Our website already saves countless hours of tedious work involved with sending mail, but you might be sending so much mail that you need an even faster way.
If so, the LetterStream API might be the solution you need. It allows you to automatically send thousands of pieces of mail instantly through a behind-the-scenes connection to LetterStream computer systems. Most APIs require programmers to implement them, and ours is no different in that regard, but some of our clients have implemented it in just a few days.
Our API is being used by many different types of companies, including software companies, collection agencies, billing companies, etc. and even individuals who need to send a lot of mail quickly. It has access to many of the mailing products available on our website including postcards, first-class letters, invoices, statements, newsletters, checks and certified mail.
You can advertise your partnership with LetterStream or keep it quiet and price the mailings to your customer however you see fit; because with the API your users and customers can send real mail without even knowing about LetterStream.
