BuckyMail sends bulk mail to a large group of recipients and customizes all the personalized fields so that it seems to each individual as though the mail message was typed up just for him or her. The power of BuckyMail is that with one click you can send dozens of personalized messages. This can save you hours of typing. However, it would be impractical to type all the recipients in the TO field every time you send a message. Therefore, you can divide recipients into different groups. It the TO field, simply select the group to which you want to send the message. Then, everyone in that group will receive the message. There is no size limit on the groups. You can add as many recipients as you want in one group (even all of them!) or have just one person if a group if you want.
