Hi, Lob employee here! Mailform actually uses Lob.

Lob's focus is on building printing and mailing infrastructure accessible through our API. Mailform is creating an easy to use interface (via Lob) for customers to print their documents.

Hey Fabio- we are built on top of lob. They've been great to work with, and are very supportive of Developers like us.

Mailform is focused on consumers and businesses who want an easy way to print and mail (for sending tax documents, invoices, estimates, brochures etc). Email us at team@mailform.io with questions.
