The web interface lacks the button for sending a document to your email program that you know from the desktop application. This doesn't mean sending from the web is impossible — it depends on which sending method you use.
Sending via an email client on your computer
The envelope button in the desktop application passes the message to the email client installed on your computer. This method is only available in the desktop application — it cannot be used in the web interface.
Sending via an SMTP server
If you set up your own SMTP server in the application, ABRA Flexi sends the emails itself. Sending then also works from the web interface and via the REST API, since it no longer depends on the email client on your computer.
💡 Setting up an SMTP server is also a prerequisite for automatic document sending and for sending payslips.
