Hey everyone.
First of all, thanks for all the answers!
I know it’s been quite a while since I posted this topic, but I did implemented the formspree form and I does work perfectly. It does suck that my client need to confirm his email, but most of the times I am the one who does this for them.
Anyway. Thanks for the help!
ps: my english kind of sucks, but I think you guys can understand. =)
