E-MAIL POLICY

The following is [Company’s Name]’s policy on the use of internal e-mail:

all employees with e-mail should check their electronic mailbox (as well as their physical mailbox) at least once daily, preferable in the morning.
the e-mail system is intended for reminders (i.e. just reminding you about making the phone call we discussed yesterday…) and the exchange of non-urgent information such as FYls (i.e. did you hear about the new cable Belden introduced…)
it will also be used for interoffice memos regarding company-related topics such as meetings, procedures, social events, general information and other types of information that can wait 24 hours or more before being read. Generally speaking it will not be relied on for breaking project news except in a reminder or supplemental capacity.
it is not meant to for requests for decisions or urgently needed information especially as they relate to project work (i.e. should I send a ream of paper with the printer being shipped tomorrow or hold them for…; please let me know if you’ve revised the document for the client as printing has begun…; etc.)
requested information should only be sent via e-mail if specifically requested and even then you should verbally let the person know that you’ve sent them the information.
