Sincerely

Sincerely transforms B2B direct mail with a personalized, data-driven approach. Key features include: • Account-specific research for tailored content • Generates postcards, letters, handwritten notes, and gift notes • Full source attribution for all claims • Multi-format campaign sequencing to a single account • Human approval required before any printing • Integrated holdout testing for performance measurement This platform deeply researches each target company and recipient to craft highly relevant physical mail.

Sincerely enables sophisticated campaign orchestration by allowing users to sequence multiple mail formats—from postcards to personalized letters and gifts—to the same account over time. This layered approach helps maximize engagement and impact. A crucial feature is the account-level holdout group, which provides clear, measurable lift data, allowing revenue teams to understand the tangible impact of their direct mail efforts. Designed for B2B revenue teams, including SDRs, ABM programs, and demand generation, Sincerely helps create impactful outbound strategies. It integrates seamlessly into existing workflows, whether operated directly within its application or through other platforms, making it a flexible tool for enhancing customer acquisition and engagement.
