Every time you receive or send an email to a new contact, the Mail app saves this contact’s email address as a “recent” or “other” address somewhere so that if you ever want to email this person again, you can start typing his email address, and the Mail app will offer some autocomplete suggestions.
In some instances, this is a great feature. For example, you might not have saved the contact info of this person who emailed you 3 months ago, but if you remember his name, you can start typing it, and the Mail app will automatically suggest his email address, based on your recent communication with him. That’s the benefit of the feature.
The downside of this recent emails feature though is that it might save email addresses from people you don’t care about. Worse, it might save old email addresses that aren’t being used anymore, sometimes offering these old addresses as a top suggestion.
I recently experienced this problem. I updated the email address of one of my contacts, making sure I deleted her previous email address. Now every time I start typing her name in the “To:” field of the Mail app, it suggests both her new and old email address.
In this post, I will show you how to remove recent and other email addresses from the recipient field autofill in the Mail app for iPhone, iPad, and iPod touch.
