Step 1 of 3
Open the Travelers tab
Your trip's travelers are listed here, with whether each one can get texts.
What the invitation says
By default: "You've been added to [trip] on Sail, a trip planning app." You can write your own message instead. Every invitation ends with how to reply: YES to get trip updates by text, NO to decline, STOP to opt out, or HELP for help.
Traveler privacy
Travelers are hidden from each other by default. In a traveler's settings you can show them to other travelers as first name and last initial instead. They are never shown to the public.
