Overview

Our handwritten card with envelope is the most personal and premium option in the LettrLabs lineup. Each card is written in one of our 60+ handwriting styles, placed into an A8 invitation-style envelope, and finished with a real USPS stamp. This format is ideal when authenticity, intimacy, and high response rates are your goal.

Whether you’re thanking customers, following up on a high-value lead, or sending a win-back offer, handwritten cards stand out in the mailbox and make a lasting impression.
