Custom mail builder

Custom Mail Builder is currently in beta, and is available to Enterprise edition customers. Reach out to our sales team or to your Customer Success Manager to learn more.


As a direct mail automation platform, Lob's focus is to offer set mail formats that can be programmatically sent at scale. These are postcards, self-mailers, letters, and checks. However, for customers that have a need to send greater mail variations beyond these four formats, we are introducing a new option.
Custom Mail Builder is a brand new workflow that invites the customers to self-define a custom mail job with support from Lob's team of print experts, and order mail via Campaigns UI or API.

Beta program

Currently, we are accepting participants in our public beta for the following mail formats:
If either of these formats may be of interest to your team, please reach out to your Customer Success Manager for more information on program eligibility and requirements.
