The trust level of individual senders and recipients is indicated in IncaMail with up to three stars. The stars illustrate to what extent the user’s identity has been checked.
| Stars | Trust level | Possible identity checks |
| (none) | Unknown | None, status hidden |
| * | Good | Registration, verified data acquisition or similar |
| ** | Very good | Postal address verification, contract or similar |
| *** | Excellent |
Personal identification, passport/ID, SuisseID or similar Yellow ID is needed |
You have the option of hiding your own trust level in the settings. Users with a hidden trust level receive no information concerning the trust level of their communication partner.
