According to our research, the majority of iPhone users check, send, and receive emails on their devices. As time goes by, you may have lots of emails in your inbox.

The spam email refers to unsolicited email messages. They are usually sent in bulk to a large list of recipients from brands and organizations. Some spam emails also include phishing links and viruses. While the Apple Mail app includes the Junk folder, which stores the spam emails on your iPhone, it cannot identify most spam emails. As a result, you need a powerful email eraser application, such as Apeaksoft iPhone Eraser. It can help you to get rid of spam emails on your iPhone.

How to Delete Spam Emails on Your iPhone

Step 1. Connect to your iPhone

Download and install the best email-erasing software on your computer, and open it. Next, connect your iPhone to your computer with a Lightning cable. Then the software will recognize your device immediately.

Step 2. Choose a level

There are three erasing levels:

Low level overwrites your spam emails once with higher speed.

Middle level overwrites your spam emails twice to make sure they are unrecoverable.

High level overwrites your emails thrice to completely get rid of spam emails.

Choose an appropriate erasing level depending on your condition.

Step 3. Delete spam emails

Once you are ready, click the Start button. Then input 0000 into the field, and click on the Erase button to begin erasing all emails on your iPhone along with other data and settings.
