Direct Mail Delivery Engine
Print Delivery Network
Lob’s Postal IQ routing intelligence chooses the most efficient USPS entry point for every mailpiece, helping your mail reach mailboxes quickly and cost-effectively by working in step with USPS operations.
We can have a mail piece printed and in the mail stream within two or three days – that’s a massive differentiator. That speed is critical for helping our customers meet compliance.
– Abby Warner, Chief Experience Officer
