We opened the mobile phone desktop and found that there was nail software on it.

After entering the nailing interface, we can click on the company homepage.

Then enter the main page of the company, and we can choose to nail the mail.

Then, after entering the interface of nailing email, we click the settings in the upper right corner.

After entering the settings, we can click to select the email signature.

Then in the email signature interface, we just need to write it in our personal signature.
