How to divide addresses across a business.
THE USUAL SET
info@ or hello@ for general enquiries sales@ for new business support@ or help@ for existing customers accounts@ or billing@ for invoices and payments careers@ or jobs@ if you recruit
WHY THESE AND NOT MORE
Every address is something to monitor. Five that are checked beat fifteen that are not.
MAILBOX OR FORWARDER
Use a mailbox where several people handle the address and need to see what each other has done. Use a forwarder where one person handles it and replies from their own address is acceptable.
For sales and support, a shared mailbox over IMAP is usually right.
PUBLISHING THEM
Put the right address in the right place: support@ in your help pages, sales@ on your product pages, accounts@ on your invoices.
A single info@ for everything means someone sorts everything by hand.
AS YOU GROW
Departmental addresses scale where personal addresses do not. A customer who has support@ keeps working when staff change.
