Service review
Yellow Letter HQ Review
A real-estate-investor mailer with a tiered range: printed "yellow letter"-style postcards and letters at the low end and "real pen to paper" handwritten cards at the top. Bundles list management, skip tracing, and NCOA/CASS data hygiene. Public pricing ($0.55 postcards to ~$1.05 handwritten cards); the handwritten cards are real pen, though the human-vs-robot mechanism is unconfirmed.
