Using quickletter@postful.com
QuickLetter is the easiest and fastest way to send a letter. It is popular both for personal letters and as an easy way to integrate other applications with Postful.
Just send an e-mail to quickletter@postful.com with the mailing address in the subject line and we do the rest. You can include attachments (photos, PDFs, etc) as usual.
For international addresses, use semi-colons to provide explicit line breaks.

Advanced Options
You can adjust your return address on a per letter basis by including it in the subject line, separated by ||. This is particularly useful if you are using quickletter as the gateway to integrate with your application.
