Hello How can we move the emails from previous hosting company to the new one? If suppose i change my hosting company.. So all my previous emails will be gone from my inbox?
If you have If you have cPanel installed on the server, just do a full backup and restore via WHM and all of your current emails will be migrated alongside with your FTP files and MySQL database. So no your email will stay intact if this is the case.
No, your emails will not be gone. Just ask your provider to move full cPanel for you, and it will move all your data from that cPanel.
