Tension Software (http://www.tensionsoftware.com) has updated AutoMailer, a Mac OS X app that lets you merge data from a database with email templates and send to multiple addresses in text or web format, to version 2.0.1. The upgrade adds the ability to send both text emails or web (created in html) emails and management of an Except (never send) list and possibility to send directly via an external mail server.
AutoMailer lets you send an unlimited quantity of emails with a single click, with personalized contents for each recipient. Emails sent by AutoEmailer look like and are standard emails.
AutoMailer 2.0.1 requires Mac OS X 10.8 or higher. It costs US$25 and is available at the Tension Software web site and the Mac App Store.
