We just finished a new feature: Spam Trap. It is meant to reduce, even more, the chances of spam reaching your inbox.
It consists of a hidden input form, that is invisible to the human eye (so the humans leave it empty), but the spam bots will fill it.If that field is filled, our engine will know it is a spam attempt, and will not deliver the email.
If you are trying to legitimately fill a form, and the Spam Trap does not allow you, please let us know (on this thread) and we will solve the problem.
(Spam Trap will be automatically enabled, in the Form Setup page, but you can disable it if you wish)
