Ability to confirm a candidate by recruiter with an invalid email address

Summary

We need to have a functionality where the recruiters can confirm a candidate's job application even in the candidate has no valid email address.

Currently, we have no functionality in Oracle by which the recruiters can confirm a candidate's job 
application if the candidate has an invalid email address.
We have recruiting in various countries where hourly workers do not have ready access to a computer 
or they apply through different local sites vs our website as this is standard local practice.
We need the ability for recruiters to document these applicants in ORC without the candidate taking action.
