Fret not! Here are two possible reasons and how to's so you wont miss receiving test e-mails again.
Test e-mails have landed to Junk / Spam / Clutter folder. Besides checking your Inbox, it will be worthwhile to check from time to time the Junk / Spam / Clutter folder. Chances are that said e-mails were misdirected to that folder.
Test e-mails blocked by your email system. Possibly, your email admin policy may be keeping test e-mails from getting to your mailbox. Ask your email administrator to whitelist the IP addresses for the servers from which the Agility emails are sent: 220.127.116.11 and 18.104.22.168 as well as the email address:email@example.com
If any of the above does not resolve this issue, then please contact the Agility Support via chat or e-mail at firstname.lastname@example.org for assistance.
