Merge Tools Add-In (for MS Word)
Merge Tools is an MS Office Add-In for sending bulk/merge (e-)mails with attachments. It comes as a simple Word-file with a macro, to be placed in <…\AppData\Roaming\Microsoft\Word\STARTUP>. Starting with the built-in Word functionality for merge mails, you can setup and prepare the dispatch before finishing it with the add-in buttons, shown in a dedicated ribbon.
