[Koha] check out time emails

[Hira Akram]

Hi All,
Are there any settings for email notifications at check in / check out / suggestions management time other than the settings that we do for every patron category??
I am trying to send emails from my KOHA at circulations time but no email is being sent but I am able to send and receive email from serial claim module. Can anyone help What might be reason for this issue??

Kind regards,
Hira Akram
