      Whitelisting in Mimecast

      Whitelisting is an important step in the process of sending out phishing-simulations. It prevents mail from being stopped by your spam/anti-phishing filters and makes sure that the mail reaches your users.  

      We have provided a step-to-step guide on how to whitelist CyberPilot in Mimecast. Follow the steps below to allow CyberPilot, on your behalf, to send emails that appear to come from an email address at your domain. 

      When the whitelisting is done remember to let your dedicated Customer Succes Manager at CyberPilot know. After we will send you a test-mail. Make sure to check if the email goes through. If there are any problems or additional questions, write to us at:  support@cyberpilot.io
