As much as we thought email and PDF attachments would eliminate the need for envelopes and stamps and the postal service, it hasn’t exactly turned out that way. We still need to lick stamps and envelopes.
Mac users get Pages for free, and Pages lets you print envelopes and labels. If you need just a bit more but don’t want to pay the price of a more expensive label and envelope application, there’s EnvelopeCat. Cheap, fast, easy.
It handles nearly any envelope your printer can print. There’s a margin alignment tool to make sure the addresses go where they should. It even prints barcodes which helps the postal service speed delivery (allegedly).
Screenshots should give you an idea of how simple EnvelopeCat is to setup and use.
The print panel makes it easy to see exactly where both the return and recipient addresses are located. EnvelopeCat can also print multiple envelopes (subject to your printer, of course) one after the other.
There’s also a handy option to add a company logo graphic. Fonts can be customizes by style, color, and size. With standard sized envelopes all you need is to enter the address, or pull it from Contacts on your Mac, then press the Print button.
My experience with labels and envelopes is mixed, and success often seems to be the result of having a good printer vs. having good envelope printing applications. I prefer labels, but there are times when you need to print just a few envelopes and EnvelopeCat, though something of a one-trick pony utility, does it easier than mucking with two or three labels.
