Yes you can!
If you want to use your own email server for the delivery of SkyPrep emails, just let us know at firstname.lastname@example.org. You will also need to provide us with the SMTP details for your email server, including the login information.
Once it has been configured, all emails will be sent from your server instead of ours. However, if you decide to go this route, please note that the Email History feature will no longer work.
