Handwritten direct mail generates very strong results as showing appreciation is a key differentiator in todays digital world.

Surprise & delight with handwritten notes pay off.


Thanks to a growing flood of daily (advertising) information, people have developed very successful defense strategies, such as deleting e-mails in a split second, without even opening them. One can say that a real fight for attention has erupted. Creating attention works best through uniqueness and showing people intrinsic appreciation.

Uniqueness baffles, uniqueness is respected, and uniqueness in combination with appreciation delights people. Especially in the context of lead generation, customer acquisition and customer retention it is often the supposedly “little things” that led you stand out from the crowd. Doing something extraordinary can be crucial for the growth and success of your company. Either you successfully distinguish yourself in the flood of daily information, or you become part of the flood yourself. Creativity is a mandatory constraint in this context. 58 % of the companies that think of creativity as part of their corporate strategy have a yearly sales growth of at least 10 %. (Adobe Creativity Divide 2014). 


"Sometimes you need to take a step back in order to move two steps forward"


Sending authentic handwritten direct mail letters in the digital age is a sign of creativity, innovation – and especially of appreciation for your customers. That is why our customers regularly achieve lead conversion rates of 40 % in the context of their lead generation campaigns.

But handwritten letters are not a sufficient condition for sales success. More success factors need to be considered in order to achieve extraodinary results with handwritten cards, invitations or letters.

First to something basic: Either you write yourself, or you let someone write for you “by hand”. Pensaki sees itself simply as your private secretary. We support you if you can't write yourself or don't want to. 

The Key Success Factors of handwritten direct mail campaigns:


1.Relevance of content, without publicity or a plain sales pitch, but a really personal message. Keep it simple stupid/short.

2. Data quality and qualification of the recipients (relevant target group, correct form of address, postal address, etc.)

3. Authenticity of the handwriting / cursive & quality of the used stationery as an expression of appreciation

4. The sender is a person and not a company

5. Exclusivity of the "handwritten" channel, i.e. the recipient doesn't get the same message per email ...

6. Include a "Call to action" („Be our guest“, „Get in touch with me“, etc.)

7. Use real post stamps.

8. Quality of the stationery used (How to chose good stationery for handwritten notes)


A handwritten mailing can be realized quickly with Pensaki. But even the prettiest handwriting will only make an impact on the recipient if the message feels right. That is why you should invest enough time and work on the form and content of your text. Avoid strung-together phrases and don't annoy your reader with PR sayings. The handwritten mailing by Pensaki offers a unique chance: The external shape draws the attention of the reader. Rely on the KISS formula (Keep it short & Simple) – short sentences, relevant content and addressing the reader personally shows your appreciation of the other person. Present a clear “Call to action” (“Be my guest.”, “Get in touch with me.”, “Support me with...”), show that you are grateful or show your appreciation (“It was nice meeting you.”, “I'm looking forward to our project.”) or congratulate sincerely.


Furthermore, there a lot more factors that can raise your chances for success. We'll gladly advise you on this, so your Pensaki mailing can be a tremendous success as well.



Please take a look at a selection of our stories of success. There are a lot more achievements of our clients that we sadly can't publish, because a private secretary is characterized by reliability, trustworthiness and incomparable discretion.
