Tension Software has announced AutoMailer 2.2.2, an update of its Mac OS X app that allows you to send personalized emails to multiple addresses, in text or web format, each merged with data from an internal database. It’s been optimized for Mac OS X Yosemite.

AutoMailer lets you prepare and  send an unlimited quantity of emails with a single click. Each email can have custom content depending on whom the recipient is. People receiving the emails won’t notice any difference compared to standard emails and they will be able to reply to them as usual, according to the folks at Tension Software.

Version 2.2.2 sports: a better diagnostic for missing server parameters; better error messages in log; and better selection of server port. It also has improved, clearer, connection type names.

AutoMailer 2.2.2 requires Mac OS X 10.9 or higher and costs US$40. You can download it at the Mac App Store or the Tension Software website (www.tensionsoftware.com).
