How to read Apple's SMS tag?

In the iphone6 version of ios6, every time you receive an email, a number will be added to the unread email to remind you how many emails you haven't checked. There are often a lot of useless spam in these emails. I don't want to check them one by one, but if I don't check them, the number of unread emails will not change, which may affect the inspection of important emails.

The specific method comprises the following steps:

1. Click to enter information on the iPhone interface.

2. Click the Edit button in the upper left corner.

3. Click the "Read" button in the lower left corner.

It's over when it's over. I hope you like it.
