Sorry about that. I tried it and received the email. I investigated a bit and see it sent you 4 emails, but they were all blocked by your email server because it uses a service called Spamhaus which has listed the email service we use to send emails as spam. I've contacted our email service to get it resolved.
We'll be removing the email requirement for the Spine trial soon. Until then you can open your Spine prefs.json file, found here:
Spine Troubleshooting: User files
You can open it with a text editor and add trial:1, to the beginning. For example, the file likely starts with:
{version:
Change it to:
{trial:1,version:
Then the trial will not prompt for your email address.
Sorry for the trouble!
