Calendar invites by phone number — a transactional SMS service.
Visit maeil ↗maeil, operated by CB Industries, LLC, sends transactional calendar invitations by SMS — never marketing or promotional texts. When an event organizer adds a person's US mobile number as a calendar guest, that person receives one invitation text with the event details and a one-tap link to accept or decline, plus at most one RSVP confirmation for the same event. Organizers confirm they have the recipient's prior permission to be contacted about scheduling, in compliance with the TCPA.
Message frequency is low — about one invitation per event plus at most one confirmation. Message and data rates may apply. Recipients can reply STOP at any time to opt out, or HELP for help (or email operations@cb-industries.co). Mobile numbers are never sold or shared with third parties or affiliates for marketing.
Our opt-in is organizer-initiated and attested — the organizer confirms they have the recipient's prior express permission. The full opt-in flow, the exact message wording, and screenshots are public at maeil.cc/sms-opt-in.
