Change font size in envlab?

Question

I am using the envlab environment to create and print address labels. Unfortunately, I have some long names that I am addressing letters to, and not all of them will fit on the label. I'd like to decrease the font size in order to compensate. Does anyone know how to do this? The standard tricks I know (putting \tiny in the beginning of the document, adding 8pt to the options of \documentclass{letter}) don't seem to work.

In this case to be able to use size changes such as \small, they need to be enclosed within a group. So, the second example below with \small Given Name Surname does not produce any size changes, but the third example {\small Given Name Surname} does:

\documentclass{letter}
\usepackage{envlab}
\SetLabel{63mm}{46mm}{10mm}{8mm}{3mm}{3}{6}

\begin{document}
\startlabels

\mlabel{}{%
    Given Name Surname \\
    Address line \\
    postalcode \\
    Country
}   
\mlabel{}{% This \small has no effect
    \small Given Name Surname \\
    Address line \\
    postalcode \\
    Country
}   
\mlabel{}{% This \small has as effect
    {\small Given Name Surname} \\
    Address line \\
    postalcode \\
    Country
}   
\end{document}
