The unsend feature is useful if you have accidentally sent an email to someone or have sent an angry email to Netflix over the cancellation of another of your favorite shows, only to realize that there is no point in complaining because no one will read your emotional message in the first place.
Aside from the problems you can prevent by recalling an email, the Mail app will also let you know if you forget to include an attachment or other “important part of your message.” In addition to that, Apple will also add a Remind Later feature to let you “resurface a message at any date and time” and a Follow Up option which will automatically remind you to follow up on an email. You will be able to schedule emails ahead of time as well, preventing you from forgetting to send an important email at a specific moment.
Furthermore, with iOS 16, Mail will also receive “the biggest overhaul” to its search feature. Apple said that it has incorporated “state-of-the-art techniques” to show you “more relevant, accurate, and complete results.” With the upgraded search feature, you will easily find recent emails, contacts, documents, and links. As Apple stated, you will see what you are looking for the moment you begin to search for emails.
