Hi

I have tried many email marketing services for this website http://besthairextensionsnearme.com/. But the problem remained the same that thrive optin form directed to the url of that email marketing service. Now i just have seen the problem i am facing here too. So just signed up with Mautic and now i will see what will happen. Will let you know.

Hi

Kindly reply urgently as I have done everything but the simple manual code is not generating fields. thrive option doesn’t work with plain html.
