# Custom mail

As a direct mail automation platform, Lob's focus is to offer [set mail formats](/print-and-mail/designing-mail-creatives/mail-piece-design-specs.md) that can be programmatically sent at scale. These are postcards, self-mailers, snap packs, letters, and checks. However, for customers who need to send greater mail variations beyond these formats, we are open to exploring options with you. 

Please reach out to your Account Manager for more information on program eligibility and requirements.
