One suggestion is to consider having more than one email for the purposes of separating emails from people who email you about personal things and people who email you about work things. This may be useful in addition to the suggestion in OP to have a separate email for subscriptions/mailing lists.

This has been useful to me in the past for being able to effectively segment my 'work life' while on holidays or taking a break without missing out on social updates and emails from friends and family members. Aslo, when I am on holidays in non-urban environments I frequently don't have the spare bandwidth to download all my work emails to my desktop client as easily as at home.

I suggest conssidering this methodology to delineate a nice, clean mental 'break' and to avoid the temptations of 'just glancing' at work-related emails that come from having a general email address.
