Sorry.. lost in terms of what you are trying to say..
but what about looking at a different approach to mitigate the need for users to have to send you email (and of course delay their completion. Consider what sort of questions your users may want to ask. look at adding in ‘explanation’ fields (maybe a ? asset and under that ‘is clicked’ do a ‘show message’) or even the tooltip function perhaps.
and then if they still need to ask more questions, give them instructions to send you email from their mail client (and then you can take their question to review your form and update by new revision to help future users)
