For the rest of the month and, maybe through August, I'm gonna get rid of e-mails on my mobile devices - phones, tablets. Every device that I've got and only check e-mail at work via webmail for iCloud and Gmail and on the Macbook Air at home. I think I can save myself quite a bit of space this way.
More and more communications are taking place via texts, group messaging apps like Whatsapp, and social networks like Twitter and Google+. Once in a while, I will get an important e-mail but they are usually not something that requires my immediate attention. A lot of the more interesting ones that I get daily are from Groupon and Livingsocial.
I get notifications about monthly bills and what new comics are out and like the Groupon/Livingsocial e-mails, they can wait.
I do occasionally get a mass e-mail for birthdays and evites. These group of mails, too, do not need me to deal with them right there and then.
In doing so, I avoid a lot of needless distractions while save battery life when no mail is being pushed to me. Also, I'm saving memory space allocated for e-mails and attachments that I don't need right away. And speaking of attachments, there are ways for me to send them without having to use e-mails.
All in all, I don't think I will miss e-mails all that much when I'm on the move. I think for a lot of mobile warriors who do not use their e-mails for work or business, you likely won't miss them much either. I, two to six weeks, I should know if e-mails play the big roles it once did.
