SuperMerge

SuperMerge is a Plug-In (or Add-In) for Microsoft Word. Use it to create a mail merge with addresses from MS Outlook contact folders.

If you want the mail merge to be sent only to specific recipients, you don't have to move Contacts to another folder or
write queries.
The selected addresses can be saved in a separate Set, so you can re-use your selection later on. With the SmartSend option on SuperMerge looks for e-mail and fax addresses. If found, it creates an e-mail or fax instead of a letter in Word.
