Avoid unloading your inbox first thing on Monday morning. If you really want someone to pay close attention to an e-mail you are sending them, try sending it on Tuesday afternoon or Wednesday mid-day when their inbox {and yours} is less inundated. Plus, there is nothing worse than sitting down to 50-100 e-mails in your own inbox, why would you want to contribute to doing that to others?

So it's not entirely work related, but it is definitely a chore. I try to avoid going to the grocery store on Mondays, or running any of my other errands as much as possible. I avoid the gym, the dry cleaners and pretty much any place that has a parking lot {ha!}. It's always too crowded and can serve as a nice big distraction to completing bigger picture goals for keeping your life on track. 

Stop doing the same tasks over and over again and come up with a more automative system. I did this recently for the way that I manage all of my incoming inquiries and it genuinely made the biggest difference in my e-mail inbox.
