PebblePost

Pioneer and category leader in Programmatic Direct Mail, bridging digital intent data with physical mail delivery

PebblePost pioneered the category of 'Programmatic Direct Mail,' combining the precision of digital advertising with the tangibility and engagement of physical mail. Founded in 2015, the company enables marketers to trigger personalized postcards and other mail pieces based on real-time online behavioral signals — such as website visits, cart abandonment, or product browsing — allowing brands to re-engage consumers in a differentiated, non-digital channel. The platform ingests first-party and behavioral data, matches it to physical addresses, and delivers highly relevant direct mail pieces within days of a triggering event. PebblePost occupies a unique niche in the AdTech ecosystem by offering an alternative to increasingly crowded and privacy-constrained digital retargeting channels. As cookie deprecation and signal loss have pressured traditional display and social retargeting, PebblePost's offline channel has gained renewed interest from performance marketers seeking incremental reach and higher engagement rates. The company serves retail, e-commerce, financial services, and subscription brands looking to drive conversions and reduce churn through a high-attention physical touchpoint. The company is headquartered in New York City and has raised meaningful venture funding to scale its technology platform and data infrastructure. PebblePost competes with traditional direct mail providers modernizing their offerings as well as emerging programmatic mail startups, but maintains a first-mover advantage and proprietary matching and measurement capabilities that differentiate it in the market.
