Onmutu only requires that the first communication sent by each party is done within the system. For this first correspondence we don't allow any email addresses or page urls to be included in any part of the messages. After the first back and forth correspondence, it is up to each individual if they would like to continue communicating via or messaging system or if they would prefer to share personal contact information and communicate directly.
We do however recommend keeping the correspondence on for as long as possible. This is because if there is ever a review left by a User for a Member and the member decides to dispute the review it is these messages within our system that will be used as the primary source of information for said review.
