I am very thankful to people who take the time to share their tips for email management or other such tasks in enough detail that others can implement.
A lot of people have absolutely no strategy for managing email. A simple blog post like this could seriously benefit someone's life.
I've been using this strategy for the last 3 years, and I've found it super effective. It completely removed the need of "advanced" mail apps with features like "snooze", "reminders", etc.
