You can find all email settings by clicking on the 'Settings' menu and then selecting the 'General' submenu.
Q: What if I sent an invoice to a customer with an incorrect email address in their customer file?
A: You will get an error in the top right corner in Billit. Your invoice status will also remain as 'Not sent'. When you open the invoice you can check the email sent status via 'messages'.
Q: I'm getting a notification that the organisation is denying access to the mailserver. What should I do?
A: It is not possible to connect with the mailserver because your organisation is blocking SMTP explicitly for that email address. Contact your IT partner or department to get access.
