If you are using Evernote, then you can now sync your notebooks in Evernote with Gmail. Using EvImSync, freeware portable too, notes in Evernote are uploaded to your Gmail account as emails, and emails in Gmail are imported to Evernote notebooks as notes. EvImSync uses the Evernote script engine
ENScript.exe to import and export notes. These notes are parsed and then compared to emails in your Gmail account using the IMAP protocol. So you basically need to gave IMAP enabled in your Gmail account.
You can sync one notebook with one folder in a Gmail account. EvImSync allows you to sync as many notebooks and Gmail folders as you like. Although the service looks nice, there are limitations for the tool like deletion are not reflected in sync, moreover if you have tagged any email, then these changes are also not synced.
By default, EvImSync stores its configuration files in the
%APPDATA% folder. But you can also use EvImSync on an USB-stick, to do that you need to rename the exe file to
EvImSyncPortable.exe: this will force EvImSync to store its configuration in the same directory as it was started from.
