MailMergeApp makes it amazingly simple to create individualized ‘merged’ mailings in plain text format. The single greatest thing about this application is that it uses the Mac OS X Address Book as your contact list, so your mail list is already complete. When you launch the application it asks the Address Book what groups you have configured and allows you to chose them from a popup menu. It does the same with for your ‘send from’ accounts.

All you have to do is type in you message, with spell check and multiple undo’s of course. Insert your dynamic tags such as name, phone number, email address, address, and click generate. MailMergeApp will then build individualized emails in and put them in your out box for you to review. Once you’re sure your mailing is complete. Click send and receive all. Now you users, friends, or family get a specialized email just for them – no more cold carbon copies.

It’s ideal for developers who want to send customized mailings but don’t need the full spam friendly power of the expensive merge programs that are available. It is available through PayPal for $10 , but has a full featured demo mode that allows you to send up to 10 customized emails at a time. Note: There will be a footer added to demo messages stating that this was sent with the demo version of MailMergeApp. Registered versions can send a an unrestricted number of merged emails per batch. Universal Binary (Intel Compatible).

System Requirements:

A Macintosh running a minimum of Mac OS X v10.4.11 up to 10.7. and Address Book. (Both included with OS X). MailMergeApp is not recommended for mailings over 100 persons at a time. Although there are no limits, the desktop email programs sending these messages have a tendency to crash on larger mailings. Breaking them into smaller groups is recommended.

Caution: Before you begin – Backup

The reliability of MailMergeApp is tied to how reliable Apple Address Book and your email client are. Because of this, I don’t recommend mailings to more than 100 people at a time using Apple Mail. There is no limit but Apple Mail seems to start crashing around 100 or so messages. Breaking them into smaller groups in Address Book is recommended.

Create Your Own Plugins:

There is hidden power in MailMergeApp. There is a very simple support for AppleScript plugins. The plugins allow you to customize the email application used and the creation of the messages. There are currently four plugins, one for Apple’s, BareBones’ Mailsmith, Eudora, and Microsoft Entourage, but it can quickly be adapted for your own needs.

To view the current plugins, modify them, or use them to create your own, control-click on the MailMergeApp application and choose show package contents. From there navigate to To add a new plugin just name it whateverYouWant.scpt. Launch MailMergeApp and it will automatically locate your new script.

The script requires two methods. They must exactly match what is below, but from there you can customize to your hearts content. The “on” statements must match the two below:

on sendEmail(theSubject, theBody, theSender, thename, theAddress, theAttachment)


on getSendersNames()
