Millions of people use Gmail. You can send and receive email from your business domain using the “fetch” option. You don’t have to use <name>@gmail.com. You can use <name>@yourdomain.com.
I love Gmail for a lot of reasons. It very effectively deals with all the junk mail I get and it is super easy to search my email archives. I have some email messages from 5 or 6 years ago! On top of that, it’s stable, works across multiple platforms (pc, smartphone, tablet), and it’s free.
If you’re a Gmail user you may not have known that you can search your email messages very easily using a variety of different commands from the Gmail search box (at the top of Gmail). Here are some of my favorites.
Better still, you can combine commands to narrow your search!
For example: is:unread older_than:365d (unread, older than 365 days).
