You can register for a free account at www.docmail.co.uk
You then have three options to use Docmail:
Web service - you can upload your documents and address, configure your mailings, view and approve your proof and we will do the rest for you.
Print Driver - download our free virtual print driver, then when you have your letter all ready to go, press print and choose the Docmail printer option.
API - If you would like to integrate your system with ours, for seamless mailings, then take a look at our API page.
You send your mailings to us, and we will print and post them, cheaper than you can even buy a stamp. The great thing is you don't even have to leave your desk.
