E-mails are sent by default from an noreply@akti.com address, which means that customers can't reply to these e-mails. If you wish to do so anyway, you can configure what the reply email address is. When the customer clicks on "reply" in his mailing tool, this e-mail address will be displayed. You can set this reply e-mail address from the 
Settings of the specific modules, under the advanced settings. Here is an example for the Invoicing module:
- Go to the Invoicing module.
- Go to Settings Invoices and select the Advanced settings.
- Open the submenu "Default Email" and fill in the required fields (*).
You must repeat this action for each module from which you will send documents!
