Awesome, and yes, barcodes DO work

I just printed out a ton of envelopes and it went perfectly with absolutely no errors. Anyone saying the barcodes don’t work are wrong: you need to go into Preferences and enter in your Mailer ID for Intelligent Mail barcodes, which is a USPS-issued number for business mailings. It took me five minutes to get one on the USPS website. If you don’t have one, you can use old style POSTNET barcodes, which also work fine, or just use no barcode at all. I even used an online decoder to validate that the Intelligent Mail barcode contained the right information, and it does. Anyway, the app does what I needed it to, although I wish it did address validation – but I won’t blame the app developer for what I know is a terrible (and expensive) USPS integration.
