$0.414 for First Class bulk mail
$0.273 for Standard bulk mail
$0.19 for Non-Profit bulk mail
The good news is that the First class bulk mail rate is expected to remain the same. And postage rate increases for standard bulk mail aren't expected to be huge (perhaps just a few percentage points) but savings are savings so if you've been planning to do a magnet mailer now is a great time to get started.
