If you request email confirmation and the lead doesn't click the confirmation link is not possible to even see this lead data despite that it was inserted in the form by the lead.
It would be fine to be able to see this info and even resend a confirmation email.
The second confirmation email could be sent manually or in a lapse of time:
"Resend confirmation email in 2 days", for example.
It could be fine, as well if this second email could be chosen to be the same or different from the first one.
I think this could be a very good improvement while it will allow to reengage leads that will be lost other way.
