Move or Delete Emails in Bulk on an iPhone
To relocate or remove several emails at once from an iPhone, select the messages then choose what to do with them.
Delete Every Email in a Folder
You can delete every email in a folder if don’t want to spend time selecting each of them. However, not all iOS versions support this, and neither do all email folders. The best way to remove all emails from a folder is to log in to the email provider’s website and do it there. Another option is to connect your email to an email client on your computer, then empty the folders.
Move or Delete Email Automatically
Delete or move emails automatically if you find yourself managing messages from the same sender each time you get them. For example, to move an email from your brother into a Family folder or your online purchase confirmations into a Receipts folder. To automatically manage emails, use email filters and rules, which the iOS Mail app doesn’t support. However, some email providers do, in which case you can set up the email filters from a web browser through the webmail service. As long as you use IMAP on your iPhone to access the emails, the filters will apply on your phone, too. The technique for setting up email rules is different for each email provider, but it’s usually self-explanatory. For example, creating email rules in Gmail isn’t the same as filtering emails in Yahoo Mail.
