<shameless plug> Thanks! Mailaletter.com is great, and we (Mailform) are a competitor. There's a few others you could check out: click2mail.com http://simplepostal.com http://simplepostal.com neopost.com clicksend.com papermail.in letterstream.com pingen.com elipso.eu postalmethods.com sendovernightmail.com (also owned by us btw) They're all pretty different along cost, features, delivery speed, etc. Cheapest probably depends how you define it (mailaletter is one of the cheapest if you're sending a single letter, click2mail is probably the cheapest if you're sending multiple, etc) here to help, team@mailform.io :)
