General Information / Handwritten Addresses

Handwritten envelopes get opened: the alternatives

Hand addressed envelopes have a significant impact on open rates and engagement. These envelopes stand out in a stack of mail and trigger curiosity and a sense of esteem in recipients. This psychological effect goes beyond mere content; it taps into our need for personalization and appreciation. Handwritten addresses signal that the sender values the recipient as an individual, making them more likely to open and engage with the content inside.

In contrast, printed envelopes lack this personal touch and are often associated with impersonal or junk mail. Research shows that hand addressed envelopes can increase open rates by up to 300% compared to printed ones. Attempts to replicate this effect with printed envelopes, such as using handwritten fonts or adding handwritten notes inside, fall short of the authenticity and uniqueness of genuinely handwritten addresses.

Overall, hand addressed envelopes leverage our psychological need for personalization, appreciation, and curiosity, making them a powerful tool for improving the success of direct mail campaigns and other correspondence. In essence, taking the time to write an address by hand may seem like a small detail, but it can have a profound impact on making a meaningful impression.

The impressive BRFKredit success story demonstrates that handwritten envelopes alone can already yield extraordinary results by leveraging behavioral science. Using handwritten envelopes not only saves the company money but also alleviates customer concerns and difficulties. In many contexts, it is worth considering the strategic use of handwritten envelopes or letters to achieve meaningful outcomes.

Type: Envelope1S

In the case of our Envelope1S format, only the recipient's address is written on the envelopes or labels. The sender's credentials are either printed on the envelopes or omitted.

"Hand-addressed envelopes gleaned almost three times as many responses compared to printed labels."

Type: Envelope2S

In the case of our Envelope2S format, the recipient's address as well as the sender credentials are written on the envelopes. The sender's credentials can be written on both the front or backside of the envelopes.

Type: Address Labels

We also create custom, genuine-looking handwritten addresses on address labels and have them delivered to you. This is an excellent option if you wish to infuse a personal touch into a campaign using boxes instead of envelopes. For instance, if you plan to send gifts to your corporate clients or provide product samples to social media influencers, it's an ideal choice. By doing so, you convey the message on the outside of the package that something unique is happening inside. This not only piques curiosity but is also seen as a gesture of appreciation.By default, we use the A6 format (148 x 105mm) for all such labels. We recommend using ballpoint pens instead of fountain pens, as this offers better protection against raindrops and similar environmental factors.
