1. Start by clicking the cog on the top right corner of the page.
2. From the list that appears, select "Company Settings".
3. On the left side of the page, you'll see an option for "Email Account Settings." Go ahead and click on that.
4. You'll now see two email addresses listed. The first one is the email address for your account. This is where all your invoices, statements, and credit notes need to be sent in order for you to see them in your account.
5. The second email address is for replacement documents. This is where your suppliers will be directed to send replacements when you perform an operation on a document that notifies them. By default, this email address will be the same as the one for your account. But if your suppliers don't send their documents directly to your account, you can change this address by typing a new one in the box and clicking "SAVE".

And that's it! Now you know where to find your account's email address.
