You can use the manual method or an advanced third-party tool for importing or uploading Google Takeout data to different email services. If you choose the third-party application, then I suggest you to try
Yota Google Takeout Converter. Through this reliable solution, a user doesn’t need any external tools to convert and migrate Google Takeout files. And the best part of the application is that a user can test the working features of the tool by downloading the free DEMO of the tool.
