For non-scripting testers, it is hard to create a script to send the log file via email to one or multiple email addresses.
To make this easier, implement feature "Send log to email", which can be used from in Keyword Driven testing, something like this:
when dragging the operation "Send log to email address" to your active Keyword test, a wizard will be invoked in which you can supply smtp address, from address, to address, subject, body, smtp port number, servercredentials, and if you want to include Visualizer images., to configure the email send routine. If possible, multiple standard email servers can be included (gmail, outlook.com, hotmail.com, etc)
Then when test is executed and the operation "Send log to email address" the email is sent to specified address.
