Send mail from splunk free license

[kmuppana]

Is it possible to send mail notification from Splunk Free Edition using custom REST point?

[yannK]

Splunk free has no search scheduling therefore no alerting.

You can test if it can send email form a search, with the search command |sendmail
and build your own scheduler, with the CLI and cron/OS scheduler.

Not mentioning that you can also pay for Splunk Enterprise...
