"...the handwriting conveys authenticity: if you look very closely, you see the irregularly distributed ink,the minimal imperfections of the fountain pen on the paper..."(brand eins Magazine)

"Beautiful, unique product + world-class service = unbelievable marketing"

"We came to Pensaki because we wanted to send Handwritten letters to several hundred clients. The clients were absolutely over the moon with the order - we couldn't be any happier with the response - and we'll certainly be using Pensaki again.Give them a chance. You absolutely won't regret it. Insanely good value for money and absurdly excellent service."

At Pensaki© (Japanese for fountain pen) all cards and letters are written by robots with a human handwriting style. For this purpose, fountain pens or ballpoint pens are clamped in a device, which then pens your message. Your messages and addresses are easily entered online. In addition, the data can be transferred via the Pensaki API for Robot Handwriting from all common CRM systems. Before mailing the letters our friendly employees check the quality manually.

In the digital age human socities have moved to content abundance and attention scarcity. As a result the daily fight for attention makes its critical to consider many details, supposedly little things decide whether communication is effective, i.e. successful or not. Handwritten letters are a very special way to make your message stand out from the crowd, i.e. your competition. Because behind every customer is always a human individual who wants to be perceived as such, i.e. unique, valued and understood. Who takes this into account in the context of marketing campaigns will be rewarded with outstanding success, provided that the success factors have been taken into account. Especially crisp, relevant and personal messages are rewarded with great success.

You can create and order all letters directly online at Pensaki. All standard letters will be mailed globally with Deutsche Post. Also mail-merge campaigns with 10,000+ recipients can be easily created online with Pensaki. Read here more about how Pensaki works.

Please always consider the very important success factors in order to achieve also outstanding results with Pensaki. By the way, the golden rule is: It can't be important if it doesn't fit on one page! So please keep the letters free from plain advertising and buzzwords. Keep it real! Successful letters are always personal, relevant and concise (read more here).

Handwritten direct mail campaigns are ideally suited in the context of two business scenarios. These are lead generation campaigns and loyalty / retention campaigns with existing customers.  This includes, for example, the following scenarios:

Scope: Lead Generation

A high-quality communication approach is particularly critical for the success of B2B lead generation campaigns, i.e when you want to engage with senior executives and decision-makers instead of time bandits. Handwritten invitations can play a critical role in this context with RSVP response rates north of 20 percent.

  • Invitations
  • Customer Win-Back
  • Reactivation Campaigns
  • Newsletter Opt In Campaigns
  • Sales Promotions
  • Referral Campaigns

Scope: Customer Loyalty

An Emotional Connection Matters More than Customer Satisfaction. That's why great brands aim for customers' hearts, not their wallets. Making an investment in optimizing the on and offline end-to-end customer experience has become critical for all leading companies. Handwritten messages can make a huge difference here.

  • Birthday cards
  • Thank you notes
  • Sorry Notes
  • Welcome Letters
  • Parcel Thank You Notes
  • Seasonal Greetings

Pensaki customers achieve outstanding results with our handwritten letters, provided that the success factors have been taken into account. Those who take them into account will be rewarded with outstanding success. Neutral letters are particularly successful in the lead generation context. This makes our unbranded standard formats ideal for such campaigns. Handwritten campaigns can provide noteworthy business results both in the B2B and B2C context. Driving customer retention campaigns with handwritten notes can make a huge difference when you want to convert satisfied customers to emotionally connected fans.
