If you need to know how to import Apple Mail into your Gmail account? Then I recommend utilizing the third-party tool, that solves all problems with Apple Mail to Gmail account conversion. The eSoftTools MBOX Converter software is the most useful software for all email clients that support mbox file formats, like OperaMail, PocoMail, SeaMonkey, Eudora, AppleMail, etc. The software can easily export single or bulk mbox files to other formats at once without facing any problems. It can also show the Live Preview choice before beginning the migration process. The free trial is given to all users for their comfort.
