About the Program

- Message frequency: varies with your meeting activity.
- Cost: message and data rates may apply per your carrier plan.
How Account Holders Opt In
TimeBlox account holders enable SMS/RCS messaging inside the TimeBlox portal (portal.timeblox.ai, sign-in required) by adding their mobile number to their profile and expressly agreeing to receive messages. Providing a phone number is optional and is not a condition of using TimeBlox. The opt-in step presented in the portal:
Phone Number
Consent is not required to use TimeBlox, and account holders can remove their number or withdraw consent in the portal at any time.
Messages to Meeting Invitees
When a TimeBlox account holder schedules a meeting, they may provide a participant's phone number so the assistant can coordinate directly with that participant. In that case:
- The account holder represents and warrants that they have the participant's consent to be contacted by or on behalf of TimeBlox.
- The first message a participant receives includes “Reply STOP to opt out”, and every STOP is honored immediately and permanently unless the participant re-subscribes.
- Messages to participants are strictly limited to coordinating the meeting they were invited to — never marketing.
Example Messages
- “Hi! Eric would like to schedule a 30-minute meeting with you this week. What times work for you? Reply STOP to opt out.”
- “Your meeting with Eric is booked for Tue, Aug 11 at 2:00 PM PT.”
- “Reminder: you haven't shared your availability for ‘Project sync’ yet — any times that work this week?”
Opting Out and Getting Help
- STOP: reply STOP to any message to opt out. You will receive a single confirmation and no further messages unless you re-subscribe by replying START.
- HELP: reply HELP to any message, or contact support@timeblox.ai.
- Supported carriers include AT&T, Verizon, T-Mobile, and others. Carriers are not liable for delayed or undelivered messages.
