Back from a 2 week holiday, inbox says 100+ messages

What is your back 2 work routine to get the current project status?

Go through the mails in correct temporal order, deleting or moving all unimportant ones or predecessors on follow-ups immediately. But do not answer or start working on one until you are through.

After that the number of mails should be reduced severely and you will a have a first overview.

Then it's time to take a closer look and get rid of all small tasks, where just a quick response or less than five minutes of work is necessary.
