API
Your system creates one mailing per document, at the moment it produces the document. This suits recurring mail such as invoices and reminders.
Brazil mail API
Your PDF, printed the way you designed it
Logos, colors and layout come out as they are in the file. You choose color or black and white, and each mailing arrives in a well-finished envelope.
A clinic, a car service shop or an insurer, for example, can send a color reminder with its own logo when an appointment, a service or a renewal is due.
Invoices for customers who pay on paper
Many customers in Brazil still pay with the boleto that arrives with their invoice. Your billing system creates the PDF, and CartaFlow prints and posts it to each customer every month.
