Mail Merge Toolkit works to extend the abilities of mixing and joining in MS Outlook, Word and Publisher programs. You can insert data fields in the area of "subject", add attached data and send emails in GIF, HTML, RTF and text formats.Thus, using GIF messages for example, you can be sure the receiver can see them whatever the messaging client or program they use. Mail Merge Toolkit also gives you more control over the process of sending emails, and an option to stop or abort email sending at any moment.
