The SmarterMail limits are set on the number of mailboxes you require for your installation.  You can quickly and easily upgrade these limits at any time by purchasing one of our upgrade packages.

Simply select your existing license and the license level you wish to move to from the drop downs above; we will also need your existing SamrterMail license key.

Once yuor license has been upgraded you simply need to re-activate your SmarterMail license from your admin area and the new limits and/or version will automatically become live!
