Just in time for the holidays, this Gmail plugin allows you to turn emails into physical greeting cards. Google Chrome extension Dear Inbox is available for free and gives users the ability to send printed greeting cards right from their inbox on Gmail.
The standard compose button will have a button beside it that opens the Dear Inbox menu. This menu allows people to pick from a variety of seasonal categories and different card designs they can customize with personal details. The body of the email consists of a personal message users write and drafts are automatically saved. Designed to look like regular email composition, the Gmail plugin interface requires you to enter a mailing address in the recipient field rather than an email.
