Not possible to set up Gmail without kmail To make a long story short, I did as follows to get gmail in merkuro: Create a Clinet ID in https://console.cloud.google.com/apis/ Copied and replaced the generated Client Id and Client secret in the /usr/share/accounts/providers/kde/google.provider file. Added my google account in Online Accounts, available in system settings Installed kmail Configured my gmail account from kmail. Opened Merkuro. It copied the setup in kmail.
