Motivating people

I’ve been thinking a lot about motivating people recently. What really motivates people to do things? Why do we make the choices we make? How do you convince people to do things when they’re unsure they want to do those things? Let me give you an example. Friends of mine are fostering dogs for local […]

Is your mail being bulk foldered?

Daisy at Signup.to posted a list of 11 things to do when mail is going to the bulk folder. Her suggestions are a good start to troubleshooting and fixing persistent bulk foldering of mail.

Content based filters

Content based filters are incredibly complex and entire books could be written about how they work and what they look at. Of course, by the time the book was written it would be entirely obsolete.
