Our letters are rewarded with attention.

Handwritten mail signals appreciation, and appreciation gets rewarded with attention. That's exactly what our customers' results show.

PENSAKI has been running successful mailings for businesses for 12 years, and we deliberately do without any form of outbound sales. The success of our customers' mailings is the foundation of our existence.

No sales team of our own since 2014, no cold calling on our part. Customers stay and refer us onward because the results speak for themselves.

Why Handwritten Mailings Work

Five reasons that make the difference

Attention

Handwritten mail stands out instantly in the inbox, instead of getting lost in a flood of digital advertising.

Physical touchpoint

A real, tangible object creates a presence that purely digital channels can't reach.

Appreciation

Handwriting signals that someone took the time, not just that a system fired off a message.

Recall

Handwritten messages have been shown to stay in memory longer than purely digital touchpoints.

Response

As the customer results above show, handwritten mailings achieve significantly higher response rates than classic direct mail.
