Try removing yourself for awhile (you can always rejoin). You'll save time and money and you're bringing less into your home. Still reluctant? Think to yourself -- Would I be shopping for X, Y and Z if they were full price? Would I voluntarily visit that site today if it hadn't been for the email? Do I need any new clothes/shoes/housewares? Say, "No!" email list - Don't sign up for these emails in the first place.
You can uncheck the box or update your preferences so you don't receive marketing emails (special offers). If you start to waiver, remember that refusing the emails now will save you time later. Feel guilty? You can still support a group, cause or charity even though you don't receive their emails anymore. Decide to Delete -- Even though you unsubscribed from companies, people will always send you emails you're not quite interested in and you don't have time for
-- forwards, photos, jokes, etc. See who they're from, check the subject and even open it. Once you see it's a time waster, DELETE it right away. Do it right then! Never leave an email thinking you'll delete it later. There are many companies that send daily emails, like recipes or articles of the day.
