    For your information any application can not use the 100% CPU,and the mail application
    that is not a more MB application so there may be issue with mail application.

    1. So first open the task manager and stop the working of mail apps.

    2. After than remove the mail app from the mac.

    3. Then restart Mac.

    4. Now instal the latest mail app on our Mac.

    5. Then check the again it uses the 100% CPU.

    6. Other wise repair the Mac OS.

    this might be because to the presence of malware in your device

    or may be the mail app got corrupted

    so first of all download a good quality antivirus software

    install it properly and scan your device completely

    destroy all the malwares and corrupt files

    then go to the main menu

    then tap on the settings option

    then tap on application option

    then go to the manage application option

    then select the mail app and uninstall it

    then go to the play store

    download a latest version of the mail app and install it

    make sure that you are using fast internet connection
