This is some information from a site called http://bulkmail.info/
"There are various levels of savings depending on how much how much of the postal service's work you are willing to do.
...if you are a nonprofit organization and have received approval from the USPS to mail at nonprofit rates. The nonprofit rate for the same piece of mail using Standard Class would range from 13.1Ã‚Â¢ to 17.0Ã‚Â¢.
Whether it's worth it for you to do the extra work to get to the next level of discount depends a lot on how many pieces you are mailing. For mailings of many thousands of pieces, you probably want to save as much on each piece as possible. For smaller mailings, the cost for additional software or the time you would spend on more complicated preparation is often not worth the few extra pennies saved.
For example, adding barcodes to your addresses would save you about 5Ã‚Â¢ on the piece discussed above (less for nonprofit mailers). To add barcodes, you must have a perfect 9-digit zip code for every address. To do that, you either need to buy expensive software to verify your zip codes, or you need to send your list to an online zip code service. Either way, you quickly eat up the extra savings unless you are mailing thousands of pieces."
The PF has not done any major mailings to date because we have such a strong internet presence so the need for a nonprofit bulk mailing rate has not been as strong, though I know it is something we are looking into now that we are getting bigger. In my experience, you have to have at least 500 pieces and you have to sort by zip.
This also raises another issue that the Operations Team should consider, which is that at some point in our development, individual states will start raising enough annually that they will need to set up a legal nonprofit (preeclampsia.org/florida) for example and have a legal relationship with the PF. Essentially, this is an IRS test that depends on a formula based on annual income (per state) over a period of time and then averaged.
Thanks for raising the issue, Jodie, and for all the amazing work you do. Thank you so much for working so hard to get the word out.
