Well, I recently upgraded to Tiger from Panther (after HD wipe), then got one of my most needed apps reinstalled: MaxBulk Mailer that is.

I could NOT believe the performance boost this program got from the Tiger upgrade! A colleague had recommended I do so, and I was skeptical because I thought Panther was pretty fast. Well I'm glad I listened, because MaxBulk runs a LOT faster now.

Besides this, overall I recommend MaxBulk because it is the most reliable mass mailer I have found (have tried IntelliMerge, MailDrop, DirectMail etc.)
