If you are not receiving collaboration invites from InVision, it’s possible that your email server has rejected our incoming emails. When this happens, we automatically stop sending emails to that address. If you are experiencing this issue, please contact InVision support to have your email address reactivated.
Note: The only way to permanently resolve this issue is to prevent your email server from rejecting our emails. If you continue to experience problems after we have reactivated your email address, we recommend contacting your email administrator. The solution might include whitelisting emails sent from invisionapp.com, or it could include further action from your email administrator.
