Use Hidden input in Mail tag

Hi,

I would like to pass dynamic client email addresses from a hidden input into the To: field for a Contact Form 7 form.

But according to documentation on config errors, only an “email*” Mail Tag can be passed into the To field.

Wouldn’t this be somewhat of a security concern, since the client e-mail could be modified as an email tag? I’d prefer to keep it hidden.

If I don’t use this configuration, I will have to create hundreds of forms with different To: recipients, which seems very counter-intuitive.

Any suggestions for a way on how to include hidden input values in the To: field?

Thanks for your time and help.

Sincerely,

Blaine
