Boomerang 1.0 for Gmail Adds Pricing Plans
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.
