which edition for error notification

The edition comparison table (SQLBackupAndFTP Features & version comparison) states that all editions can send e-mail. In the free version, however, there is a lock on the corresponding functions.
I would like to know which license I have to buy in order to be able to send me a message in case of error.

Hi Markus_Schebsdat,

To use the notification option with the Free edition, please set up your own SMTP server, here are more details How to send SQL Backup confirmations through my GMail, Hotmail or Yahoo account – SQLBackupAndFTP's blog

To send the notifications with the auto mode please purchase a license with an active Full-Service subscription Why do you need the Full-Service subscription? – SQLBackupAndFTP's blog

If you have any other questions, please let us know.

Thank you!
