(Cold) Response Rates with handwritten notes

Legally speaking, all business invitations are advertising. Therefore, sending an invitation (according to EU-GDPR) may also constitute an unreasonable nuisance. If the invitation is sent by email, consent with the double-opt-in is legally required beforehand. If the invitation is sent by direct mail, no prior consent is required. While recipient opt-ins aren't compulsory in the case of direct mail, gaining legitimate interest is. If your company can prove your campaign is of legitimate interest to those you are targeting, the need for consent disappears. This is unlike email marketing, where consent is always required. Cold contact by email, WhatsApp or SMS are not GDPR-compliant, whether for consumers or business. As a result, the DMA Response Rate Report 2018 demonstrate, high-quality offline mailings can make a very important value contribution.

Only writing a letter by yourself is cooler!

A legible handwriting, high-quality stationery, envelopes and stamps, not to mention the need to find a letterbox, are not required with Pensaki. You type. We take care of the rest for you.


"In fact, the handwriting conveys authenticity: if you look very closely, you can see the irregularly distributed ink, the minimal imprint of the fountain pen in the paper, the lines of letters that are not exactly parallel."

"The handwritten postcard promises attention - besides time, the most important resource in the media world."

"The Pensaki postcard is so unusual and so amazing, simply a great way to stand out from the daily media frenzy and to reach your audience effectively."

"A great company called Pensaki can create handwritten cards for you and send them directly. You don't have to worry about a thing, they'll do it all for you!"

" a robot takes over the writing: with a clamped fountain pen or ballpoint pen handwritten lines are created, which do not show that a machine was at work."

"The Pensaki handwriting on the envelope seems so realistic that I never suspected for a moment that the letter could come from the ≫Uncanny Valley≪ of robots and avatars."
