Switch from Hancom Mail to eM Client

In your Hancom Mail app, go to Menu > File > Export.

Select Export settings to .xml files and click Next.

In the next steps select which part of the Hancom Mail settings you want to keep and choose a destination file for your settings file. Click Finish.
Once the files are exported, you will get a notification.

Note: If you have any local data stored in Local folders, you can follow the same steps just select export of messages into EML files, contacts into VCF and any other data that is not synchronized with your account.

Next step is to download and install eM Client.

Open the downloaded setup file and proceed with the installation steps.

Once eM Client it opened, skip the initial setup
and go to Menu > File > Import.

Scroll down to import eM Client settings (.xml), select the file you exported from Hancom and follow the import steps.

You're all set!

You can now use your email accounts and other settings in eM Client, the same way it was in Hancom Mail app.

Note: The import options can be accessed at any time later via Menu > File > Import, so if you exported any other data in the previous step, you can repeat it for your messages in .eml files, contacts in .vcf, etc.
