# What package or class defines an \email macro?

A colleague sent to me a manuscript written in Ubuntu. I am using Mac OS X Snow Leopard and I only have trouble when I compile the document due to the latex command \email. It seems it is not recognised. What package should I install or what else should I do?

You need to provide the right details to get help (and to write a good question). Could you please provide a minimal working example and the error you get when you compile the document. –  N.N. Jun 15 '11 at 12:11
Try putting \show\email\def\email#1{\relax} before the first occurrence of \email and see if you can now compile, and tell us what Latex tells you about the contents of \email. This isn't a solution but a diagnostic, since it throws away information. –  Charles Stewart Jun 15 '11 at 12:13
moderncv defines \email at least the newer versions of it do... –  Seamus Jul 22 '11 at 10:46

I know that \email is defined in lettre.cls the french version of letter.cls but this macro is perhaps defined in another class or package

-

The AMS document classes (amsart and amsbook) define the \email command.

Extrapolating from your last question, the llncs class has a email macro. In the preamble, use it like this:

\documentclass{llncs}
...
\author{First Author}
\institute{
Example Institute,

@Corentin ??? Read the title of this question, and my answer again. The llncs class provides an \email macro, I mean, it does! –  mafp Dec 20 '12 at 22:57
