Autoresponders should be an indispensable part of email boxes in any bigger firm or a prosperous company. It is a kind of program that generate special messages informing people who sent any letter for firm’s email box that their mail was received and will be examined as soon as possible. It is a useful option because clients send mails even when nobody from the company is working, for example on Saturday or Sunday – we are talking especially about people who are responsible for writing back for customers. Autoresponders are sent automatically – the worker must prepare only a certain content that will inform clients that the message has reached it recipient but it will take some time to answer it and that he should not be worried. People, we are talking now about clients, seem to not be aware of the fact that other people also need some rest and they cannot be available twenty four hours for seven days in the week. Autoresponders help to remind them about that regularity in a proper and nice way without offending anybody.
