I have imported contacts and they show up but when I try to address a message, there are no contacts.

Have you tried entering some text in the “To” field? It should then gradually narrow down the list, based on what you type.

Open one of these contacts in eM Client and make sure it has an email address in the email address field, or that the email address is in a valid format.

Thanks, problem solved.
