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.

  • 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. Jun 15, 2011 at 12:13
  • moderncv defines \email at least the newer versions of it do...

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


Very Simple Solution

All you need is just define \email in your preamble as follows

\newcommand*{\email}[1]{\href{mailto:#1}{\nolinkurl{#1}} } 

which defines your desired email format: monofont space, hyperlink to mail directly. you can then use the command \email, for example:

\email{[email protected]}

N.B. Sometimes \email command is reserved in the class you using for any reason, you can change it to anything else, e.g. \emailf, \emaill, ... etc.


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:

\author{First Author}
  Example Institute,
  Example Road 12,
  \email{[email protected]}

Actually, all the macro does is to set the email address in a typewriter font.

  • @Corentin ??? Read the title of this question, and my answer again. The llncs class provides an \email macro, I mean, it does!

  • Sorry for the unfriendly, automatic message from the review tools... What I meant to say was that your answer looked more like a comment in the present form. Perhaps supplementing it with a MWE would turn it into a valuable answer (but this also applies to the original question which is a bit vague in my humble opinion)
