How to Order Handwritten Envelopes

With all our PENSAKI standard letters, you can start the order process immediately.  Simply click on "ORDER NOW".

In the case of a PENSAKI tailor-made direct-mail campaign, you will receive an email from us with your personal access data. In any case, you must first register with PENSAKI so that you can save your drafts and create text templates.

Sending authentic handwritten sales letters has never been easier. After opening the online editor of the selected format, you can directly start entering your text. Each format has its own online editor. This means that the number of lines and characters per line (including spaces) differs accordingly. PENSAKI transfers your content exactly as you provide it, line per line. The personalization of the salutation is a standard feature. In addition, you can personalize all messages extensively with additional personalization segments.

Direct Mail Response Rates Compared: Standout or Standby.

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.

Email (only GDPR-compliant with double opt-in) ¹ : 1%
Print Direct Mail (GDPR-compliant without opt-out) ¹: 5%
Pensaki-letters (GDPR-compliant without opt-out) ²: 40%

Handwritten Envelopes Make Your Event Stand Out

Smart direct mail campaigns are far from outdated as many successful businesses rely on highly personalized direct mail to drive a constant flow of new leads, in the context of invitations to relevant events.  A handwritten invitation in a hand-addressed envelope conveys attention to detail, exclusivity, and quality and shows the recipient that they are special. Self-written invitations are always the best option, but if you lack the capacities or neat handwriting you can use Pensaki to do the job.

Physical direct mail campaigns are proven to have more influence than digital messages. Acquiring new customers or winning back customers with handwritten invitations has proven to be a very effective strategy, especially when you consider these success factors.  Handwritten invitations offer an outstanding opportunity to stand out from the competition.

Handwritten envelopes are practically always opened because they are simply impossible to ignore. At Pensaki you can order hand-addressed envelopes at scale to surprise and delight your customers, boosting open and response rates. While your competitors are drowning in a sea of cheap printed direct mail, your handwritten envelopes will convert.

There is a huge opportunity to stand out because there is a very important fact that is often forgotten: Communication is not the same as information.  The recipients of your handwritten invitations always also value the creative aspect and perceived costs that you invested("costly signaling").

With PENSAKI you can prove that traditional marketing is still a very valuable asset. The art of synergizing traditional marketing with digital marketing provides amazing opportunities for your company.
