What is a "group mail"?

If you are a ProZ.com member you can send 'group mails' to up to 100 colleagues.

To do so, search the directory, http://www.proz.com/translator-directory/ to select a group that meets certain parameters (for example, language pair, credentials, areas of expertise, etc.) Select the check boxes to the left of the translators in your search results who you wish to contact. Then click the "Mail all now" link at the bottom of the page. Your message will be sent to up to 100 people who met your criteria.

You can imagine many uses for this: finding someone to help you on a project, starting a team, etc. This feature is not to be used for advertising your own services, however.

You can restrict who is allowed to send you mail through your profile, or disable profile mailing altogether. See the email preferences FAQ for more information.
