              </Group>
        </CommandUIDefinition>
      </CommandUIDefinitions>
      <CommandUIHandlers>
        <CommandUIHandler Command="CustomEmailPageUrl" CommandAction="javascript:alert('Hello, world');" />

Any help would be appreciated.

Hi,
According to your post, my understanding is that you wanted to override the “E-mail a Link” button on the Ribbon.
I had created a simple demo to override the “E-mail a Link” button on the Ribbon, you can have a look at it.
<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
<CustomAction Id="Ribbon.Library.Actions.OverrideEmailLinkButton" Location="CommandUI.Ribbon" RegistrationId="101" RegistrationType="List" Title="Display the UniqueId for the list item.">
<CommandUIExtension>
<CommandUIDefinitions>
<CommandUIDefinition Location="Ribbon.Library.Share.EmailLibraryLink">
<Button Id="Ribbon.Library.Share.EmailLibraryLink.ReplacementButton" Command="ReplacementButtonCommand" Image16by16="http://s10.postimage.org/lhar0oijp/U16.png" Image32by32="http://s17.postimage.org/trf3y2ui3/U32.png" LabelText="Replaced Button" TemplateAlias="o2" />
</CommandUIDefinition>
</CommandUIDefinitions>
<CommandUIHandlers>
<CommandUIHandler Command="ReplacementButtonCommand" CommandAction="javascript:alert('This button has been replaced.');" />
</CommandUIHandlers>
</CommandUIExtension>
</CustomAction>
</Elements>
