How to avoid hotmail and gmail users when they try to use cf7??
I ask this because when you collect their email, after is very difficult to send them any newsletter because usually they go directly in the spam folder.
So having seen that with other isp there is no problem, it's better to avoid to collect these useless emails.
We have used the same approach in another .asp site and works very well (mean no loss of users, interestend people used others email isp)
Thanks.
