I was doing things around emails and found myself a question I could not answer: what is the attribute "Is_Test_Email" in System entity Sent_Email used for?

Platform documentation does not give any light, nor did forum searches. I tried sending few emails, but there doesn't seem to be a way to change this flag status from code, design or runtime.

Only thing I could figure out that this boolean property could be related to these settings found from Service Center > Administration > emails:

I shouldn't change these settings just to test some stuff out, so the question is - is my guess correct or not?

Hi :),

It seems to be some boolean that we can put with the value true, when we are testing the emails. And after when we are filter the emails this flag can be used to prevent the test mails from appearing.

Best Regards,
