Eliminating extra vertical space around quotes in letters

Question

Eliminating vertical space around a quote, as described here, succeeds when the documentclass is article

\documentclass[11pt]{article}
\usepackage{quoting}
\quotingsetup{vskip=0pt}

\begin{document}
\noindent We'd like to have 
\begin{quoting}
\emph{no vertical space}
\end{quoting}
around this quote.
\end{document}

but not when it is letter.

\documentclass[11pt]{letter}
\usepackage{quoting}
\quotingsetup{vskip=0pt}

\begin{document}
\begin{letter}{Jack}
\noindent We'd like to have 
\begin{quoting}
\emph{no vertical space}
\end{quoting}
around this quote.
\end{letter}
\end{document}

How to eliminate the vertical space surrounding quotes for documentclass letter?

Answer 1

The letter class uses a non zero \parskip. So you get what you want by removing that added space:

\documentclass[11pt]{letter}
\usepackage{quoting}
\quotingsetup{vskip=-\parskip}

\begin{document}
\begin{letter}{Jack}
\noindent We'd like to have
\begin{quoting}
\emph{no vertical space}
\end{quoting}
around this quote.
\end{letter}
\end{document}
