Boomerang, the clever service for Gmail that enables you to send messages at specific times and reminds you if you haven’t received a reply to a message you’ve sent, has left beta and developed pricing plans. Boomerang remains free to use for up to 10 messages per month, but personal accounts (for normal Gmail) now cost $4.99 per month and professional accounts (for Google Apps accounts) cost $14.99 per month.follow link
Open Links from Mail in the Background
Tired of switching back and forth between Mail and your Web browser every time you click a link in a TidBITS issue or other email message? Here's an easy workaround. Hold down the Command key when you click links in Mail to open them in your browser without switching away from Mail. That way you can keep reading in Mail and then read all the Web pages you've opened.
