I was hipped to Unroll.me
by cartoonist Box Brown
this week and successfully unsubscribed from every email list I didn't want to be on in two minutes. It feels great. I was just deleting them all every day for years, which has probably translated to months of my life spent getting rid of emails I never signed up for in the first place.
One thing I've noticed over the years is that when I'd pitch my work to certain media outlets, I'd suddenly find myself on their mailing lists. I guess it's a passive form of rejection.
