For email and word processing, it depends on what you've previously used. I would say that LibreOffice is quite all right for word processing. Also have a look at FreeOffice (https://www.freeoffice.com/en/ https://www.freeoffice.com/en/) which aims for great compatibility with MS Office. For an email client, I personally use the GMail web client nowadays, but I've used Thunderbird for a long time and it's fine (not as polished and good looking as Mail.app on MacOS though).
