Email Etiquette Tips
We've been using email for about 20 years now, but many of us still don't get how to use it.
If someone sends an email to multiple people don't for the love of God hit reply all when sending your reply. No one else cares about your reply. Just reply to the original sender.
If you're sending an attachment, link it to the email right away to avoid sending the email without the most important part.
Nothing is worse than getting an email with something you have to act on immediately, and finding the attachment isn't there, and then you can't get a hold of the person that sent it because they have moved on to the next point in their day.
Keep work emails formal and personal emails informal.
