You have sent an e-mail from Carerix. You should have already received a reply, but it does not show in Carerix. How is that possible?
When sending an e-mail, you have 2 options in the field 'from':
Carerix e-mail address from user (firstname.lastname@example.org)
This way the mail will get a sender address like: "<name>@<client>.mail.carerix.net". A reply on this mail will show in Carerix.
It is also possible to let Carerix fetch your personal e-mail so that all e-mails will show in Carerix.
You can find more information about it, on this page.
