I remember a time in university when I used to love receiving email. I actually read email ads and signed up for email newsletters.
Not anymore.. With about half my day spent in analyzing and answering emails, I am no longer a fan of it anymore, to say the least.
A consequence of too much email is that I now love short emails with all my heart. Email courtesies are nice but being able to understand and respond to your email within 5mins is even nicer.
Cut to the chase people- keep emails short and sweet!
