How to Fix Emails disappearing not sending : iPhone/iPad

Many iPhone users are facing issue with email disappearing from the iPhone. The emails are missing from iPhone sent box. Even the mails are not received by other users which is very frustrating for the iPhone users. The issue  seems completely random and not happening for every email that is sent to from the iPhone .

The iPhone users are not sure about if the email is really sent or not. The issue is not that emails that have been sent are disappearing, it is that the email actually isn’t sent, and there is not trace of it either way.  The issue is also seen on the iPad app.

The issue is reported by many users to apple but there are no updates from the Apple support on why send emails are missing from the sentbox and not actually sent to the other users. Users are fining this really annoying and losing important data. This seems to be a software bug from apple which needs to be addressed soon to get a permanent fix. Meanwhile please try below possible fix :
