the SIM card and mobile number already in your phone.
  • Let contacts reply directly to the mobile number that sent the reminder.
  • Use Calendly invitee, event, time and timezone data in each SMS.
  • Keep confirmations, scheduled reminders and failures visible centrally.

SECURE CONNECTION

Connect Calendly without sharing your password.

OAuth is the recommended connection for a customer-facing account. SMSMobileAPI never receives your Calendly password, and access can be revoked from Calendly. Private workspaces can also use an encrypted personal access token.
