Uploading malware samples - by email or CAVS

Lately I uploaded many malware samples undetected by CAVS. I used option in CIS “Submit suspicious file”, but I wonder if would be better to send these samples via email to malwaresubmit@avlab.comodo.com. Is there any difference?After all both ways should be ok.

Submitting by email (the one you suggested) and CIMA are the two fastest ways.
