In my latest Guardian column, I disclose my five email power-tips — the system I use to manage hundreds of emails every single day:
Sort your inbox by subject
This is my favorite one by far. If something big is going on in the world, chances are lots of people are going to be emailing you about it, and they'll generally use pretty similar subject lines.
When my daughter was born, the majority of congratulatory emails began with the word "Congratulations." When I'd asked my friends to help me find an office, most of the tips I got began with "office."
Best of all, if some spammer manages to get a few hundred copies of a message through my filter and into my inbox, they'll all have the same subject line, making them easy to bulk-select and delete.
Foreign-alphabet spam is also a doddle, since non-Roman characters will all alphabetise at the bottom or top of your inbox; if you don't read Cyrillic, Korean, Hebrew or Simplified Kanji, you can just delete them all with a couple of key presses.
