From the error message it seems that courier cannot detect the macro alias, based on your macro tags in the template

could you post the macro mark-up from the template Global Textpage?

Per,

I managed to get a bit more info by looking at the DataResolvers source. The error should also include the alias of the macro. I added an alias to all the macro's in the template and it turns out Courier chockes on the first macro, which is  a simple inline razor script:

<umbraco:Macro Alias="inline1"  runat="server" language="cshtml">
        @if (Model.Media("menuImage","umbracoFile") != null) {
        <img class="navimage" src='@Model.Media("menuImage","umbracoFile")' alt="@Model.Name" />
        }
    </umbraco:Macro>

I'm having the same issue too. This is a known issue since I started using Courier 2.1.1 and Umbraco 4.7.0. I didn't get chance to report it as a bug until now.

Similar errors reported from log.txt file:

I'm using the <umbraco:macro> server control tags to embed C# Razor code inside my EosJobList.master file:

<umbraco:macro language="cshtml" runat="server">

@* Do something here. *@

</umbraco:macro>

Thanks for reporting it, will make sure to get this fixed for the next release
