About Spam

Some people have received emails that appear to come from us but that we did not write. This is because anyone can fake the Sender address of an email. It is known as Joe Jobbing and there is not much that we can do to prevent it.

To verify that an email is legit:

  • Verify that the Sender address is one of those listed here.
  • Verify that the signature of the email contains the exact name of our product and company: CSHTML5 and/or USERWARE.
  • If you are still unsure, the only way to be 100% sure is to read the SPF information that is contained in the email headers. To learn how to do that, please read this page, including its 'Sender Policy Framework' paragraph.

If you are still unsure whether an email is legit or not, please be sure to NOT open any attachments, and contact us here.
